By clicking Sign up for GitHub, you agree to our terms of service and How to reduce polling time to 60 sec? 1 minute is good for interfaces statistics, but for sensors, ie dbm on tranceivers, fan speeds etc 5 minutes is enough. Distributed Poller Support Matrix Shared FS: Is a shared filesystem required? I've just started poking around LibreNMS. Depending on many factors, you should see the Ops/sec drop by ~30-40%. Isn't the biggest problem having a polling cycle longer than a minute? Select RRDTool Setup and then update the two values for step and heartbeat intervals: We provide a basic script to convert the default rrd files we generate to utilise your configured step and heartbeat values. ", # Show Errored ports in summary boxes on the dashboard, # The description to look for in ifDescr. 1256230 21.5 KB What am I doing wrong? The script runs on a per device basis or all devices at once. Password minimum length for auth that allows user creation. Basically on your LibreNMS server you edit /etc/cron.d/librenmsand set the cron job to this:change to */1 * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16Then in the web interface, you navigate to Global Settings / Poller and change the values for the following:Change the rrd step valueChange the rrd heartbeat valueAccording to the documentation: Your polling MUST complete in the time you configure for the heartbeat step value. You can hack around at it on a single server but youll probably end up in a world of pain. OS specific definitions (includes/definitions/_specific_os_.yaml) can contain bad_if* arrays, but should only be modified via pull-request as manipulation of the definition files will block updating: Various bad_if* selection options available. Reddit, Inc. 2023. Do they RRD is going to be able to read that. if your rrdstep is 60 seconds. To get a complete list of all the current values, you can use the command lnms config:get --dump. Having done 1-minute polling in Cacti I get the RRD changes. The rrd files must be accessible from the server you run this script from. Valid options for email_backend are mail, sendmail or smtp. Will grab the logs today and that may shed some light. Database config takes precedence over config.php. Krystal is proud to help support LibreNMS with the Cloud services through our Katapult platform. The config is stored in two places: Database: This applies to all pollers and can be set with either lnms config:set or in the Web UI. I compare with my other EX4550 stack with 200 ports that has a polling time of 161.50 seconds. The text was updated successfully, but these errors were encountered: Hmm. Anyways, If you dont mind, why you need less than 5min polling? (Which we wouldnt want to do). The output may not be desirable, so you can use the jq package to pretty print it. * * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16. ==================================== This wouldnt alter much code but more masquerade the filenames in certain conditions. NOTE: This list of SNMP communities is used for auto discovery, and as a default set for any manually added device. With 5 min resolution, it is often masked. Hi Folks,I made this video to show how to change the LibreNMS poller to 1 minute instead of every 5 minutes which in my opinion is much better for a lab envi. This is the default message on the login page displayed to users. You can override a large number of visual elements by creating your own css stylesheet and referencing it here, place any custom css files into html/css/custom so they will be ignored by auto updates. This setting has an order of precedence Device > OS > Global. The ports.ifSpeed test is to cause the rule to ignore ports with link speeds of <50Mbps (10Mbps) as most of our PC's switch from gigabit to 10Mbps when they go into wake on lan standby, this can sometimes trigger bandwidth alerts because the previous 5 minutes worth of data throughput may be more than 8Mbps and LibreNMS now thinks the port is on. ```bash lnms config:set ignore_mount_removable true lnms config:set ignore_mount_network true lnms config:set ignore_mount_optical true. When installing LibreNMS for the first time with a new database you can place yaml key value files in database/seeders/config to pre-populate the config database. I don't see an obvious config that allows me to move this interval down. Or more accurately, for 1 min resolution (weather that's polling, graphing, whatever). LibreNMS configuration is a set of key values. But, which value to update in the cron.d concerning poller-wrapper.py ? You may enter any free-form text including one or more of the following template replacements: For example, {{ $sysName_fallback }} ({{ $ip }}) will display something like server (192.168.1.1). i'm wondering if there is a way to poll groups of devices in diffrent intervals? Some devices register bogus sensors as they are returned via SNMP but either don't exist or just don't return data. Below you will find the standard options, all of which you can configure. Or can you pull the groups on the same host? lnms config:get will fetch the current config settings (composite of database, config.php, and defaults). Putting the RRDs on a RAM disk. I doubt you will be able to do this. I don't see any issues for my equipment. Not all settings have been defined in LibreNMS, but they can still be set with the --ignore-checks option. You can increase this if you want to try and fit more of the hostname in graph titles. I've got snmpd set up on three VMs, one for docker, for pihole and for pivpn. Disable the footer of the WebUI by setting enable_footer to 0. Im guessing the hacky way is not as simple as adding an additional cronjob for the new polling group? Scan this QR code to download the app now. :). I'm wondering if there's a way to modify the polling interval on the cron. Administrators are able to clear the last discovered time of a device which will force a full discovery run within the configured 5 minute cron window. NOTE: This feature requires your client version of rrdtool to be 1.5.5 or newer, in addition to your rrdcached version. +1 for < 5 min polling. Vendors may give some limit values (or thresholds) for the discovered sensors. Performance data for the poller can be seen on the "Polling Information" page at /pollerlog/ on your Observium installation. Perhaps use kibana instead.. perhaps a workaround? Entries defined in rewrite_if_regexp only replace the match. Please do ensure that you backup your RRD files before running this just in case. At the higher speeds, the counters increment at a higher rate. For more information, please see our By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Configs set here will be disabled in the Web UI to prevent unexpected behaviour. If you would like to do this on a per device basis then you can do so under Device -> Edit -> Misc -> Disable ICMP Test? This allows you to ignore those based on the descr field in the database. This is something I'd like to consider, but it will require some significant changes to how the poller data is stored, so it will take some time & thought. By default, when no such value is given, both high and low limit values are guessed, based on the value measured during the initial discovery. 40 Posted by u/d3adbor3d2 1 year ago LibreNMS questions I've just started poking around LibreNMS. You can override this setting per-device. add the following to your nginx.conf file: Add this to /etc/nginx/streams-available/rrd. LibreNMS. I know RRD will not get much benefit from this, but my Grafana and other tools that digest the InfluxDB data can do lots with more data. To run it for localhost just run: This will only affect RRD files created from the moment you change your settings. Chas 26 March 2018 15:26 #3 Thanks Kevin With over 33,000 happy customers, Krystal provides a range of services from web hosting through dedicated servers to public cloud and more. This document will explain how to use poller.php to debug issues or manually running to process data. You can enable dynamic graphs within the WebUI under Global Settings -> Webui Settings -> Graph Settings. I typically do much more sophisticated aggregation and visualization using Grafana, and it seems like a win to have LibreNMS forwarding that back at a higher speed rate even though RRD isn't suitable for the lower interval. # false- only check when adding host by ip. I think it is best to use something else for outage alerts like Icinga. Enable this to switch on support for libvirt along with libvirt_protocols to indicate how you connect to libvirt. Reasoning is if you have a 5m polling interval (default), your alert rule is set to delay 1m, so your devices might alert false-negative device downs because they aren't through the polling cycle and there wont be another subsequent update for as many minutes as your polling interval to clear tell you its clear. If device sysLocation information contains [lat, lng] (note the comma and square brackets), that is used to determin the GeoCoordinates. It seems the default polling interval is 5 minutes. Here is my librenms crontab - Using this cron file requires an additional user on your system, please see install docs. Is there a way to get them to poll more often? Disk I/O can be found under the menu Devices>All Devices>localhost hostname>Health>Disk I/O. Right now i just have it on my laptop running on virtualbox. So far i'm liking the interface design and im thinking it's a good candidate to replace what we have (we've used tools like mrtg, prtg,cisco pi, solarwinds, airwave). NOTE: change IPADDRESS to the ip the rrdcached server is listening on. Cookie Notice We now have support for polling data at intervals to fit your needs. Of course I can change cron now and it will redraw evey min. So if the module is set at a more specific level, it will override the less specific settings. The same for discards, overflows and other congestion values. Generate a non-password-protected ssh key for use by LibreNMS, as the user which runs polling & discovery (usually, Configure public key authentication from your LibreNMS server/poller by adding the librenms public key to, (xen+ssh only) Enable libvirtd to gather data from xend by setting. Using a socket allows the collectd graphs to be flushed to disk before being drawn. Ok Great, Thanks for the suggestion Laf Ill give it a go and see how manageable it is. On. This is a simple template to control the display of device names by default. This is all about the Polling and Discovery Processes with LibreNMS. It does not replace the php scripts, just the cron entries running them. If you just want to set GPS coordinates on a location, you should visit Devices > Geo Locations > All Locations and edit the coordinates there. Hi Folks,I made this video to show how to change the LibreNMS poller to 1 minute instead of every 5 minutes which in my opinion is much better for a lab environment. 1.4.1 Discover and . You can use this array to rewrite the description of ASes that you have discovered. From the link you posted https://docs.librenms.org/Support/1-Minute-Polling/ it seems your value in cron should correlate to the value of the rrdstep you set up in the web ui. You can disable the fping / icmp check that is done for a device to be determined to be up on a global or per device basis. You can have the polling interval you want (if your poller(s) can handle) but you cant have different intervals. If host is added by hostname this check is not performed. On the devices page I click on pihole and click Alerts aaaaand it's empty. I typically do much more sophisticated aggregation and visualization using Grafana, and it seems like a win to have LibreNMS forwarding that back at a higher speed rate even though RRD isn't suitable for the lower interval. Log files created by LibreNMS will be stored within this directory. Should be set to dashboard_id of an existing dashboard that is shared or shared(read). To be honest, 1 minute polling would be useful for a few ports/critical stuff in my typical use case for LibreNMS (we run one of the biggest Lan in North America). Please see 1 Minute polling for information on configuring your install to record data more frequently. The default value is 12 However, this can possibly break graph generation if this is very long. Probably need to change the standard php scripts? After at least one poll cycle (5 mins), check the LibreNMS disk I/O performance delta. To enable this set the following config: This setting has to be the exact version of rrdtool you are running. Reddit, Inc. 2023. All rights reserved. You also need to: To test your setup, run virsh -c qemu+ssh://vmhost/system list or virsh -c xen+ssh://vmhost list as your librenms polling user. 1 minute is good for interfaces statistics, but for sensors, ie dbm on tranceivers, fan speeds etc 5 minutes is enough. We really won't get much value out of increasing the polling rate until we can overhaul the RRD creation code, which is tricky because it's scattered all over the app at the moment. For a list of modules please see Poller modules SNMP Max Repeaters Official sub-reddit for the LibreNMS project, a community-based, GPL-licensed autodiscovering network monitoring system. to your account. 1: Create /etc/systemd/system/rrdcached.service with this content: This example is based on a fresh LibreNMS install, on a minimal CentOS 6 installation. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. For more information, please see our In this example, we'll use the Repoforge repository. Just curious as to why you want multiple poll periods? So I guess I would need to have Weathermap somehow pull from Influx and change the cron line for weathermap poller down from */5 to */1. Be sure that your web server has permissions to write to this socket. You can disable image lazy loading by setting this to false. next, we'll symlink the config to streams-enabled: ln -s /etc/nginx/streams-{available,enabled}/rrd, Disable the [rpmforge] and [rpmforge-extras] repos again. If this is set to true then an overview will be shown on the login page of devices and the status. Do they RRD is going to be able to read that. Whereas we have some routers with lots of cards/ports which complete polling in 3 minutes so really we need to leave these to 5 minutes. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. To do so you can proxy rrdcached using nginx to allow only specific IPs to connect. If the setting is true hostnames are resolved and the check is also performed. Is it possible to have polling intervall of 2 minutes? I had a look at distributed poller (https://docs.librenms.org/#Extensions/Distributed-Poller/#distributed-poller) , but that looks like its meant for multiple servers? It seems the default polling interval is 5 minutes. Privacy Policy. It seems that LibreNMS is a nice SNMP tool that takes care of a lot of the heavy lifting of determining "what" needs to polled, and the RRD views and other tools are a very nice set of standard instrumentation. If I go to the polling history of one of this devices, shows that polling time takes 2.5seconds and las polling has been 8 minutes ago. I changed my poller intervals last night and my graphs are not updating correctly. Otherwise, the system will automatically create each user an empty dashboard called Default on their first login. Using the same setup above, using nginx version 1.9.0 or later, you can follow this setup to proxy the default rrdcached port to the local unix socket. You signed in with another tab or window. bad_ifalias_regexp is matched against the ifAlias value as a regular expression. For example, a server can go offline for 30 seconds and then come back. Graphs will be movable/scalable without reloading the page: You can enable stacked graphs instead of the default inverted graphs. Influx with Weathermap, that's not possible but is obviously a weathermap question rather than one for us. The varying options after that are to support the different transports. # true - check for duplicate ips even when adding host by name. i.e. Please be aware of the following: If you just want faster up/down alerts, Fast Ping is a much easier path to that goal. The default v3 snmp details to use, you can expand this array with [1], [2], [3], etc. Youd have to not user the poller-wrapper and use poller.php but it will result in horrible performance. Matches are compared case-insensitive. Which means that you get something a little more interesting than 5-minute resolution, but not by much. 33*/16 * * * * librenms /opt/librenms/cronic /opt/librenms/discovery-wrapper.py 1 Example: In this example, interval will be overwritten by the timeout value of 3000 which is 3 seconds. Im trying to do something similar to this thread Run difference poller groups: Thats the only real way. LibreNms poller Performance metric Interface graph not accurate Kevin_Krumm 26 March 2018 15:06 #2 Chas: How can I achieve this on just the one server, to poll at 1 minute and 5 minute intervals for different devices. I'm honestly perfectly fine with this. Is it possible to have polling intervall of 2 minutes? ~KEM This feature is primarily for docker images and other automation. Well occasionally send you account related emails. Have read quick over the docs and it seems that you need to setup more devices to pull to get this to work?https://docs.librenms.org/Extensions/Distributed-Poller/. The above are examples, these will rewrite device snmp locations so you don't need to configure full location within snmp. With a 4.9/5 score on Trustpilot, you're in safe hands when it comes to choosing a trusted partner to help . http://docs.librenms.org/Extensions/Poller-Service/, http://docs.librenms.org/Extensions/Distributed-Poller/. I have multiple 10G,40G and 80G ports/channels. Set these variables either in .env (/opt/librenms/.env by default) or in the environment. Can have multiple '["cust","cid"]', # Add custom transit descriptions (array), # Add custom peering descriptions (array), # Add custom interface descriptions (array). 2: Edit /etc/default/rrdcached to include: 2; Edit /etc/default/rrdcached to include: For remote RRDCached server make sure you have network option in /var/default/rrdcached. Next it will attempt to look up the sysLocation with a map engine provided you have configured one under $config['geoloc']['engine']. You could do a full install of LibreNMS in another dir to run as an additional poller. Enable / disable certain menus from being shown in the WebUI. You can disable the mouseover popover for mini graphs by setting this to false. If 2 pollers could poll the same device was a question on my part. The LibreNMS dispatcher service ( librenms-service.py) is a new method of running the poller service at set times. I recently setup 1 minute polling which works well, but I now need to run 5 minute polling to a group of devices. Have a question about this project? Just check https://docs.librenms.org/#Support/1-Minute-Polling/ and instead 1min polling, setup 2min, 3min or whatever you want. Default SNMP options including retry and timeout settings and also default version and port. The default array contains more items, please see misc/config_definitions.json for the full list. Right now i just have it on my laptop running on virtualbox. I'm honestly perfectly fine with this. I'm using the higher polling rate to have quicker alrets for outages, but I use the collectd integration for the more granular graph data. Any extensions that have dedicated documentation page will be linked to rather than having the config provided. According to the man page, under "SECURITY CONSIDERATIONS", rrdcached has no authentication or security except for running under a unix socket. https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS. Just adding comment here to serve as a vote for wanting to see this. If it's at 5 minutes, that's fine. When it is preferred to have no high and/or low limit values at all if these are not provided by the vendor, the guess method can be disabled: It is possible to filter some sensors from the configuration: Mounted storage / mount points to ignore in discovery and polling. I don't honestly care if the graphing stays showing 5 mins (for longer term data than 2 hours that's all you want anyway). we create an option, for example high_precision_modules, and let it contain the poller-modules one like to have with say 1m resolution. This helps prevents accidental duplicate hosts. Is the only way to accomplish this currently to use distributed pollers on different servers? I wish there was a way to tag ports for a custom polling cycle and even have a custom timer for up/down devices (if it relies on icmp). stupid question here: This can be a bad_if value as well which would stop that port from being ignored. Or Variable polling? For alerting and the callback functionality, we support the use of a http proxy setting. (You can use ./conf.d for your configuration as well), mkdir /etc/nginx/streams-{available,enabled}. When installing LibreNMS for the first time with a new database you can place yaml key value files in database/seeders/config to pre-populate the config database. If you decrease the values then please be aware of the increase in space use for MySQL and InfluxDB. All of my servers are polled once per minute using it and the hp network switches which take nearly 2 minutes to respond to a poll are just polled constantly. You can either ignore globally or on a per os basis. "Unauthorised access or use shall render the user liable to criminal and/or civil prosecution. Entries defined in rewrite_if are being replaced completely. I know I probably cannot count of the speed of the poller with 3k + Ports with our not-so great servers. As polling by modules is supported already it would only need a small addition to the pollerwrapper to pass on module args my 2 cents.. probably have missed something.. 1 minute polling time was my goal in writing #1405. You can change the memory limits for php within config.php. To enable this set the following config: $config['rrdtool_version'] = '1.5.5'; This setting has to be the exact version of rrdtool you are running. Kevin_Krumm 10 July 2019 19:37 #2 rokkhan: been polled within 10 minutes and none of them lasts more than 50seconds polling. if bad_if and good_if both contained FastEthernet then ports with this value in the ifDescr will be valid. I have no doubt it is a big effort, but if someone doesn't ask, it wont happen. and our good_if is matched against ifDescr value. See the separate Persistent RAM disk RRD storage page to find out how to set up a RAM disk with sync to the disks so you don't lose your data when your machine crashes/reboots. NOTE: Setting a higher timeout value than the interval value can lead to slowing down poller. I suggest you to also use the fast ping check, Powered by Discourse, best viewed with JavaScript enabled. LibreNMS noticed that the interface docker0 in the docker VM was down but I told LNMS to ignore it, but LNMS is showing warnings for my other two VMs but I can't figure out what they are. It happened every time when the device were mis-configured and I moved from a single poller to a distributed poller. You can create your own front page by adding a blade file in resources/views/overview/custom/ and setting front_page to it's name. Some pages don't refresh at all by design. 3 comments Contributor nertwork commented on Feb 26, 2019 Hello! Any documentation on how to get Influx working with Libre and/or weathermap by chance? To make the changes, please navigate to /settings/poller/rrdtool/ within your WebUI. lnms config:set will set the config setting in the database. Not sure how/if graphing will work. Currently we have a number of styles which can be set which will alter the navigation bar look. Then it would be lnms config:get --dump | jq. Setup the types of IPMI protocols to test a host for and in what order. Is there a way to get them to poll more often? Allows the specification of a global default dashboard page for any user who has not set one in their user preferences. Don't forget to install ipmitool on the monitoring host. External Requirements A recent version of Python The LibreNMS service requires Python 3 and some features require behaviour only found in Python3.4+. You can do this globally in config.php like: Disable OSPF polling $config [ 'poller_modules' ] [ 'ospf'] = false; You can disable modules globally then re-enable the module per device or the opposite way. Without that option input is checked for correctness, that does not mean it is not possible to set bad values. The preferred method for ignoring interfaces is to use an OS specific array. Replace $LibreNMS_IP with the ip of the server that will be using rrdcached. Ok, Im agree with you but, in the cron entry " */5 * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16", which is the value i need to change ? What is the difference between "* * * * * " and */1 * * * *? You can configure these options within the WebUI now, please avoid setting these options within config.php, Settings -> External Settings -> RRDTool Setup. Powered by Discourse, best viewed with JavaScript enabled, Replace RRDtool with another time-series database, 1 minute and 5 minute polling on the same server, https://docs.librenms.org/#Extensions/Distributed-Poller/#distributed-poller. The default arrays can be found in misc/config_definitions.json. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Sign in What type of mail transport to use for delivering emails. You are able to adjust the number and time frames of the quick select time options for graphs and the mini graphs shown per row. Kinda like:Group one of 300 devices gets pulled every 10 * * *Group two of 300 devices gets pulled every 20 * * *Group three of 300 devices gets pulled every 30 * * *. Filter all 'current' sensors for Operating System 'vrp'. This change will affect all data storage mechanisms such as MySQL, RRD and InfluxDB. It isnt an issue for the equipment, but a granularity problem. No matter what is used for alerting, the data has to be collected first, Data for alerting is collected at any desired rate. Check to see if the graphs are being drawn in LibreNMS. nice, and the RRD convert script that you need to run , will that work too? Disable polling (and discovery) modules that you do not need. Specify the location of the collectd unix socket. Experimenting with LibreNMS here, with a fork of data going to InfluxDB. bad_if_regexp is matched against the ifDescr value as a regular expression. Ideally one would like to have both, 1 min for interface stats and sensors at maybe even 10 minutes polling. Setting rancid_ignorecomments will disable showing lines that start with #, Specify the location of the collectd rrd files. As long as I can get < 5min weathermap data for all my ports. Just curious. However, I have a bunch of services setup for monitoring that use the check_http functionality ( i think old nagios plugins ) These only check every 5 minutes as well. NOTE: This feature requires your client version of rrdtool to be 1.5.5 or newer, in addition to your rrdcached version. Right now it's running every five minutes but I was hoping to get it down to every two minutes. Am I just missing that 1m intervals are possible? This will provide the help information. You can overwrite each device sysLocation information in the webGUI under "Device settings". Campus Network Design Workshop. The LibreNMS uses dot notation for config items: The documentation has not been updated to reflect using lnms config:set to set config items, but it will work for all settings. Agreed that having custom polling intervals on certain devices or ports would be ideal, which might mitigate the issue somewhat. This will bind nginx to TCP 42217 (the default rrdcached port), allow the specified IPs to connect, and deny all others. If a host is added as an ip address it is checked to ensure the ip is not already present. Please report missing settings. Already on GitHub? I was wondering if any long time admins of LibreNMS can chime in about it: how it compares to your previous nms, are there surprise costs, support, what is it NOT good for, etc. Or is it set to 1 or 5 minutes? If the ip is present the host is not added.

If you set up bash completion, you can use tab completion to find config settings. *************************************Music: sunny from Bensound.com************************************* For example, if you create resources/views/overview/custom/foobar.blade.php, set front_page to foobar. A 1 minute polling rate would provide the visibility needed. All rights reserved. We now have support for polling data at intervals to fit your needs. Plus, even if you send the data to influxdb, the rrd files are still being updated and they are set to a 5 minute interval. LibreNMS pulls a lot of data so that restricts the poll frequency. Higher resolution then 5 mins average on interface throughput. Averaging over the larger value makes the data less precise. However, I have a bunch of services setup for monitoring that use the check_http functionality ( i think old nagios plugins ) These only check every 5 minutes as well. Since version 1.5, rrdtool / rrdcached now supports creating rrd files over rrdcached. Shared FS: Is a shared filesystem required? Or is it set to 1 or 5 minutes? Heartbeat is how long to wait for data before registering a null value, i.e 120 seconds. This might take a few minutes. https://docs.librenms.org/Extensions/Distributed-Poller/. 1.2.1 Connecting to your LibreNMS server; 1.3 Looking at the LibreNMS configuration. @f0o @clinta You can add more than one value during the interval, but RRD will only record the average and maximum of them. You can override the default logo with yours, place any custom images files into html/images/custom so they will be ignored by auto updates. Enabling them is possible via webui Global Settings -> Webui Settings -> Graph settings -> Use stacked graphs. It's working very well for me, I'd encourage you to test it out. These can be any one of the following: We can also make use of one of these environment variables which can be set in /etc/environment: LibreNMS will attempt to detect the URL you are using but you can override that here. Command options LibreNMS uses traceroute to record debug information when a device is down due to icmp AND you have lnms config:set debug.run_trace true set. It would be nice if the polling log listed the time it took to complete the poll. We don't advise disabling the fping / icmp check unless you know the impact, at worst if you have a large number of devices down then it's possible that the poller would no longer complete in 5 minutes due to waiting for snmp to timeout. Otherwise I like the idea of scalable distributed pollers . LibreNMS can interpret sysLocation information and map the device loction based on GeoCoordinates or GeoCoding information. Assign a new discovered Port automatically to Port Group with this Port Group ID (0 means no Port Group assignment), Rancid configuration, rancid_configs is an array containing all of the locations of your rancid files. The information has to be accurate or no result is returned, when it does it will ignore any information inside parentheses, allowing you to add details that would otherwise interfeeer with the lookup. By default we allow hosts to be added with duplicate sysName's, you can disable this with the following config: Enable or disable discovery or poller modules. Ideally one would like to have both, 1 min for interface stats and sensors at maybe even 10 minutes polling. With 10Gbit interface now a standard in data centers and 40Gbit/100Gbit interfaces becoming common, the current 5 min polling rate is not fast enough. So far i'm liking the interface design and im thinking it's a good candidate to replace what we have (we've used tools like mrtg, prtg,cisco pi, solarwinds, airwave). Enable or disable the sysDescr output for a device. Only data for graphing is capped at 5 minutes due to the current implemented RRD-format.
