This post will describe the process I […]

Sending email from syslog events

Posted on

Historically, I have been monitoring my F5 devices using syslog and Zenoss. Syslog on the F5 devices forwards to my Zenoss system, which then parses the alerts by severity, source, and regex string comparison (node up/node down). My Zenoss system died, so I started looking for other methods of performing the same tasks. Initially I […]
