[Ganglia-general] Gauges verses counters
We are planning on using jmxtrans to collect and propagate a number of metrics to ganglia. There is no place in jmxtrans to define the metric as a counter or a gauge. If we do NOT predefine the metric in rrds, what will happen? What will show on the graphs? How does ganglia know that it's a gauge and not a counter?

Re: [Ganglia-general] Gauges verses counters
FYI, Ganglia already understands the output from this alternative JMX monitoring solution: https://code.google.com/p/jmx-sflow-agent/ I think it has similar properties to embedded-jmxtrans. Much better to have the JVM push the stats every 20 seconds or so than have to poll for them remotely over an encrypted connection. And using the java-agent hook means you only have to change the JVM command-line.

Re: [Ganglia-general] Gauges verses counters
Thanks for the reply, but the question was really a generic one. We are adding our own metrics and collecting them via jmxtrans (and yes ganglia has special built-in support for sflow, but not For our application specific counts). >> There is no place in jmxtrans to define the metric as a counter or a gauge. >> >> If we do NOT predefine the metric in rrds, what will happen?
