System: Log Server 2015R2.2 on CentOS 6.7 (from image)

Issue: Alerts don't run automatically

Guys/Gals,

I've created a few alerts from dashboards within the log server. However even though I specify a interval of 5m and a lookback of 5m the alerts never seem to run themselves. The Last run time never changes unless I choose to manually run the check now. Any ideas what I could be doing wrong?

What timezone are you in? I'm currently exploring an issue that may affect alerts while using the 'JST' timezone.

Otherwise, this could be related to the jobs subsystem.

Try restarting crond on your servers: Give the jobs a reset: Are any of your other jobs not firing, or is it your alerting functions exclusively?

Thanks jolson,

It appeared the alert service hadn't run since 8/14. But all the rest of them looked fine. I'll let you know in a few if the alerts ran or not.

Sounds good, I'll standby for your response.

Perfect! worked great.

Any idea why the job would have been suck, or anything I can do to prevent it in the future?

Also I forgot to answer your other question. I'm in the Eastern Standard Timezone (EST/EDT)

Typically jobs don't stick randomly - was there anything that you were doing in particular that might have caused the subsystem to freeze up? This might include disks filling up, server restarts, or instance outages.

Thanks for the information - there's no evidence of the JST problem affecting US users. I'm still working on debugging exactly what the problem is for the JST timezone.

I've restarted the server manually. But that's about it.

It's possible that your server restart may have caused the jobs to freeze. Does the server restart time line up with the time your alerts stopped running?

It does not appear so.
