You can find diagnostic information in /proc/qnetstats. If this file doesn't exist, Qnet isn't running.
The qnetstats file contains a lot of diagnostic information that's meaningful to a Qnet developer, but not to you. However, you can use grep to extract certain fields:
# cat /proc/qnetstats | grep "compiled" **** Qnet compiled on Jun 3 2008 at 14:08:23 running on EAdd3528
or:
# cat /proc/qnetstats | grep -e "ok" -e "bad" txd ok 930 txd bad 0 rxd ok 2027 rxd bad dr 0 rxd bad L4 0
If you need help getting Qnet running, our Technical Support department might ask you for this information.
