    Is it possible to monitor each web service method using JON

      Hi There,

       

      We want to monitor each web service method using JON. Please let me know if this is feasible. If yes, what are the steps.

       

      Thanks a lot.

          One way you could do it is with the netservices plugin:

          I'm not sure if it fully supports the different HTTP methods (GET, POST, HEAD) but I bet the code could be enhanced easily for that. Code contributions are welcome!

            Thanks a lot John.

             

            I installed the plugin where agent is installed. The same is also visible from administration > Agent plugin screen. But I can't see any metrics around this listed anywhere. Will really appreciate any clue.

             

            Thanks a lot.

              Did you manually add your endpoints? Because the agent won't be able to auto-discovery any endpoints that you want to monitor (what algorithm could it use to know what endpoint (URL with host/port) you actually want to monitor? - they technically could be anything, anywhere on the 'net).

               

              So, you'll want to go to the GUI, navigate to the platform for your agent and view the Inventory>Children page (I think that's the name). From there, manually add a "HTTPService" or a "PingService" object and follow the screen instructions. See this blurb from the online docs: https://docs.jboss.org/author/display/RHQ45/Inventory#Inventory-Manualdiscovery

               

              If I may hedge my bets here - I can't vouch that this plugin works well. However, the descriptor shows these metrics the HTTPService "should" be collecting:

               

                      <metric property="connectTime" units="milliseconds" displayType="summary"
                              description="The time to connect to the service"/>
                      <metric property="readTime" units="milliseconds" displayType="summary"
                              description="The time to transfer the requested content"/>
                      <metric property="contentLength" units="bytes"
                              description="The size of the returned content"/>
                      <metric property="contentAge" units="milliseconds"
                              description="The declared age of the requested page"/>

              The PingService is very limited in what it collects (all that does is verify the endpoint is reachable).

               

              I suspect this plugin may need additional code to flesh out its capabilities. It was a prototyped contribution and I can't say much of any testing went into it. This is why I kind of seem like begging to get someone in the community to work on it
