Subject [jira] [Updated] (HBASE-17578) Thrift per-method metrics should still update in the case of exceptions
Date Mon, 06 Feb 2017 20:51:41 GMT

     [ https://issues.apache.org/jira/browse/HBASE-17578?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Helmling updated HBASE-17578:
----------------------------------
    Release Note: In prior versions, the HBase Thrift handlers failed to increment per-method
metrics when an exception was encountered.  These metrics will now always be incremented,
whether an exception is encountered or not.  This change also adds exception-type metrics,
similar to those exposed in regionservers, for individual exceptions which are received by
the Thrift handlers.

> Currently, the InvocationHandler used to update per-method metrics in the Thrift server
fails to update metrics if an exception occurs.  This causes us to miss outliers.  We should
include exceptional cases in per-method latencies, and also look at adding specific exception
rate metrics.
