Resource Monitor- Disk

-

i have combed internet looking answer this, have been unsuccessful far.  

users complaining slow performance on server , network has checked out ok.  i'm looking @ disk perf , here image in resource monitor when complaints slowness worst.  note green , blue line.  what blue line in disk image tell me?  is there more activity array can handle?  any detail on image means helpful haven't found in depth explanation anywhere.  i've captured many disk counters in perfmon, below.



hi,

monitor disk performance issue, can select following counters:

server\bytes transmitted/sec
server work queues\queue length
physicaldisk\disk bytes/sec 
physicaldisk\avg. disk queue length

1st counter tells server busy or not in sending data out.

2nd counter tell if system waiting send tasks disk.

3rd , 4th counters tell whether disk  busy cater requests. larger 4th counters is, busier means (more tasks waiting).

from second picture, both disk read bytes/sec , current disk queue length high in time of course cause disk performance issue. 


please remember mark replies answers if , un-mark them if provide no help. if have feedback technet support, contact tnmff@microsoft.com.
