Is there a way to make ganglia hyperthread - aware in v3.0?
We have a cluster of dual Xeons with hyperthreading, which ganglia
reports as 4 processes. This is annoying when using the web frontend,
since full load appears to only be 1/2 load, and people think there are
twice as many CPUs available.
I'm a little confused as to why you want this. If you have dual
processors with HT enabled, then a full load is four processes running,
which would give you a load average of 4.0. And since ganglia will
indicate that a load of 4.0 is 'full load', then it currently does the
right thing.
So I guess my question is, how is 4 processes running on a dual proc
machine with HT not full load? And if you want full load to be 2
processes running, why are you using HT?
