Title: Cognos Server Load Balancing!!
Post by: mycognos on 11 Nov 2009 09:57:59 AM
Hi,

I have Implemented Load balancing among 2 application servers(say a and b). I have one Webserver(say c) also in which gateway component is installed. For load balancing I have added the one more dispatcher to the 'Dispatcher URI for gateway' of the server a ie the primary server. In this case is there any way to check which request is going to which server?

Thanks in advance...mycognos

Load balancing is dong among the dispatchers, not triggered via the gateway. (those 2 entries are just for redundancy)
If your dispatcher setup is default, the third report request should go to the first bibus on the second dispatcher.

Asuming windows, open taskmanager on server and monitor bitkservermain.exe to take cpu cycles to see it's working.
Otherwise use Cognos auditing to log dispatcher activity (not verified myself).

The servers are Linux machines....
Currenlty I am checking the Report Services, where I can check the total number of requests processed by each server.....

Capacity in the admin section of Cognos connection, and real usage only in audit logging (with also admin page in real-time usage).
