Brandon Williams commented on CASSANDRA-7273:
---------------------------------------------
I think the only sane way to do this is to knock out CASSANDRA-6539 first, then
have this portion sum those stats.
> expose global ColumnFamily metrics

> 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.)
