Performance counters
There are several performance counters you can monitor using the standard
Windows Performance Monitor. This comes with every version of Windows. To
open the Windows Performance tool:
1. Click Start .
Go to Administrative Tools .
Next click on Performance .
For information on how to create and monitor objects go t o:
com/fwlink/?LinkId=478 81 . The objects you will want to monitor on your DPM
server(s) are as follows.
Processor usage
If your processor usage stays above 95% for long periods of time this means your
processor is overworked and there is some issue.
Some potential issues could be that DPM jobs are synchronizing at the same time and
they are processor intensive. Make sure you DPM processor is equipped to handle
the workloads. Compression on the wire for DPM has been enabled on protection
members. This improves network performance but can increase processor usage.
Disk queue length
If you have more than 80 requests for long periods of time this is typically over
six minutes. A potential cause is again that multiple DPM jobs running can cause
high disk usage. Be sure the disks you are using in DPM can handle the current
Memory usage
If your available memory is low—less than 50 MB—this is a big problem. Potential
issues could be that other applications on the DPM server are using large amounts
of memory, or multiple DPM jobs are running that use large amounts of memory.
Make sure you meet the 4 GB minimum DPM memory requirements. Remember it is
recommended that you have at least 8 GB of RAM for your DPM server. The full list
of hardware requirements can be found here: 80.aspx
