2012-10-22 Thread Nicholas Satterly
Just to make it clear, you define statically your descriptors in the metric_init function, and regularly, you check for new metrics and call gmetric accordingly ? No, using gmetric within a python module means you do not need to use metric_init() to initialise any metrics at all. However, we

Hi, there is a way to query gmond headnode for any data, I use it, it works well. My question is: is there a way to query local gmond instance for local data, without it being a headnone? Further explanation of context: *Currently* data is being collected by gmetad, which is connecting to
