    Periodic down alert Agent 1.2 beta 1 server 2.2

    swapnil yeole Newbie

      In Jopr server Jboss instance goes down after approximate 59 to 60 min state down for 1 min and agene come back. This behavior is seen in only one server. All other are working fine.
      I tried to remove this jboss instance form monitoring but it came out with some error now I am not able remove it from inventory. i took every possible action which I can but no help.
      Env :
      windows server
      Jboss configured as windows service with jboss-native
      Java : jdk1.5.0_14
      After enabling debugging mode in Agent I got these error:

          I don't know what the problem is specifically but I can tell you the following:

          1) you say something happens every "59-60 minutes". By default, every 60 minutes the agent will ask all resources for their configuration and if they differ from their last known config, the agent will tell the server someone changed the resource config. See this flash demo for why this config-change-detection is a useful feature: http://management-platform.blogspot.com/2008/12/configuration-change-detection-in-jopr.html

          2) the exception you get is probably part of this config check I mention above:

          2009-03-23 16:31:02,262 WARN [ConfigurationManager.threadpool-1] (rhq.core.pc.configuration.ConfigurationCheckExecutor)- Unable to check for updated configuration org.rhq.core.pc.inventory.TimeoutException: Call to org.rhq.plugins.jbossas.JMSComponent.loadResourceConfiguration()
          


          Notice it says, "unable to check for updated config" - this looks like that hourly config detection check. But your JMS resource is not able to load the configuration in a timely manner and thus you get a timeout exception. I don't know why this happened, but its possible that when this happened, your JBossAS server would have then been considered DOWN.

          Perhaps find out if this resource-change-detection is putting too much load on your JBossAS server and causing it to respond very slowly and look DOWN to the agent.

            Hmm... for some reason, that flash demo is missing from redhat.com. I'll ask around to find out what happened to it. But that blog entry talks about this config-change-detection stuff.

              Thanks for the quick response.
              I to don’t know what’s wrong with this server, to test anything any possibility I have to wait till 2 hr,
              I don’t have proper error no where not in jopr server / agent and jbossAS. I don’t know how to solve this.

                My bad luck this time everything go’s fine and it haven’t went down. While discovery processor just spice to 100%, JbossAS was just fine. Could this is something to do with “Messages Driven EJB� this is the only partially down in this instance(Audit & SME) is working fine but some of them are red with the same name
