How to manage access by membership in Active Directory Groups?

Currently we have a working LDAP connection to our AD but we import users manually and remove them manually when access should be stopped.This is a certain administration effort, the only advantage is that users can user their AD credentials to authenticate.  Target is to manage user access to Centreon only in AD, e.g.,all members of the AD group Group_A should be member of a certain Centreon contact group, e.g. “Admin” all members of the D group Group_B should be member of a certain Centreon contact group, e.g. “ReadUsers” …When a user has been removed from the corresponding AD group access to Centreon should be removed automatically.Long story short: Centreon access rights should be managed fully in AD without need to manage users in Centreon. Is this possible? Official documentation is not very helpful (https://docs.centreon.com/docs/administration/parameters/ldap/).For me this seems to be the standard how authorization should work. I searched in TheWatch as well but I did not found

Trying to install nagios plugins from old github repo

Hello, so I was configuring a new centreon solution manually and in a command check called: OS-Linux-SNMP-Traffic-If-SpeedI found the following command:$USER1/$/check_centreon_snmp_traffic -H $HOSTADDRESS$ -S --snmp-version='$_HOSTSNMPVERSION$' $_HOSTSNMPTRAFFICEXTRAOPTIONS$ -i '$_SERVICEINTERFACENAME$' -n -w '$_SERVICEWARNING$' -c '$_SERVICECRITICAL$' $_SERVICEEXTRAOPTIONS$however, I didn’t know where to find “check_centreon_snmp_traffic” file so I’ve looked online and found this github repo:centreon-plugins/src/check_centreon_snmp_traffic at 7bd0a4bd38bb7f9ce7be15b1a0efd045245b4a84 · centreon/centreon-plugins · GitHub And it contains the file, so I’ve followed the insctructions on the read me file, aka:- just run install.sh in src/ directory- don't directly copy plugins in Nagios plugins directoryand I did just that, I downloaded the whole directory, and I tried running the ./install.sh file, however I got this error:I’m guessing ebcause the “functions” dir doesn’t exist but I’m not

Compte AD bloqué après une seule tentative de connexion / AD account locked after one try

=============================================================================================== ENGLISH (FRENCH BELOW) ===========================================================================================Hello,I expose my problem here hoping to find some help...I noticed a rather strange behavior on my Centreon, I connect via LDAP.If I make a single login/password mistake, my AD account is instantly locked.On the AD side, the locking policy is 3 attempts and the problem is only encountered with Centreon.Real example:Here we can see 3 attempts with failure, except that I tried to connect only once.As if Centreon retries several times by itself? ==================================================================================================== FRENCH ======================================================================================================Bonjour,J’expose mon problème ici en espérant pouvoir trouver de l’aide…J’ai remarqué un comportement assez étrange sur mon Centreon

The server returned a "500 Internal Server Error" on Hosts page

Hello the Watch,We have just updated our centreon server and poller (OS alma linux 8.10) from 22.10 to version 24.10.7 and we have some issues now when we try to access the Hosts config pages: “Oops! An Error OccurredThe server returned a "500 Internal Server Error".Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.”It looks like a PHP error...Otherwise all the services are fine, restarting the collectors show no error.I think I may need to create a new server from scratch, install a fresh centreon and then migrate the configurations… but hopefully there is a better workaround ?Can you please help us with this issue ?Respectfully,

Memory and CPU usage of a Cisco CBS350

Hi everyone,I’m encountering an error with the centreon_cisco plugin while trying to monitor memory usage on a Cisco CBS350 switch (firmware version 3.4.0.17): UNKNOWN: Cannot find memory informationsHas anyone experienced this issue before? If so, are there known workarounds to retrieve memory metrics?Details: The plugin fails to fetch memory data via SNMP. A custom script workaround might require privilege level 15 (full admin access), which is restrictive. Questions: Is there a specific OID for memory monitoring on CBS350 switches running firmware 3.4.0.17? Are there alternative methods to monitor memory without requiring privilege level 15? Any insights, scripts, or configuration tips would be greatly appreciated!Thanks

Monitor web page return code

Hi,I am trying to add a check on a web page to ensure it is up and running. I tried with the HTTP plugin with the HTTP-Response-Time service template. By default it will fail only if the web server is not responding but it will be OK even with a 404 error for exemple. So I guess I have to use the option --critical-status to check that return code is 200. This gave me the following command/usr/lib/centreon/plugins//centreon_protocol_http.pl--plugin=apps::protocols::http::plugin--mode=response--hostname=myhostname--proto='https'--port='443'--urlpath=''--warning=''--critical=''--http-peer-addr='my_web_page_url'--critical-status='%{http_code} != 200'However when the web page URL returns a status different from 200 the test is still OK.I guess I should use a different syntax for the --critical-status parameter? But all the exemples I found refers to this syntax.I might have to use a different plugin or template to do what I seek? But I could not find which one then.Your help or comments are

How to use SNMPv3 monitoring plugins in Centreon Open Source (without license)

Hi everyone,I'm using the open source version of Centreon (no license, no commercial subscription) and I would like to monitor equipment like Cisco switches, HP servers, UPS, PDUs, etc. using SNMPv3.I know that with a commercial license, I could simply use the Monitoring Connector Manager to install packs like network-cisco-standard-snmpv3, but in the open source version, only basic modules are available and the rest require a license.That said, I was able to install centreon-pack-operatingsystems-linux-snmpv3 via APT, and it works perfectly for Linux hosts using SNMPv3. So I assume it's technically possible to use SNMPv3 monitoring for other devices as well, but manually, without licensed packs.I’ve already cloned the official centreon-plugins GitHub repo and I can run checks via CLI successfully. How should I configure them properly in the Centreon web interface (host templates, service templates)?This is part of a large-scale migration from SNMPv2 to SNMPv3 across many existing devi

Confused About Monitoring Connectors, Plugins, GitHub Repo & Licensing

Hey everyone,I’m setting up Centreon and I’ve hit a point where I’m confused about how Monitoring Connectors, plugins, and the GitHub plugin repo all relate — especially when it comes to licensing and offline environments.Here’s my current situation and questions: After a fresh install of Centreon, I could install some Monitoring Connectors (I think these are the default/free ones). But I also see many others greyed out — I assume those require a license? I understand that Monitoring Connectors (or Plugin Packs?) are templates that help configure services, but I’m not sure how they relate to the actual plugin scripts (like those in /usr/lib/centreon/plugins/). I also don’t really get the relationship with the GitHub repo (https://github.com/centreon/centreon-plugins). Can I just clone that repo and use it without a license? if I clone it will i be able to use all plugins and won’t need to install connectors/packs etc? If I do clone the GitHub repo, should I clone it on the Centra
