Alert for Hosts not Online

I'd like to know when a series of hosts go offline.  What would be the best SPL to use with something like this? 

Thanks for your help!

Alerting for hosts not available is a common question that comes up on the Splunk Slack Community chat, so much that it has the following templated reply 🙂  The following resources should certainly help solve your problem.

Are you managing these hosts using deployment server?

if yes, you can make use of deployment sever logs. If you don’t see phonehome for last n minutes, you could create an alert.
