[jira] [Commented] (HADOOP-10727) GraphiteSink metric names should not contain "."

    [ https://issues.apache.org/jira/browse/HADOOP-10727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14038178#comment-14038178 ] 

Charles Wimmer commented on HADOOP-10727:
-----------------------------------------

Other systems that emit metrics to graphite use a similar process.  For example, collectd.  https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_write_graphite

We should consider making the escape character configurable.

> Sometimes the names of the metrics sent to Graphite contain "." in them (such as hostnames). Graphite interpret these dots as a separator for directories causing long directory hierarchies. It would be easier to replace them to "_" in order to have easier to read metric names.
