Hi,
Following the migration of our Centreon server from Alma 9 to Debian 12, we are experiencing consistent timeout issues when monitoring a Windows VM and a storage array.
The Windows VM has refused to respond correctly to requests since the migration:
NRPE (Job-Status): The NRPE version ping works remotely (‘I (0.11.8 2026-01-24) seem to be doing fine...’), but as soon as I call a script, I get a ‘Process Timeout’ (and ‘0 bytes received’ in the CLI). However, the centreon_plugins.exe plugin runs fine when launched locally.
SNMP side: Windows SNMP check commands consistently time out when run from Centreon:
The Swap service reports: UNKNOWN: SNMP GET Request: Timeout
The Memory service reports: UNKNOWN: SNMP Table Request: Timeout
sudo -u centreon-engine /usr/lib/centreon/plugins//centreon_windows_snmp.pl --plugin=os::windows::snmp::plugin --mode=swap --hostname=IP --snmp-version=“2c” --snmp-community=“public” --warning=“80” --critical=“90”
The storage array and the Hardware services (CTRL1 and CTRL2) also report: UNKNOWN: SNMP Table Request: Timeout.
However, the IP address of the new Centreon Debian 12 server has been successfully added and configured in the array’s authorisations (public community).
Thank you in advance for your help.
