Counter Description
1 Processor %Processor Time Shows the CPU usage. If this value is
continuously high, the CPU processing power is
likely to be a bottleneck.
2 Memory Pages/sec Indicates the number of pages per second that are
read from or write to the disk in order to resolve
page faults. If this value is high, it is likely that
the amount of memory is not sufficient. The
closer this value is to 0, the better.
3 Available Bytes Indicates the size of physical memory available
for processes. If this value indicates a decreasing
trend, it is likely that there is a memory leak.
4 Pool Nonpaged Bytes Indicates the size of the memory area that will
never be paged out to the disk and stays in the
physical memory as long as it is allocated. If this
value indicates an increasing trend, it is likely that
there is a memory leak.
5 PhysicalDisk %Disk Time Indicates the percentage of time that the disk is
busy reading and writing. If this value is
continuously high, the disk performance is likely
to be a bottleneck.
6 Network Interface Bytes Total/sec Indicates the number of bytes per second that are
sent and received by the network adapter. If this
value is continuously high compared to the value
of No.7, the network is likely to be a bottleneck.
7 CurrentBandwidth Shows the network bandwidth.
