Thanks for your feedback, the results of the master..sysperfinfo is NULL (0 rows) using the monitoring user account (sysadmin) for that particular server only while 4 other servers, it`s retrieving the results as it should be. So I guess it`s a permission issue but I cannot resolve it myself as I am not fully aware of the software requirements, so plz need ur assistance through web session to close this tkt.
Thanx
