why are metric name getting that complex?

HelloI’m trying to understand why are the perfdata collected by some plugins are getting so much information in the metric names, and  is there a way to filter/rename themRight now I’m using centreon 20.10, with plan to upgrade to 21.10, so maybe all this below won’t make any sense, or is explained by some evolution I have yet to discover. I had to monitor some ubiquiti unifi AP and Aruba Instant SSL recently, but instead of getting simple cpu/load or traffic metric I get some output that are difficult to work with example for here is the output for Aruba : usr/lib/centreon/plugins//centreon_aruba_instant_snmp.pl --plugin=network::aruba::instant::snmp::plugin --mode=ap-usage --hostname=10.10.10.10 --snmp-version='2c' --snmp-community='test' --filter-name='' --warning-status='' --critical-status='%{status} !~ /up/i' --warning-cpu='' --critical-cpu='' --warning-clients='20' --critical-clients='50' --warning-mem-usage='' --critical-mem-u

Perfdata and graph visualization

Hello !When you monitor a host the values in perfdata have the max values.Is it possible to visualize this max value into Centreon grahs, without exploding the max value ?I don’t want to use the explode perfdata, because I already have multiple value into the graph.For examples :[centreon-engine@xxxxxx plugins]$ ./centreon_plugins.pl --plugin=apps::monitoring::netdata::restapi::plugin --mode=disks --hostname=xxxxxxx --proto=https --fs-name='^(?!(/dev|/run|/boot|/srv/varoptbesclient))' --filter-perfdata='usage.bytes' OK: All partitions are ok | '/#storage.space.usage.bytes'=4778252585B;;;0;9923968936.12933 '/appli#storage.space.usage.bytes'=73429015B;;;0;2936442404.10378 '/appli/log#storage.space.usage.bytes'=6856700B;;;0;1922490497.70885 '/appli/var#storage.space.usage.bytes'=1240043494B;;;0;30312924081.8156 '/home#storage.space.usage.bytes'=222396413B;;;0;952840212.604518 '/tmp#storage.space.usage.bytes'=17592293B;;;0;3861790960.54333 '/var#storage.space.usage.bytes'=

Do ping is required to monitor host status.

Hello We are deploying a centreon community edition. However in our environment ping is disabled as a security guidelines. We have added few hosts for the monitoring and as ping is disabled the host status is showing down. Please let me know is there any other way out to address this issue.

[Known issue] Broker might take a very long time to start completely

This issue should be fixed very soon, but I prefer signaling it here: on Centreon platforms having tens of thousands services and using the BAM module, the central broker daemon needs time to completely load its cache due to SQL queries that take too long to return the cache entries.The symptoms are that after a restart of the `cbd` service, the “last update” time will remain frozen for each poller for a while, and the “top counter” icon in the black banner will warn you that some pollers are not up-to-date.Once the cache is loaded, the broker daemon will catch-up handling the monitoring data and will work properly.The team is actively working on this issue and a fix will soon be released (before the end of January, hopefully). This issue is also referenced here (French version here).Fix release status:centreon-broker-20.10.11: Released centreon-broker-21.04.6: Released centreon-broker-21.10.1: Released

Volatile and Flapping

Ciao!My question start from a passive service in relation with the traps linkDown and linkUpFrom test, and reading the centreon-engine code, it seems that Volatile is checked before Flapping.Because Passive Service are usually, and by default with plugin pack, with “Is Volatile = Yes”, the notification filter of flapping state is never executed.https://github.com/centreon/centreon-engine/blob/develop/src/notifier.cc#L278So, in my case, when an interface start to flapping, the service also become in flapping state, but the engine still sent the notification.What do you think of change the engine, notification section, so it will check flapping before volatile?

Exclamation mark (!) not supported as argument in Services by host group

We recently started over with Centreon 21.10.1 to replace our Centreon 2.5.2 as a front-end for Nagios. While setting up the new system, we ran into a bug. In v2.5.2, we were able to escape the special character “!” in check command args for Services by host group. In v21.10.1, using “!” or “\!” as an arg value is simply stripped when saving configuratin. We have a very widespread SNMP community name that contains a “!” character.The check command is quite simple “$USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o .1.3.6.1.4.1.318.1.1.1.2.2.1.0 -w $ARG2$ -c $ARG3$ -l 'Adv. Battery Capacity' -u '%'” with “$ARG1$ being the SNMP community string.

About centreon-collect, the new Github repository for Data Collection

Data collection components’ source code is now centralized in https://github.com/centreon/centreon-collect/.How it was before?For major releases until 21.04, source code has been (and is still) hosted in 4 distinct repos:https://github.com/centreon/centreon-engine: the monitoring engine https://github.com/centreon/centreon-broker: the broker component, which handles the communication https://github.com/centreon/centreon-connectors: optimizations for Centreon’s Perl plugins and checks performed via SSH. https://github.com/centreon/centreon-clib: common libraries for the above componentsWhat was wrong with that?Building the binaries manually from the source was quite tedious since the four repositories had to be cloned, and then compiled in the right order: clib needed to be compiled and installed first.In our continuous delivery chain, this resulted in the necessity to rebuild new containers with every new version of centreon-clib.How it is now?Starting with major release 21.10, all the

Centreon Plugins - Discover Collection modesTutorial

The Centreon Plugins team recently introduced a new fashion of scraping monitoring indicators. It’s called Collection.  These modes could be seen as 'dumb' boiler-plates, allowing you to monitor 'things' over various protocols or APIs while abstracting some of their complexity. Collection modes rely on a JSON configuration file describing the data you want to get and the processing or mapping you may wish to apply. This kind of mode is handy if you are in one of the following situations:You can't find an existing plugin to monitor what you want or fulfill your particular need. You need to gather data from a in-house, black box, or third-party application and transform it to be easier to analyze. Writing (or asking for) a dedicated plugin appears overkill because you simply want to monitor values and apply thresholds over them. Currently, Collection modes are available for: SNMP (check the tutorial) SQL (check the tutorial)In other words, you can use these on any device supporting SNMP
