[Users] how to use sample control for port counters

[Coulter, Susan K]

The perfquery command will tell you about the throughput and errors on a port.
The smpquery command will tell you more of what you might want to know about a port.
They come from the infiniband-diags module / RPM.
Examples are below.

Another option is to use the PerfMgr which is part of the OpenSM code base, if you are running osm on a host.
There is an example of that below too, using the default port/localhost.

Hello all

I want to monitoring ports in IB fabric.

I happened to notice in the out of perfquery some counter like a ticks
and port sampling. Its will be great for accurate monitoring. But I cant
found some info about setup and using sampling controi for IB ports.

How to configure and use sampling contol for IB ports? Can anybody give
me documentations/links or examples? I cant found it In Google.
Are there any restrictions on the amount of data collected in this
sampling mode?

If its offtop then redirect me please

Thanks for you time
