Centreon Infra Monitoring

Hello,I got some issues with my WMI checks.When I start the service and the controls are reloading I got the notice that it’s gathering information for the next check and once it’s done it change state for OK.After a few minutes once the WMI check is newly scheduled it change state for UNKNOWN with the detail “No hostname specified” and it’s the same for any WMI services checked by Centreon.Meanwhile I tried to execute control in command line user the centreon user and it works perfectly fine. Does anyone already meet this issues here? Best regards,SEDKAOUI Julien

Can you help ? Much appreciated.RegardsGaetan 

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

Hi,Our company recently bought another one, I want to monitor them as I do for us.The other copany is linked via an ipsec tunnel, their bandwith is currenly low (2-5Mb/s)Instead of having two servers, I did install a poller and link it to our current server.Is the bandwith enough for that ?--The poller is currently installed (v21.10.2 as well), i’m trying to register it.https://docs.centreon.com/current/fr/installation/installation-of-a-poller/using-centreon-iso.htmlInstead of using the admin account, I created an api account, that has the right to use the api (for safety reasons)/usr/share/centreon/bin/registerServerTopology.sh -u USER -t poller -h SERVERIP -n POLLERNAME When I try to log in via http it tells me ‘invalid’ credentials, i’m copying the password directly so it can’t be wrong.So here is my question, the api account has to exist on the poller or on the server ?- ERROR - http://SERVERIP:80: {"code":401,"message":"Invalid credentials"} Also at first i wanted to use https for

Hello watchers, I have a little issue with backupage monitoring on SQL server.I explain:We have multiple MSSQL servers in our organization.We configured MSSQL plugin to monitor them.We do a full backup every friday and an incremental every day (Tlogs every hour).In Centreon, it seems it just take the full backup value to have the backupage value. Is it normal? How can I do the value of backupage take in count the incrementals? Regards, Laurent

Hello everybody !A few weeks ago, we installed Centreon 21.04 and we started to use it in production.Our Oracle DBA want to check the size of a file in an Oracle Enterprise Server 7 Server. For that need, we installed the linux NRPE3 plugin pack (https://docs.centreon.com/current/en/integrations/plugin-packs/procedures/operatingsystems-linux-nrpe3.html) and use the service template “OS-Linux-File-Size-Generic-NRPE3-custom”. If we check the size of the file our dba want to, the state become UNKNOWN “ Command error: du: cannot access 'filepath': Permission denied“ (Filepath = the exact path of the file I don’t want to share here ^^).We have the same result for any files or directories in the monitored server except one, “/etc/nrpe/centreon-nrpe3.cfg”. When we check this file, we have the size of this file as result so the check works for me.On the monitored host, we tried to change the “nrpe_user” and “nrpe_group” options to “root” instead of “centreon-engine” in the file centreon-nrpe3.

Hello,When you want to use the templates in the configuration of a host, you have to click on the "Create Services link et to the template too" button.I found an article from 2015 in French from a blog: https://blog.zwindler.fr/2015/04/18/centreon-hostgroups-modeles-dhotes-la-reponse-de-centreon-a-mon- item/Is the solution given at the time still the same? I am using Centreon 20.04.Thanks in advance

Hello,When I export the configuration of a Poller I get some Warnings about services.  Is there a log where I can see which Hosts those services belong to? I have many services with that description.Thanks.Best regards.

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'=

Hello,Is it possible to have a blog post or a The Watch post about the usage of the --pass-manager options, and is possibility of Password Manager (KeePass, Teampass, Hashicorp Vault) as a security best practice, linked to the usage of the event handlers with the centreon-plugins like Ansible and/or Ansible Tower openning the possibilities of auto remediation usage with Centreon ?Regards,Greg

Is is possible to use unattended.sh to install a remote server?https://github.com/centreon/centreon/blob/develop/unattended.shReading both documentation and code, I see one difference:During web installation, it is not necessary to install Autodiscovery module:https://docs.centreon.com/current/en/installation/installation-of-a-remote-server/using-packages.html#web-installationIn the code, I see ‘process_step8.php’ with something about Autodiscovery:https://github.com/centreon/centreon/blob/a609307ce94937b06157f479b66a14ae5ec465bf/unattended.sh#L647There are other difference or attention point?

Hello, I have a question about graphics. We have set a retention on the 7-day charts.When the graphs are powered with data, we have our 7 days of data. However when we stop the power, we find ourselves with our 7 days of data which shifts in time !Example : I would have thought that the graphic would have been completely deleted after 7 days ! Is this normal working? or I have a problem on my platform?Thanks You :)

Hello , I think createrepo --update is missing for 21.04 plugin repo , can you proceed , all new plugins are not available  Thank you 

This might be a silly question, but we are trying to get permissions working with AD groups. We’ve got everything setup and if we add by user account everything works fine with the Access Groups, Resources, etc.. However if we try and add a AD group, no one can login. I’ve tried many different combinations and locations where to add this group but nothing seems to work. I assume based on the Users, and the filter string that groups do not work, is that correct? Or is it something I am just missing on how to assign permissions to AD groups?Thanks in advance, Matt

Bonjour,Je suis en train de tester des plugin packs sur mon serveur de test, jusqu’à hier tout marche bien.Mais depuis ce matin j’ai un problème étrange en modifiant un hôte ou un service. En fait si je clique sur “sauvegarder” après avoir modifié la conf d’un service ou d’un hôte, j’aurai un écran comme ça :Par contre je peux modifier les conf de “Notification”, “Utilisateurs”,etc. Ce n’est que la conf dans la partie “Service” et “Hôte” qui me pose problème.Est-ce qu’il s’agit d’un problème niveau BDD?Merci d’avance.

Bonjour,Ma question n’est pas directement liée à centreon mais je pense pourra aider les non expert de Centos.J’utilise Centreon 21.10 (ISO 21.04 de base).Il y a quelques mois j’avais réussi à installer phpmyadmin non sans mal …En utilisant les packages rh-php73 etc… j’ai supprimé php 7.3 depuis, j’avais plusieurs versions de php en fait. J’avais du mettre une conf php ici : /opt/rh/httpd24/root/etc/httpd/conf.d sinon phpmyadmin ne marchait pas. J’aimerais éviter d’avoir de nouveau plusieurs versions de php.Tout semble fonctionner normalement, je suis en php 8, sauf que phpmyadmin n’interprète plus le php (page blanche, juste le html)Comment faire pour que phpmyadmin trouve php correctement ?Merci
