<div>There are no such IBA standardized counters. Some vendors
support flow related counters which are beyond the IBA spec.
Contact your vendor for more info.</div>

<br>
I want to deep monitoring utiization channels of IB fabrics.<br>
<br>
In some topologies the same path segment between 2 switches
can be used by different hosts.<br>
<br>
Therefore, you need to determine exactly with whom each host
exchanges.<br>
<br>
If we have source-receiver you can get the route path.<br>
<br>
Knowing the route path the source-receiver and the time of
the exchange, you can understand who and how much this
channel is using.<br>
<br>
Is it possible to find out who the host is exchanging at the
moment:<br>
- from /proc of hosts or something like that from the
qp.dest of application on this host or something else ?<br>
- from openSM (in each exchange hosts will be get request to
SM for PathRecord. Can any statistics be maintained in SM ?)<br>
- or can you find out how else?<br>
<br>
Sorry for possible offtopic and my english<br>
<br>
Thanks for you time<br>
