Chris Burroughs commented on CASSANDRA-4430:
--------------------------------------------
New draft up !
https://github.com/cburroughs/cassandra/tree/metrics-config-2, uses
metrics-report-config SNAPSHOT with "qualified" names
(org.apache.cassandra.metrics.ClientRequest...)
* Rebased against latest 1.2 branch. I'm running 1.2 and hope to have this on
my production clusters soon.
* Added a sample file that sends all global (not good terminology, as in
metrics that are not per connection/columFamily) to a file
* Didn't like hard coding in bin/cassandra so
-Dcassandra.metricsReporterConfigFile must be specified for this to do anything
CSVReporter only works if the non-qualifed names are unique. The same uses the
console reporter to dump everything to one big file which is really only useful
as a sample
> optional pluggable o.a.c.metrics reporters

> CASSANDRA-4009 expanded the use of the metrics library which has a set of
> reporter modules http://metrics.codahale.com/manual/core/#reporters You can
> report to flat files, ganglia, spit everything over http, etc. The next step
> is a mechanism for using those reporters with o.a.c.metrics. To avoid
> bundling everything I suggest following the mx4j approach of "enable only if
> on classpath coupled with a reporter configuration file.
