      Description

      Metrics used to be accessible in JMX and published in Graphite.

      Since the directories and the new cache metrics has been added there is way too much metrics (~800 on a default instance) to report all of them through Graphite, instead of filtering at the Graphite level, it is better to not collect them and not send them in the metric GraphiteReporter.

      Having so much metrics impacts application perfs (time to collect them every metrics.graphite.period) and overload the graphite server disk IO especially in the case of a Nuxeo cluster.

      A filter should be added to limit the number of metrics published.
