This Knowledge Script monitors the overall hit ratio for all protocol objects per session. The hit ratio is the percentage of time protocol objects that are reused or available in the client cache.
A higher hit ratio indicates reduced data transmission and better performance. A low hit ratio is caused when a session is updated with new information that is not re-used, or is not used within the number of bytes available for the client cache.
If the hit ratio for any session is lower than the threshold you set, an event is raised.
NOTE:This Knowledge Script is not supported on Windows Server 2012 and Windows Server 2012 R2 because the Total Protocol Hit Ratio counter is not available for Terminal Services Session.

Description |
How to Set It |
|---|---|
|
Raise event if the protocol hit ratio is below threshold? |
Set to y to raise an event if the protocol hit ratio is below threshold. The default is y. |
|
Collect data for protocol hit ratio? |
Set to y to collect data for charts and reports. If set to y, the script returns the overall hit ratio for all protocol objects per session. The default is n. |
|
Threshold -- minimum protocol hit ratio |
Specify the minimum protocol hit ratio percentage per session to be reached before an event is raised. The default is 50. |
|
Event severity if the protocol hit ratio is below threshold |
Set the event severity level, from 1 to 40, to indicate the importance of the event in which the protocol hit ratio is below threshold. The default severity level is 5. |
