Nagios Alerting Issue

[vignesha]

Hi,

In our environment, we have automated from nagios to ServiceNow where if nagios trigger any alerts it will send SNMP trap sender to ServiceNow console and auto ticket will generate automatically and assigned to respective team and we customized to check the alerts from snow console itself to reduce monitoring team work and it was working fine without any issues.

We faced issues in nagios where xxx server scheduled for down time at every Monday 2:05 to next half an hour in nagios and during the recurring down time window server was down and after down time ended also server and services was down and state not changed in nagios, by default alert will came to Operation Screen is the expected and functionality of nagios but the alert haven’t sent any SNMP trap information to Servicenow console post which it got escalated to our team.

When we checked the state history server took 6+ hours to came up. PFA screen shoot

Can you just help me out where this issue can be get resolved in nagios?

Let me know any further details required from my end.

Hello @vignesha,

Let me re-state the problem for clarification. So the service goes into a non-ok state during scheduled downtime and eventually recovers, 6+ hours later. After scheduled downtime ends, notifications resume by Nagios but the SNMP trap was never sent for the service. Is this correct?

In the SNMP Trap Sender settings, did you check Don't Send During Downtime? If you did, uncheck this option.
