• Total CIFS Server Bytes/sec
The total Bytes of data the cluster is sending and receiving from the network.
This counter relates strictly to the Server service and is a measure of how busy
the cluster is.
• Total CIFS Server Sessions
The total number of active sessions on each server in the cluster.
• Total CIFS Server Files Open
The total number of files currently open on each server in the cluster.
Node Counters
The node counters provided for the Microsoft Windows perfmon utility
are as follows:
•% Processor Time
The percent of processor utilization for the server. This counter measures the
percentage of time the processor is accomplishing meaningful work (i.e., non-
idle threads). Valid values range from 0 to 100 (%). A sustained value of over
75 percent for a long period (i.e., days and weeks) indicates that the processor
is a bottleneck and should be upgraded.
• % Processor Queue Length
The average number of threads waiting for processor time in the server. A
sustained value of more than two times the number of processors in the
system generally indicates a CPU bottleneck. Faster processors may be
needed.
• % Committed Bytes in Use
The percent of currently committed memory (Bytes) of the Commit Limit for
the server. The committed memory is the physical memory currently in use,
where the same amount is reserved in the paging file should it need to be
paged out. The Commit Limit is an upper limit of the virtual memory (i.e.,
total RAM + paging file) that can be allocated on a system.
• % Paging File Usage
The percent usage of the paging file in the server. If the counter approaches 90
percent, consider resizing the paging file to accommodate system needs.
