Alerting

Alert when service is down on multiple hosts

I have the Splunk Add-On for Linux and Unix installed which enables the "PS" command. How can I monitor the tomcat service or some other service on multiple hosts for 5 minutes?

This is what I have so far:

host="server-*" source="ps" tomcat

I would like to trigger an alarm whenever the tomcat service has been down for more than 5 minutes on any of the hosts that the query finds.

Try the following search:

host="server-*" source="ps" process_name="tomcat" | dedup host | eval lastseen=now()-_time

You might need to change process_name="tomcat" to suit your needs. You also might want to add "index=..." This will make your searches faster.

Save this search as an alert with the custom trigger condition: lastseen>300. The time range should be several hours, e.g. last 24 hours.

when you say "You also might want to add "index=...""....

This means setting up a monitor this way:

splunk add monitor /opt/tomcat/logs/catalina.out  -index tomcat

Right?

and then do:

 host="server-*" source="tomcat" process_name="tomcat" | dedup host | eval lastseen=now()-_time
