Monitoring the Petals SE ASE

In this version of the Petals ASE, the monitoring is based mainly on the ActiveMQ monitoring.

The following indicators are interesting:

• number of requests processed with fault in the persistence area: a fast increase of this value should show:
  • the target service provider or its backend are overloaded or down,
  • a DoD of the ASE service provider client
• number of retried requests: an increase of this value should show:
  • the target service provider or its backend are overloaded or down,
  • the ASE service provider client doesn't respect the SLA

Monitoring with basic tools

JVisualVM

As ActiveMQ is provided with a JMX API, it is very easy to connect the JVisualVM to the ActiveMQ's JVM. See http://activemq.apache.org/jmx.html.

Don't forget to install into JVisualVM its plugin VisualVM-MBeans previously.
