Summary

Argent Advanced Technology has been introduced a new Rule category ‘Listening Session Count Rules’ in Argent for XenApp under ‘XenApp Session Monitoring Rules’ to check whether the count of listening sessions in XenApp 6.5 servers matches the threshold condition

Example:

‘Listening Session Count Rules’ check the listening session count in XenApp Server

Rule ‘RULE_LISTEN_SESS_CNT_AT_LIMIT’ is broken, if the listening sessions count in XenApp Server is greater than 50

Technical Background

Listening sessions are special-purpose sessions closely related to idle sessions

Their purpose is to listen for session requests on their assigned protocol

They handle initial session setup and assign the incoming session request to the next available idle session

This Rule compares the count of sessions in listening state in XenApp Server with the given threshold value

Any unusual increase in count requires immediate action as this severely affects the stability of XenApp Server

The Rule monitors all listening sessions running in the XenApp 6.5 server
