Environment	Product: OpenEdge Version: 11.5 and later OS: Windows Other: Progress AppServer for OpenEdge / PASOE

Question/Problem Description

On Windows, PASOE multi-session agent doesn't work with progetstack utility.

The proGetStack request to generate a protrace for a multi-session agent (MSA) fails with error:

Cannot get stack of process <pid>.
The process id you specified may be invalid, not an OpenEdge ABL process or is a process from a pre 10.1C release of OpenEdge.

Steps to Reproduce	- Start a PASOE instance - Look up the PID for the "OpenEdge AppServer (Multi-thread)" in Task manager (there should be one for the default ABL application in the PAS instance) - Open proenv prompt, run "progetstack <pid>" where <pid> is the PID found above

Clarifying Information

Error Message	Cannot get stack of process <pid>. The process id you specified may be invalid, not an OpenEdge ABL process or is a process from a pre 10.1C release of OpenEdge.

Enhancement Number

Cause

This is a known limitation, progetstack does not support the multi-session agent.

Resolution

Get a stack trace of a specific session, with is much more useful then a stack of all the msagent's threads.
Available through JMX, OE Manager (oemanager.war), or the REST API to call stack information without OEE/OEM:

http:/hostname:port/oemanager/applications/<ABL application name>/agents/<agent PID>/sessions/<session id>/stacks
