Re: [Ganglia-general] gmond python module, dynamic number of descriptors
Hi Jean-Baptiste,
We had a similar requirement for dynamically adding new metrics. The only
way we could make this work is to call gmetric from within the python
module. A bit of a hack, I know, but it also gives you the ability to set
the "dmax" option which means old metrics will expire and be forgotten by
the gmond which is just as important as dynamically discovering new metrics.
By the way, the python module is used to collect some metrics that are not
dynamic. For example, we have a metric that reports the number of dynamic
metrics we are collecting which we have found very useful when trouble
shooting problems with the python module itself.
Regards,
Nick

Re: [Ganglia-general] Additional Bars
Please see below. I thought by installing libffi and libgcc, it would install the needed libraries, but it did not. What else am I missing? Thanks.
