Doug Cutting commented on HADOOP-132: ------------------------------------- A nit: the code should be in package org.apache.hadoop.metrics, not org.hadoop.metrics. > An API for reporting performance metrics > ---------------------------------------- > > Key: HADOOP-132 > URL: http://issues.apache.org/jira/browse/HADOOP-132 > Project: Hadoop > Type: New Feature > Reporter: David Bowen > Attachments: javadoc.tgz > > I'd like to propose adding an API for reporting performance metrics. I will > post some javadoc as soon as I figure out how to do so. The idea is for the > API to be sufficiently abstract that various different implementations can be > plugged in. In particular, there would be one that just writes the metric > data to a file, and another that sends metrics to Ganglia. It would also be > possible to plug in an implementation that can support high-frequency (say, > per-second) sending of fairly large amounts of data (up to hundreds of > metrics) across the network. > I'd be very interested in people's thoughts about what the requirements > should be for such an API. > - David Bowen -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
