Concurrent users

Purpose

On a BusinessObjects system, the number of concurrent user sessions can be used as an indicator when performance problems are experienced. <br/> The same user can be logged multiple times or never logged out, consumming unnecessary ressources. <br/> This monitor will check the number of concurrent sessions and can generate alerts if the overall number is too high, or if one user has too many sessions.

Configuration hints

Use the button “Load users” to get the list of the users defined in your system.<br/> Then use the filters to set rules based on a specific user or the overall number.
