Determine if RPT schedule is runing using command line?

Question

Anyone know if its possible to query a Rational Performance Tester 'Controller' from command line and determine if a schedule is executing?
I'm aware that you can query Agents using commands below, but if a RPT schedule fails for some reason the agent process usually continues to be active. Meaning, although a result is returned on Agent, the Controller may not be driving the workload.

[root@agent ~]# ps aux | grep [s]cheduleName
root     30000  4.2 11.4 2712004 949872 ?      Sl   13:17  13:46 java
-Drptserver.rootDiscoveryUrl=http://controller.com:7080/deployment/
-Drptagent.agentName=agent.com -Drptagent.engineName=agent.com
-Drptagent.scheduleName=scheduleName 
-Drptagent.rptDeployDir=file:/tmp/rpt/deployment_root/root/A1E0E83B67946D90D6F6E53236393936/

This has proven to be most effective:

ps aux | grep [s]cheduleName
