Centreon Infra Monitoring

Hi,I have for a couple months now had issues mainly with the hosts and ICMP. Hosts are pinged every minute to get the UP/DOWN status. I’ve noticed that every other ping is basically failing in a “CRITICAL”. I have tried manually to ping some of these hosts from the same server and there are no network related issues.The issues seem to mainly be related to performance. For services UP/DOWN these checks work better but they are scanned every 5 minutes.Occassionally there can be a PROCESS TIMEOUT. I’m running centreon 24.10.25 on Debian 12 with 4 vCPU and 16 GB memory.We have 478 hosts in our centreon environment and 2052 services. This is running on one cenral poller.I’m thinking about setting up one more poller to see if it might solve things.The “tuning” tab on the engine configuration looks like this. Engine statistics:  

Hello,We have on prem centreon 23.04 and I need to install the Monitoring Connectors1) F5 BigIP SNMP which brings this host template in Centreon so I can monitor F5 network devices: Net-F5-Bigip-SNMP-custom and  2) X509 Certificate which brings this host template in Centreon so I can monitor certificates in format .pem and .der :App-Protocol-X509-custom .tried multiple links but not working https://plugins.centreon.com/ https://marketplace.centreon.com/ and I need them to be .rpm files on redhat to manage the installation on prem.Can you please help  me with an available location to download them  ?

Hello, Just a note that recently the unattended script on page https://docs.centreon.com/docs/24.10/installation/installation-of-a-poller/unattended-install-poller/ as step 2 for installing 24.10 pollers:curl -L https://download.centreon.com/24.10/unattended.sh --output /tmp/unattended.sh is throwing HTTP 404 and downloading the HTML error page instead.URL: https://download.centreon.com/24.10/unattended.sh In my opinion, it would be better for these pages to either:if this situation is unavoidable, return HTTP 404 status without returning a human readable document, instead of whole HTML to be pulled and executed blindly on other people’s servers, return a script that echoes “sorry we pulled the script for maintenance, try again later”, or joining lines 2 and 3 using && operator to avoid executing the error page.  Thank you. 

Pour une supervision sur des serveurs windows avec CMA, pourquoi centreon remonte des chiffres en PetraBytes ou ExaBytes lorsque l'occupation du swap augmente alors que la taille qui lui est alloué n'est que de quelques Giga ?Merci d’avance !

Hello, just here to share to the community an issue that i encountered, the underlying issue, and how it can be resovled.This happened on a quite heavily loaded central server (poller included), and my end users reported receiving load of emails alerts regularly, but during bursts of a few minutes.After investigating the commands failing, there was nothing to correleate them, any service could fail, and all failed with the same output: “Execute command failed”. Something strange was at work here.After going more in the logs, especially centreon-engine logs, i find it. “Too many open files”. Here is the issue.At first i supposed there was permissions issues or something, but this is irrelevent as all can happend to any commands usually working fine. So i dig deeper on the internet, and here i find it, the Linux File Descriptor Limit. cyberciti.biz - linux increase the maximum number of open files . This limit by default is around 1024. I then do a quickls /proc/[centengine_pid]/fs/*and

Hi,I don’t know if it changed recently or if it has always be like that, but I noticed the following: if --expected-content has a value, then --critical-content is ignored. It means, if one want to check both a return code and the presence of a string in the page content, one should not use --critical-content=’ %{code} != 200 and %{code} != 401’ --expected-string=foo (because then only the presence of “foo” would be checked!), but what must be used is  --critical-content=’ %{code} != 200 and %{code} != 401 or %{content} !~ /foo/mi’.Is it something that changed recently? Is this something reliable (ie: it won’t change in the futur) ?

Hello.Is there a plugin that can be used to get the DNS zone expiration from SOA?I have tried with the DNS Service connector, using --mode=request --search-type='SOA' but it doesn’t show the complete SOA. With --verbose or --debug the result is the same, only the response time.Regards

Hi guys,I need Help to change data collection from poolers.I mean in my configuration all poolers should communicate with the main Centreon Engine 23.04.4 via VIP address. But for some poolers after a reboot of main Centreon server they are sending data directly to Centreon servers without passing through the VIP and until now I didn’t find how or where to force the pooler to communicate only with the VIP.Can you please help me in this case ?

We are experiencing an issue after upgrading Centreon to the latest version. We recently upgraded our Centreon platform to the latest version 24.10.27 and have observed an issue affecting multiple monitored serviceSince the upgrade, several services that were previously working correctly are now reporting an UNKNOWN status.The plugin output reported for the affected services is: - UNKNOWN: No locks counter found with given filters- UNKNOWN: No locks waits counter found with given filtersWe would like to understand if:- There are any known issues after upgrading Centreon that could cause services to return UNKNOWN status.- Any plugin changes or compatibility issues introduced in recent Centreon versions could explain this behavior.- There are any known fixes or troubleshooting recommendations for similar cases. Any guidance or suggestions would be greatly appreciated.

Hello users and maybe Centreon team.I was having a thought.Now that there is a multiple ecosystems around Centreon like Centreon Experience or Log management, there is a component called User Portal to manage common configurations between services.This makes a lot of sense, but here is something that confuses me.Right now within Centreon if you want to create dashboards about coordinated data, you need to extract partial data from those tools to Centreon Infrastructure Monitoring (so they can be historised) and then within that tool create dashboards.Wouldn’t it make sense to have some kind of Historisation / Dashboarding solution on TOP of all the existing components ? I suppose that’s for historical reasons (as all started from that component), but as the ecosystem evolve i’m questionning myself. This is close (in my opinion) to what is intended behind the BAM module where we aggregate multiple technical sources to give business views, but having to do that within the Centreon Infra

HelIo,would like to monitor my Exchange servers using Centreon Monitoring Agent, but I am using the free version.Is it possible to create the commands manually?Cordialement;

Hi,We are starting to look at the new version of Centreon (25.10.10) and would like to set up some custom views.Looking online. I can see that Custom views are hidden by default, and that there is a manual process to enable them, but I can’t find out what that process is.Can anyone help?Thanks,alamb200
