-----------------------------------------
Summary: expose global ColumnFamily metrics
Key: CASSANDRA-7273
URL: https://issues.apache.org/jira/browse/CASSANDRA-7273
Project: Cassandra
Issue Type: New Feature
Reporter: Richard Wagner
Priority: Minor
It would be very useful to have cassandra expose ColumnFamily metrics that span
all column families. A general purpose cassandra monitoring system built up
around the current ColumnFamily metrics really only has a couple of choices
right now: publish metrics for all column families or fetch metrics for all
column families, aggregate them and then publish the aggregated metrics. The
first can be quite expensive for the downstream monitoring system and the
second is a piece of work that it seems is better pushed into cassandra itself.
Perhaps these global ColumnFamily metrics could be published under a name of:
org.apache.cassandra.metrics:type=(ColumnFamily|IndexColumnFamily),name=(Metric
name)
(Same as existing ColumnFamily metrics, but with no keyspace or scope.)
