How to find #of a given user connections in RTC or list of users logged into RTC

Our team is implementing programmatically opening defects in RTC after a test run.  A JUNIT testsuite is executed locally on 5 different servers @ sametime and in the end it connects to RTC server to open a defect from each server. RTC credentials used are same on all servers. We've a way to identify each issue uniquely in our report and to create single defect for it.  But due to timing issue, we've seen few instances where duplicate defects are opened few seconds apart from these servers.  I was wondering if there is a way to programmatically figure out how many active session a given user has.
Appreciate any help!
Thanks!
