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.

Have you taken a look at our GSoC Ideas Page?  That's the first place I
would start:

Re: [Ganglia-general] Gauges verses counters

[Silver, Jonathan]

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? What will show 
>> on the graphs?
>> How does ganglia know that it's a gauge and not a counter?

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?

After 24 hours, rrdcached seems to have solved it.

Thanks for you advice, and also to Mozammil for his.
