I’m running Icinga2 v 2.5.3 with Director in a distributed top down configuration. All is working mostly well. I’m seeing some sporadic issues with only one of my check commands and it seems to be limited to a few systems…
The check command script is check_snmp_win.pl. For a few systems on which i’m monitoring multiple services, I sporadically get “Process name table : No response from remote host…” The service checks change from OK to UNKNOWN to OK repeatedly. They only remain UNKNOWN on average 5 minutes or so. This seems to happen for all of the services being monitored but not all at the same time.
Could there perhaps be some SNMP settings on these few systems that are not properly setup causing some requests to be ignored? I’m using SNMP for most other checks like CPU, Disk, memory and I don’t have this problem with any of those checks. So if it was SNMP related I think the same issue would occur with these other checks but this is not the case. It only happens with these service checks.
Any help/tips would be appreciated. Thanks.
