Alerting Not Running

I have two alerts setup in Nagios Log Server to run every 5 minutes (5m). However they don't appear to run by themselves as their last execution date shown is when I ran them manually. Crond is started on the backend. What should I look at from here?

Can you post a screenshot of the alerts page? Also did you check the "alert only when critical/warning threshold is met" check box in the alert creation modal?

Yes, Only alert when Warning or Critical threshold is met was checked when I created the alerts. Thresholds were set at 1 for both warning and critical.

Navigate to Administration > Audit Reports
In the table it should show the cron jobs that run on Nagios Log Server. Look for the Alert job- there should be a job run every 20 seconds so it will be very visible. If there aren't any alert jobs in the table at all you might have an issue with the jobs not running correctly.

The job does not exist in the Audit report. How do I go about recreating that job or rescheduling it to run?
Thanks for your help.

Could you run the following from the CLI on your log server and post the output to verify it is missing
Code: Select all
curl -XGET 'http://localhost:9200/nagioslogserver/commands/_search?pretty&q=command:run_alerts'
Thanks!

If the hits comes back as
Code: Select all
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
Run the following
Code: Select all
curl -XPUT 'http://localhost:9200/nagioslogserver/commands/run_all_alerts' -d '{"command":"run_alerts","run_time":1,"frequency":20,"node":"global","type":"system","status":"waiting","active":1}'

"hits" : [ {
"_index" : "nagioslogserver",
