Monitoring backup exec server performance

[ramy_shaker]

Dears ,

i get the AVG  Page fault/sec = 1500     , is it acceptable or high value ?

That metric is unimportant.

Monitor the following instead

network bandwidth (including FC HBA's too)

CPU

RAM utilization.

disk queue length

For the first 3, use the 70% rule.  Never let those get over 70% for sustained periods during heavy activiy.  

Disk queue length depends on the drive counts, but it shouldn't go over 2.  But this is based on the average, which is over divided by the disk count.  

So if RAID, you have to do queue length / spindle count = hopefully <2

Hello,

Windows performance counter “Page fault/sec” includes both soft and hard page faults. Soft page faults are not much of a concern as the pages are already available in RAM, just that they are not part of the processes accessing those pages. It is the hard page fault that impacts performance because in this case data is read from the page file on the hard-disk. Hard-disk seeks and reads are slow. It will be useful to know the below things to answer the original question.

*Avarage “Page Reads/sec”, Avg “Pages Input/sec” and  avg “Page fault/sec”. Ideally they should be averaged over the time when BE jobs are run.

* Physical memory size of the server.

Thanks.
