Event handler & Downtimes

Hello,We want to use the event handler functionality to do “self correction”.By default, a service exits downtime does not generate any events and therefore is not traced by the event handler functionality.Indeed, a service in CRITICAL state which exits downtime does not generate a new event and therefore cannot be processed.This is our problem, because this service in CRITICAL state needs to be solved!Is it right?How can we do?I guess we are not the first to ask ourselves this question but I have not found a clear answer.Thank you in advance for your answers.Regards,V. Bodin

Automatically add a autodiscovery service rule to a host template

HelloI have a question about the autodiscovery service rules.Does someone know how to automatise the addition of a host template at an autodiscovery service rule? For example, we create a template “OUR-OS-LINUX-SNMP” which is derived to “OS-Linux-SNMP-custom”. If we want to use the autodiscovery service rule “OS-Linux-SNMP-Network-Interfaces” we must add our host template manually via the GUI of the configuration of the service rule We’ll like the equivalence of the command CLAPI to add a service template at a host templateADDHOSTTEMPLATE … but we don’t find nothing about the autodiscovery rulesThanks

HP Proliant 22.07.5 Plugin Pack Installation question - missing /centreon_hp_proliant.pl

I want to monitor HP server via SNMP. On pooler I installed the plugin pack “HP Proliant”.I created new host from template “ HW-Server-Hp-Server-SNMP-custom “ and entered monitored iLO’s  ip address and did pooler export.Now I have This host in monitoring with service “Hardware-Global” that has supposed command line:/usr/lib/centreon/plugins/centreon_hp_proliant.pl --plugin=hardware::server::hp::proliant::snmp::plugin --mode=hardware … etcbut in fact the file /usr/lib/centreon/plugins/centreon_hp_proliant.pl does not exist on pooler and service is in state unknown. Why the file /usr/lib/centreon/plugins/centreon_hp_proliant.pl was not created by pluginpack installation?

Standard macros

Hi,The Centreon documentation about standard macros links to the Nagios documentation. Does it mean we can expect all those macros to be present in Centreon, and none which would exist in Centreon only?If this is not the case, where can we get a complete list of them with a short description?If we want to test the macro, does creating an ad-hoc command to do so the best way to obtain this information? (it would not suppress the need for a list, to know what exists and what not)I didn’t check the source though, it probably is possible to get the information in the Centreon Engine source code? Is it easy (ie: clearly visible, not lost in the middle of many lines of code)? Could someone get me a link to the best place to look for this?Have a nice day.

How to connect commands in Centreon?

Hello,I have the following problem. I would like to monitor the incoming traffic of an Aruba switch. There is no template for this. However, I have the OIDs for ifInUcastPkts, ifInMulticastPkts and ifInBroadcastPkts. For the command I would use centeon_generic_snmp.pl for each OID and then calculate the sum. However, I don't know how to set this up in Centreon.

Security fixes, communication must be improved.

Hello,I you like to share my thought about the 2 last releases who fix critical security hole.I’m not satisfied how the communication is done on security point like this. I discovered the problem with this post from the french CERT : https://twitter.com/CERT_FR/status/1743295694113309077 For a problem like this, the only information I find washttps://thewatch.centreon.com/product-updates/security-bulletin-for-centreon-web-2807witch is now 14 day logs, and since this post a new release for another security hole was published, without any changelog.And who goes everyday on TheWatch to see if security fixes was published ?! Most people on your Slack did not even know that theses security hole/fixes was published.For the last release I tried to get information about what was changed on X and Slack, nobody respond. I think you must inform your customers widely for such security updates :E-mails, your Slack, your X (twitter) account, the website homepage, home of the documentation,…Having se

REMI PHP repository for Centreon

Hi,I wonder if the “remi” repository is mandatory or if the “remi-safe” suffices? The documentation states “remi” but if “remi-safe” is sufficient we’d better use this one.And what’s about “remi-modular”?RHEL 8

Can't connect poller to central server

I am trying to connect a poller to a central server and I am having problems.First of all I have to set the -insecure flag because otherwise it tells me that it cannot connect to the central server. I guess it is because it is a self-signed certificate, although on the web I get that "the certificate is valid and signed by an authorizing entity". I get the error:ERROR - https://ip_central:443: {"message": "No parent platform was found for : 'POLL01'@'local_ip'"}I have checked with telnet to the central server and port 443 that it can connect. I also have gorgoned and the other services active in the poller.Any idea what it could be?Thanks!!
