problem with check_snmp on linux
Posted: Fri Oct 27, 2017 5:07 am
On my Nagios XI installation I have received errors from 3 hosts during the last 3-4 days.
The same service checks have been working fine until now.
The same errors appear on all hosts:
- ERROR: Description/Type table : No response from remote host 'x.x.x.x'
(check_xi_service_snmp_linux_storage) several disks
- No answer from host
(check_xi_service_snmp_linux_load) cpu load
- ERROR: Alarm signal (Nagios time-out)
(check_xi_service_snmp_linux_process) different processes
On one of the hosts some other service checks are working fine.
I'm not able to do a snmpwalk to either of the 3 hosts.
Nmap shows filtered snmp.
I have compared to other similar hosts, but I'm not able to see any differences.
Any suggestions what the problem might be?
CentOS 6.9 64-bit
Nagios XI 5.4.10
