[GE users] Infiniband loadsensor

Hello Reuti!

I would believe that the boolean variable would be referenced as a "true/false" thingy. I can understand the mapping 1/0, but would it be the same thing as for:

qconf -sq all.q
...
load_thresholds       np_load_avg=1.75,[@infiniband0=ibstate=false]

It seems to accept both versions.

Sorry, should read: NONE,[@infiniband=yourcomplex=0]
