Chapter 15: Performance Monitoring 197 • Avg % Paging File Usage The average percent usage of the paging file in the cluster. If the counter approaches 90 percent, consider resizing the paging file to accommodate system needs. • 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., nonidle 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.
