Monitoring Log Files - /var/log/maillog in this case
I'm still learning about hyperic features and I have a question about log monitoring, which I've done very little of.
Previously, I've only set up log monitoring on a Windows platform to watch the Syslog for specific entries. It worked. Now I've been asked to setup monitoring on a redhat linux platform with PostFix mail service running on it. I created an SMTP platform service on it, looking at port 25 on localhost. It reports availability and response time (ms) by default and this is working fine. I was asked to watch /var/log/maillog for specific error messages. I can't find in the documentation how to do that.
The link for oracle doesn't exist anymore. I searched Google and these forums and can't find a "how to" on how to write an expression for the Log Pattern Match field. Has anyone done this? Do I watch this log at the platform level or the smtp platform service level? Is there more documentation somewhere?
