after thinking a bit about this issue, I realized that reducing the DMAX
value would be OK in some scenarios, but actually it is not what I
needed right now. Instead, I wanted to try and change the definition of
the metric to inject to Ganglia.

I was doing:

[
  Aggregate = "SUM";
  Name   = "CPUsInUse";
  Value  = Cpus;
  Desc   = "Number of CPUs in use";
  Requirements = State=="Claimed" && Activity!="Idle";
  TargetType = "Machine";
]

while I would need:

[
  Aggregate = "SUM";
  Name   = "CPUsInUse";
  Value  = 'State=="Claimed" && Activity!="Idle"?1:0';
  Desc   = "Number of CPUs in use";
  TargetType = "Machine";
]


The difference being that the first one will simply not inject any
metric to Ganglia when no CPUs are used by HTCondor, while the second
one will (at least in my head :-)) inject 0 in the same scenario.

But the problem is that no matter how I try to write the Value
expression, it doesn't seem to work and no metric value is injected to
Ganglia.

Any idea on how to debug this or what the Value expression should really
be?

Thanks,
