monitor bandwidth used

Hi ,

You can have a look at this
http://support.microsoft.com/kb/324752/en-us .

you can monitor specific problems with refrence to the disk i/o if you go the performance logs and alerts .

Sorry if you already know this and you were looking for something else on this topic .

Cheers ,
VKR

Yes, I was looking for something else. I would've thought that EMC would definetely have something to be able to monitor the bandwidth. I mean, how does everybody else do it?

We have a fibrechannel switch and it should be capable of doing 2 Gb between the HBA host and the SAN. When they build this stuff, they must have some way to test the bandwidth.

Anybody else know of any monitoring software??

Some switches (eg. Brocade's) support the SNMP protocol. I don't know which ones you're using but there are some documentations on the web showing how to use Multi Router Traffic Grapher (MRTG) to monitor bandwidth on per-port basis on fibre channel switches.

GilbertF,
Are you concerned about the performance of the switch or of the array? I have yet to see a fabric become a bottleneck, but have definitely seen the array become a bottleneck when monitoring application performance.

The reason I ask this is that monitoring the amount of a 2Gb path used by a server in a SAN fabric will not give you an accurate view of the performance of your SAN. Some of the best methods for measuring the performance of your SAN in relation to a particular server is the monitor the LUNs assigned to the server using Navisphere Analyzyer. The read and write i/o, and the write MB/s will give you a good indication if the SAN is a performance bottleneck.
