url for integration monitoring service detail page

I’m trying to dynamically build the url that will take me directly to the Service Detail page in My webMethods/Integration Monitoring for the audit record of a service. The url is something like:

http://xxxxxxxx:8088/webm.apps.mon.integration.service.detail?
wmp3956.pca_m=void&wmp3956.getDetails_getDetails_contextId=3dd5d5809f4711db9b1f9a168692a478

Any idea what the wmp3956, specifically the number 3956, represents and where I can get it from? It seems to change from installation to installation.
