Tracking changes in the number instances created and service requests

You can use the Instrumentation page in the Process Monitor to log and track the number of instances that are created and the number of service requests. You can then investigate changes in the data to determine whether there is a problem. For example, if there is a spike in the number of new instances that are created, you can use the data to understand whether the spike is a result of a normal business situation, an application error or a denial of service attack.

To view the number of process instances that were created for each BPD since the server started:
  1. Log in to the Process Admin console, by entering the url. For example: http://servername:9080/ProcessAdmin, where servername is the name of your server and 9080 is the default port.
  2. In the Server Admin area of the Process Admin console, expand Monitoring to list the available monitoring options.
  3. Click Instrumentation. You can see how many process instances were created for each BPD since the server started. You can also see how many service requests were made to each process app, for services such as integration service, human service, Ajax service.
  4. Click Save to save the instrumentation data as an XML file.
You can also perform these tasks by using the Process Monitor:
  • Retrieve instrumentation data as XML by using the InstrumentationManager MBean
  • See the rate of change by monitoring the BPDInstancesStarted MBean
