XenApp Terminal Server Perfmon Baseline Performance Monitoring

When performing performance analysis or testing of a XenApp server the following collection of perfmon counters should enable a good assesment of the servers performance. This information was provided by a Microsoft technician on a site visit.

Memory

• Pages/Sec
• Available Mbytes
• Committed Bytes
• Page Faults/Sec

Network Interface

• Bytes Total/Sec
• Packets/Sec

Paging File

• % Usage

Physical Disk

• % Disk Time
• Avg Disk Bytes/Transfer
• Avg Disk Queue Length
• Avg Disk Sec/Transfer
• Disk Transfers/Sec

Processor

• % Processor Time
• % Privilege Time
• % User Time
• Interrupts/Sec

System

• Context Switches/Sec
• Processes
• Processor Queue Length

Print queue

• Bytes Printed/sec
• Jobs

Process

• Handle count
• IO Data Operations
• Private Bytes
• Thread Count
• Working Set
• %idle Time
• %Priviliged Time
• %Proccesor time
• %User Time

The following counters are for Terminal Servers specifically, and will aid in translating the output into meaningful information:

Terminal Services

• Active Sessions
• Total Sessions

Terminal Services Session

• % Processor Time
• Page Faults/Sec

I got the information from a good article on using perfmon to monitor a servers performance, the article includes information on how to interpret the result collected as well.
