---------------------------------------
Summary: GraphiteSink can specify which tags to export into the
metrics prefix
Key: HADOOP-14307
URL: https://issues.apache.org/jira/browse/HADOOP-14307
Project: Hadoop Common
Issue Type: Improvement
Components: metrics
Affects Versions: 2.7.3, 2.7.2, 2.7.1, 2.7.0
Reporter: Damien Claveau
Assignee: Damien Claveau
Priority: Minor
Fix For: 2.7.3, 2.7.2, 2.7.1, 2.7.0
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
