Nagios Support Forum

We have an existing weblogic monitor that we want to move to Nagios.

Below is an example of the monitor output.

Is Nagios XI able to read/process that output as it is (I'm assuming it can't)?

If not, what changes would need to be made?

What are you actually monitoring? I wrote some documentation on monitoring weblogic not too long ago, and JMX is always an option.

We're monitoring a number of things in the weblogic domain: clusters, JVM, JDBC, threads, JMS, etc.

We'd like to continue using the existing weblogic monitor process and have Nagios process the output file that gets generated.

I was hoping Nagios could use the existing format, or we could somehow modify the existing format to something that Nagios can use.

Nagios uses a plugin system to perform checks. Basically a plugin will exit with a number 0 to 3, and give some text string. That number determines the OK, Warn, Critical, or Unknown status of the check, and the text is just informational. So what you would need to do is write a check to parse that output (possibly using regex) and alert based on that. It's not the hardest thing in the world, but it is certainly not a one-size-fits-all solution.
