    JON server availability monitoring

    montblanc

      On my system it takes JON about 5 minutes to update the availability status of the JBoss EAP server instance for shutdown and start operations. Once I start the server via JON and startup completes, it takes an additional 5 minutes for JON to show that this new instance is up and running. Same for shutdown.

       

      Is this configurable? I can't find it in the docs. I would like this to take no longer than 10 seconds.

       

      Setup:

      - RHEL 5.5 on x86

      - JON 2.4 GA

      - JBoss EAP 5.0.1

      - Sun JDK 1.6

      - both JON server, agent and JBoss EAP are on the same host

          Hi Roman,

           

          you can tune this in the agent properties file, *but*

          - less than 1 minute makes no sense as this is a global value and thus increases the load on all managed

          resources and also the server

           

          We are thinking of allowing to define selective availability reporting intervals in the future, so that you

          can define e.g. the AS itself is polled every minute while e.g. some less important server is polled

          every five minutes.

           

          If you want to help implementing this (or "just" tell us your requirements here), ping me or post in this

          forum.

            Thanks for the clarification! I should have looked more closely at the agent congif file. I now see the property:

             

            <entry key="rhq.agent.plugins.availability-scan.period-secs" value="300"/>

             

            When I change this to "10" seconds (instead of 5 min) it does seem to update the server status much quicker.

              Oh yeah,

              wanted to include that property in my post, but got sidetracked :-/

               

              Good that this works for you - you may nevertheless closely monitor your systems (including RHQ server) if this does not impose a too heavy load on them.

                When you get the monitoring data, how to get the report on the data?
