To evaluate the load on Citrix XenApp Server we can run the command “qfarm /load”, it will display different values. This post will enhance your understanding of the hidden meaning of all those values.

• 0 to 9998: This is the normal range for Load Manager i.e. load on the server is normal and it can handle more load.

• 99999: No load evaluator is configured.

• 10000: Load is at 100 percent (full load) and it is not in a position to handle additional load.

• 20000: The XenApp Server contains an incorrect server edition or a license mismatch. To fix the issue match the version of XenApp installed with the licenses deployed.

XenApp 6/6.5 server is unable to contact the license server after a reboot. The output of the Qfarm /load command indicates a server load of 20000

• 99990: Results when a custom administrator with restricted rights runs the following QFARM commands:QFARM SERVER /APP

QFARM /APP

QFARM /APP <appname>

QFARM /ZONEAPP
