Subject [jira] Updated: (CHUKWA-557) Make differentiation between recordName and contextName and clean up chukwa metrics
Date Sun, 14 Nov 2010 07:06:13 GMT

     [ https://issues.apache.org/jira/browse/CHUKWA-557?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Yang updated CHUKWA-557:
-----------------------------

    Description: 
Metrics emited by Chukwa Agent through MetricsContext is structured as:

contextName: chukwaHttpSender
recordName: chukwaHttpSender

The same context is repeated twice in the naming hierarchy.

Ideally, the structure should be:

contextName: chukwaAgent
recordName: httpSender

Therefore, the metrics can be collected in chukwa table, column family: agent_httpSender.
 In sequence file, it will be chukwa data type directory, and hashmap looks like:

{noformat}
{ "contextName":"chukwaAgent","recordName":"httpSender",...}
{noformat}

  was:

metrics  (was: Make differentiation between recordName and contextName)

Chukwa Metrics also needs a cleaner parser.
