      2. am I correct by saying that if the Error Log Includes Pattern is unset (i.e. no filtering), everything the the log file will be displayed under 'Event' tab.

      But unfortunately, it's still empty under that tab, despite the Error Log Events Enabled is set to Yes.

       

      3. when I click the 'Configuration' tab, I got a red meesage with 'Show Details' says :

          I have no other option than try to uninventory the agent, an reimport the agent back, but unfortunately I still have the same messages as above.

          Last option for me was to reinstall the server by force ( ./rhq-installer.sh --force ), but this also threw exceptions:

            jay shaughnessy Expert

            To be honest, I've lost track a bit of what is happening here.  As for the original post, Are you saying an update to a single Apache Server resource's Connection Settings is being blocked by a Group Plugin Configuration Update?  Or were you trying to perform an update on a group of Apache Servers?

             

            In short, when performing a group configuration update each resource in the group must be updated.  This can involve several agents.  Were all of the agents running and connected to the server?  I don't know the specifics of group update, I would expect that individual updates would fail after some time, but I'd have to look.

             

            Then, you tried to uninventory an Agent and it too was blocked by a Group Plugin Configuration Update?

             

            Finally, you tried to force a reinstallation when you were already installed and running?

              Hi Jay,

               

              Some screenshots may be helpful to explain.

               

              First scenario, highlight 'Apache HTTP Servers', navigate to 'Inventoty' tab -> 'Connection Settings', then modify some settings.

              After I clicked 'Save' button, a green message was displayed with 'Show Details' said:

               

              Message :

              I have no idea what does it mean by 'Current group plugin configuration for ResourceGroup cannot be calculated'

              Is this a harmful message ?

               

              Second scenario, the 'Apache HTTP Servers' still highlighted, then clicked the 'Configuration' tab:
