Hello everyone,
I am writing to you as a young IT student learning supervision with Centreon 21.10 (IT-100 license) and stuck with a problem I don't understand.
As part of my work, I have to supervise 3 Linux Debian 11 servers:
- An Apache 2 web server
- A MariaDB server
- A mail server with iRedMail
These 3 servers are installed by me.
I was able to add without problems the first two to Centreon with the help of the very well written documentation and the Linux-snmp plugin (and those intended for the various services).
However, the third one has a problem that I cannot explain. It adds itself well to Centreon, is detected as "available" but the ping is marked as "alert" with a loss of 20% while the other values of the linux-snmp plugin remain as "unknown".
Considering that this third server is configured exactly the same way as the 2 others, both at system and snmp service level. The ping is not disturbed when I test it directly via the RHEL terminal (which hosts my Centreon server).
I really don't understand what could be the source of the problem. I attach screenshots of the snmp service and host configuration on Centreon as well as the results and logs.
If someone has an idea to solve this problem, I'm interested 😁
Thanks in advance
