Base de données pleine

Bonjour, J’ai actuellement 4 pollers et un serveur Central et je supervise environ 2000 hôtes et 4500 services.Petite question concernant la base de données Centreon qui me donne du fil à retordre. Le répertoire /var/lib/mysql/centreon_storage occupe beaucoup de place et dedans, j’ai plein de fichiers *.ibd (pour la table data_bin) allant de 100 Mo à 1 Go. Est-ce que je peux supprimer à la main les fichiers .ibd les plus anciens avec un rm pour faire de la place ou est-ce qu’il y a une autre manière de procéder ? Version : 20.10.12 Merci d’avance !

Reports on Uptime

Hello Community, I need to do a report on Uptime from all of my servers (windows or Linux).I have the service that give me the uptime of all of my servers configured.they are all in state OK because I didn’t create warning or critical limits. I only have a “time”.But I don’t find the adequate report to have all these data reported.I just need a report with host and uptime. I think the issue is all events are in OK state. Could you help me? Laurent

SNMP Traps - Pending status persists

Hello,In order to test passive checks on my Centreon i have configured SNMP Trap for changing on the running configuration.Tthe switch i try to monitor is Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE10a.I use the passive check OID : .1.3.6.1.4.1.9.9.43.2.0.2 that was already built in Centreon.But when i’m trying to test this OID my service, it still be on “pending”.My configuration receives the check because i can see on my logs this output :I have followed https://docs.centreon.com/fr/docs/20.04/monitoring/passive-monitoring/enable-snmp-traps and https://docs.centreon.com/fr/docs/monitoring/passive-monitoring/debug-snmp-traps-management to debug my configuration.Do you have any suggestions to resolve this problem ?Thanks a lot.

How to facilitate the export configuration pollers

Hello,I’m new on Centreon’s administration, and really surprised by the click number needed to export configuration on pollers. If I’m not wrong (on 21.10) :Click pollers Click configure pollers Click name of the poller(s) to update Click Export configuration Click Move Export Files Click Restart Monitoring Engine Click ExportIs it the correct procedure, or is it possible to simplify it, with a clapi script or anything else ? Thanks to the communityPierre

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

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.
