Jboss as 7 Clustering health check

[gaurav80]

Hi,

Do we have any default health check mechanism using which we can configure and monitor the health of a cluster? Also where can I view all the nodes in a cluster?

Thanks

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

Hi Radoslav,

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.

Thanks

I would still direct you to RHQ for the sake of monitoring and alerting: RHQ - JBoss Community

Something is telling me that "execution" and monitoring should ideally be 2 separate systems.
