Do we have any default health check mechanism using which we can configure and monitor the health of a cluster?
Can you elaborate more on what would such mechanism look like?
- If you were to monitor a set/cluster of AS, you would typically set a monitoring system such as nagios or RHQ.
- The cluster itself performs a health checks (FD protocol), you will see information in the server log.
Also where can I view all the nodes in a cluster?
E.g. via JMX. In JConsole that would be MBeans -> jboss.infinispan -> CacheManager -> web -> Attributes -> ClusterMembers
Thanks for the reply. As an administrator, I would like to know what all nodes in the cluser are present, how many are active. So that I can act accordinly and take a corrective action. What if all the nodes in the cluster went down? I know weblogic provides a self health monitoring of the multiple clusters. I was expecting soemthing similar on the same line.
