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

</div>
<div>Another option is to use the PerfMgr which is part

<div>There is an example of that below too, using the

Hello all<br>
<br>
I want to monitoring ports in IB fabric.<br>
<br>
I happened to notice in the out of perfquery some
counter like a ticks<br>
and port sampling. Its will be great for accurate
monitoring. But I cant<br>
found some info about setup and using sampling controi
for IB ports.<br>
<br>
How to configure and use sampling contol for IB ports?
Can anybody give<br>
me documentations/links or examples? I cant found it In
Google.<br>
Are there any restrictions on the amount of data
collected in this<br>
sampling mode?<br>
<br>
If its offtop then redirect me please<br>
<br>
Thanks for you time<br>
<br>

Hi Susan Coulter<br>
<br>
Very thanks for your reply<br>
<br>
Very interesting and especially for perfmon. How I understand the
perfmon can dump all counters very fast (i hope it more fast then
dump it in cycle one by one). Thanks for this info.<br>
<br>
But nevertheless, can your or somebody explain how to use sampling
control mechanism for perfquery ?<br>
