|
Memory: Available Bytes
|
<4MB = memory leak
the amount of physical memory, in bytes, available on the computer. If <4MB, check for memory leaks and add RAM is necessary |
|
|
Memory: Pages/sec
|
>20 = paging setting issue
rate at which pages are read from or written to disk. If >20 look at paging settings |
|
|
Paging File: % Usage
|
>70 = not healthy
the amount of the Page File instance in use in %. |
|
|
Physical Disk: Avg. Disk Queue Lenght
|
(N + 2) = # of disks + 2 is OK
A bottleneck condition exists if you've got 1 disk (spindle) and the queue length is > 3. the average numer of both read and write requests that were queued for the selected disk during the sample. # of spindles + 2 is acceptable. |
|
|
Logical Disk: Free Megabytes
|
<15% = unhealthy
the unallocated space, in megabytes, on the disk drive. |
|
|
PhysicalDisk: %Disk Time
LogicalDisk: %Disk Time |
>90% = unhealthy
the % of time that the disk was read/write requests. Could be hardware issue or the data on the disk is too large. |
|
|
Processor: % Processor Time
|
>80% = unhealthy
% of time the processor spends to execute a non-idle thread. Could be a process-intensive process (move to another processor) or add another processor. |
|
|
Processor: Interrupts/sec
|
the average rate, in incidents/sec, that the processor received and serviced hardware interrupts. If the value increases w/out add't processes, could be hardware related.
|
|
|
Server: Bytes Total/sec
|
If = to NIC bandwidth then increase bandwidth of network.
|
|
|
Server: Pool Paged Peak
|
Should be =< RAM value
Add more RAM if > than RAM. |
