[Mauiusers] Moab and Ganglia integration

[Chris Samuel]

Hi folks,

I've turned on Ganglia in our Moab installation and it seems to work quite 
nicely, it gives us real stats for disk usage finally, as well as spotting 
that three nodes which had recently had motherboards swapped out had not had 
HyperThreading turned off and consequently were reporting 4 cpus's versus 
PBS's config of 2!

Two questions though:

1) Is it possible to confine Moab to only take notice of those nodes that are 
found through both the PBS and Ganglia RM's ?

Our Ganglia information includes head, storage and management nodes which we'd 
prefer Moab to ignore.


2) Moab is complaining about not being able to get the workload's through 
Ganglia, diagnose -R says:

RM[ganglia]  type: 'NATIVE'  state: 'Active'
  Cluster Query URL: 'ganglia://'
  Flags: 'typeIsExplicit'
  P[0]: Host: ''  Port: 8649
  Event Management:  (event interface disabled)
  RM Performance:  Avg Time: 0.92s  Max Time:  3.13s  (502 samples)

RM[ganglia] Failures:
  Thu Oct 21 16:30:27  workloadquery    'cannot get workload info' (251 of 251 
failed)  (etc etc)

Is this something that is expected to be injected into Ganglia through 
Gmetric, or are we too far behind with our version of Ganglia (2.5.4) ?

cheers!
Chris
