Charts on the Activity Summary page
Shows the total CPU utilization across all processors in the machine, categorized into User Time and Privileged Time.
Note: The User Time and Privileged Time series are each represented by a single line, and by an item in the legend at the right of the chart.
Shows the rate at which pages are being swapped in and out of memory.
A sustained high rate of paging can cause problems with overall system degradation due to disk thrashing and CPU load.
Note: Each Paging Rate series is represented by a single line, and by an item in the legend at the right of the chart.
Shows the incoming and outgoing packet rates as an aggregate across all network cards in the system.
Note: The Packets Sent and Packets Received series are each represented by a single line, and by an item in the legend at the right of the chart.
|Processor Queue Length||
Shows the total number of threads (program execution units) that are waiting to be run on ALL processors. A sustained processor queue length greater than three times the number of processors can indicate processor congestion.
Note: To view Server Work Queues for the individual CPUs in the system, see the CPUs Page in the CPU drilldown.
|Disk Queue Length||
Shows the number of I/O requests that were queued for each logical disk.
Disk Queue Length indicates how heavily loaded a disk subsystem is. High queue lengths mean the disks are struggling to process the I/O load being put on them.
Note: Each logical disk on the system is represented by a single line on the chart, and by an item in the legend at the right of the chart.
Shows how much physical memory (RAM) and Virtual Memory Windows is using.
Physical Memory usage will normally remain close to the total amount of physical memory installed on the system unless the amount of physical memory you have exceeds the amount of virtual memory that Windows is using.
Windows normally keeps some physical memory available (free) for immediate reuse.
Virtual Memory usage increases and decreases as Windows processes requests and gives up memory and as processes are started and stopped.
A steady increase in Virtual memory usage can indicate that a process on the system has a memory leak.
Note: The Virtual Used and Physical Used series are each represented by a single line, and by an item in the legend at the right of the chart.
