    Monitoring An HA Appliance Using Patrol

      Hi All

       

      I am monitoring a service that is running in HA using remote Patrol Agents. The query I have is whether I will be able to monitor the "a" servers primarily and switch the Patrol Agent to monitor the "b" servers if service is switched over. There are a number of processes that will be monitored and will only be running on "b" when service is failed over. If I permanently monitor them it will be constantly in a state of alarm.

       

      Any suggestions will be appreciated.

       

      Many Thanks

          The best way (when possible) is to monitor the servers the same way clients query the HA cluster. Consider you have ha-cluster with 2 nodes (nodeA and nodeB), you'll setup the monitoring to query ha-cluster, rather than nodeA or nodeB. The clustering mechanism will direct the monitoring queries to either nodeA or nodeB, depending on which one is active.

           

          Hope this helps!

            Thanks a lot for the reply. I guess I need a bit more help on how to go about configuring a Patrol Agent to monitor as a cluster. The servers are not in a dedicated cluster but have a rudimentary configuration that starts up the processes on "NodeB" should they stop on "NodeA". How do I get the Patrol Agent to recognise that behaviour?

             

            Many Thanks
