[jira] [Commented] (MESOS-5269) Replace Master/Slave Terminology Phase I - Update Metrics

["Jay Guo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-5269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15255944#comment-15255944 ] 

Jay Guo commented on MESOS-5269:
--------------------------------

If we take similar approach as multi-named flags, we could also have multi-named metrics, which take vector of strings during construction and treat them as aliases for the same metric.

e.g.
{code}
Gauge(const std::vector<std::string>& names, const Deferred<Future<double>()>& f)
  : Metric(name, None()), data(new Data(f)) {}
{code}
