SSH persistent connections

Hello everyone,I am currently using the Centreon plugin, `centreon_linux_ssh.pl`, which generates multiple SSH connections for each service that is being executed.I am wondering if there is a way to establish persistent SSH connections instead.I noticed that there is a Centreon SSH Connector but But isn't it deprecated.? https://docs-older.centreon.com/docs/centreon-ssh-connector/en/latest/Is it possible to achieve this functionality directly from the Centreon Engine ? xy

[LDAP] Group membership set to default when syncing at login

my users are members of A LOT OF GROUPS, so I tried to configure a LDAP filter in the Group Searchex:GROUP FILTER -- (&(ObjectClass=Group)(sAMAccountName=%s)(sAMAccountName=XXX_*))GROUP MEMBER ATTRIBUTE -- memberUSER GROUP ATTRIBUTE -- memberOf It works well when I import a user, the groups assigned are correct, only groups starting with XXX_ are shown in the GROUP LDAP and LINKED TO CONTACT GROUPS  But when the user logs in the LDAP sync occurs, it takes a VERY LONG TIME and all the LINKED TO CONTACT GROUPS is replaced with all the memberships from the Active Directory.New values retrieved from LDAP Group Ldap same as after importIs there a way to keep the synchronization filtered ?

Alert notifications per user

Is there a way to make alert notifications per user? That is, only one slack channel is notified (for example, in my case I use slack) of all alerts from hosts/services to which a given user has access.

Special character service monitoring

Hi,I am monitoring the services of a server, but it has in its display name, special characters like “ç” and “~” and when I ask to verify the service, it gives the PROBLEM error, which is its way of saying that it did not identify the service.I managed to monitor other services on the same server, but these services did not have a special character.Any tips on how to make centreon identify these special characters?

Prometheus expression : always "no expression found"

Hi,I try to use the prometheus expression plugin.First, with a basic query for load average 1m. Whatever I do, I always get the same result: UNKNOWN: No expressions found.Command:/usr/lib/centreon/plugins//centreon_prometheus_api.pl --plugin=cloud::prometheus::restapi::plugin --mode=expression --hostname=xxxxxxxx --url-path='/api/v1' --port='9090' --proto='http' --query='cpuload1m,node_load1{job="node-exporter"}' --output='%{instance} load 1m: %cpuload1m%' --instance='node' --use-new-perfdata --verboseNo alert for now, i’m just trying to view the result.What is curious is that in debug mode, I have the desired result, but with the same error message no expression foundWhat am I doing wrong ? I have a lot of metrics to do, and even the simplest one doesn't work, that's promising 😯 Thanks

We didn’t find a plugin that can connect Centreon with Gitlab.Is it possible to create alarms in Centreon through API calls ? Is there another alternative to do so without API calls ?We’re using Centreon 2.8.23

What Monitoring Connectors need a SNMP version 3 template?

Dear Watchers,As I said here, we experimented a new SNMP version 3 template for Linux.We are planning to add similar SNMP version 3 templates to other monitoring connectors to make it easier to use SNMP v3 (I agree it's not ideal to use the $_SERVICEEXTRAOPTION$ macro for that) in more contexts.What I'm proposing you here is to answer to my post by giving:The name of the monitoring connector or the host template you'd like to see support SNMP v3 macros. The desired security levels (noAuthNoPriv, authNoPriv, authPriv).Then we'll prioritize the posts that will receive the highest number of "thumbs up" to deliver new templates in the monitoring connectors.Can’t wait for your suggestions!PS: If what you want is a template that do not exist yet as a monitoring connector, then please use the ideas section!PPS: Please post only one suggestion per post 🙏🏻

Execution of shell shell scripts by Centreon Engine

 Hi,We often get issue with custom plugin (or event handlers) implemented in Bash as the behavior between running them manually from the shell behaves differently of when they’re run by the centengine process. I guess this is a normal behavior and related to the login/interactive nature of the shell, which differs in both cases.Does someone is able to bring some precision on the method centengine uses to run the commands?I’m not sure to understand the meaning of the following option in command configuration (picture pasted at the end of the post because it seems I can’t move it between text blocks):Does the description mean it has no influence when using Centreon Engine?Does centengine force the shell to be interactive (and thus loads some environment of the centreon-engine user? Or does it set some variables independently? What else?I have to run some tests but I’d like to ask here if someone has any clue. Some users in our company have observed difference in the $PATH value between a
