    Incorrect Max Heap displayed

    ssroy73 Newbie

      Hi,

       

      We have set MAX heap of 256M in Jboss. The same is visible in JBoss JMX-Console also. But when I look at the same value from RHQ, it shows me zero. I have attached snapshot of both. The same happens to 'Total Memory' as well.

       

      Any hint will be greatly appreciated.

       

      Thanks a lot.

       

      Best Regards,

       

      Roy

          Noticed few exceptions in agent.log. PSA the same.

           

          Thanks a lot.

            Is that metric disabled? What's the collection interval if its enabled? Did you wait long enough for that collection interval to expire before checking the metric value?

             

            Go to the Measure>Schedules subtab to check these things.

              Hi John,

               

              Thanks for reply.

               

              These metrics are enabled and I had changed the collection interval at 30s. I waited for long time but its still same.

               

              Its showing value for 'FreeMemory' but this is not matching with the value I can see from jmx-console. But 'ActiveThreadGroupCount' shows same both in jmx-console and RHQ.

                  The first is probably due to your Apache's SNMP module responding too slowing for requests for SNMP data. RHQ agent plugin is asking Apache SNMP module for data, and the request is timing out.

                   

                  The second I'm not familiar with because I didn't write any of the Apache/Augeas stuff - but the error message seems straight forward You must have Augeas installed for RHQ to manage Apache configuration (we use Augeas to read/write the apache configuration files) and you must have Apache 2 (not Apache 1). Again, I'm not familiar with this code, I only deduced this from the error message.

                    Regarding Timeout --> Is there any way to increase it.

                     

                    Apache --> We are using Apache 2.2.15

                     

                    Augeas --> I have installed Augeas in my system but getting the same error

                     

                     

                    Thanks & Regards - Roy

                      To be able to configure Apache, make sure to enable Augeas in the connection properties of the apache resource. The property is called "Enable Augeas support" and it is off by default.

                       

                      Also you don't have to have augeas installed on your system, because it is bundled with the agent. The agent always uses it own copy of the augeas lib regardless of the version installed system wide.

                       

                      The error message is after all slightly confusing..

                        Thank you very much.

                         

                        Both exceptions have disappered now after setting the value to "true".

                         

                         

                        But I am still getting Max Heap as zero in the graph where as in Jboss JMX-console (jboss.system:ServerInfo), I can see the value of Max Heap as 256.

                         

                         

                        Any hint will be greatly appreciated.

                         

                         

                        Thanks a lot.
