> Key: HADOOP-14307
> URL: https://issues.apache.org/jira/browse/HADOOP-14307
> Project: Hadoop Common
> Issue Type: Improvement
> Components: metrics
> Affects Versions: 2.7.0, 2.7.1, 2.7.2, 2.7.3
> Reporter: Damien Claveau
> Assignee: Damien Claveau
> Priority: Minor
> Fix For: 2.7.0, 2.7.1, 2.7.2, 2.7.3
>
>
> This Jira is a feature proposal to add the ability in GraphiteSink to specify
> which Tag (Name/Value) pairs are to be flattened in the metric prefix.
> The motivation for this is that currently, all the tags are included in the
> prefix like this :
> graphite_prefix.Context=$context.Process=$process.Tag1=$value1.Tag2=$value2..Tag9=$value9.metric
> This requires a bunch of rewriting rules (and complex regexp) in the metric
> aggregation servers (carbon-relay, carbon-aggregator, ...) .
> The feature would be exactly the same as the solution implemented in the
> GangliaSink : https://issues.apache.org/jira/browse/HADOOP-7507
> See also the commit :
