Description
Shows the CPU usage. If this value is continuously high, the
CPU processing power is likely to be a bottleneck.
Indicates the number of pages per second that are read from
or written to the disk to resolve page faults. If this value is
high, it is likely that the amount of memory is insufficient.
The closer this value is to 0, the better.
Indicates the size of the physical memory available for
processes. If this value indicates a decreasing trend, it is
likely that there is a memory leak.
Indicates the size of the memory area that will never be
paged out to the disk and that 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.
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.
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.
Shows the network bandwidth.
