Bharath Vissapragada commented on HBASE-17448: ---------------------------------------------- [~ckulkarni]/[~apurtell] Are these ZK metrics exposed anywhere? Doesn't look like it to me. I was looking to add a metric for a ZK operation and stumbled up on this. > Export metrics from RecoverableZooKeeper > ---------------------------------------- > > Key: HBASE-17448 > URL: https://issues.apache.org/jira/browse/HBASE-17448 > Project: HBase > Issue Type: Improvement > Components: Zookeeper > Affects Versions: 1.3.1 > Reporter: Andrew Kyle Purtell > Assignee: Chinmay Kulkarni > Priority: Major > Labels: patch > Fix For: 1.4.0, 1.4.1, 1.4.2, 2.0.0 > > Attachments: HBASE-17448-branch-1.patch, HBASE-17448.patch, > HBASE-17448.patch > > > Consider adding instrumentation to RecoverableZooKeeper that exposes metrics > on the performance and health of the embedded ZooKeeper client: latency > histograms for each op type, number of reconnections, number of ops where a > reconnection was necessary to proceed, number of failed ops due to > CONNECTIONLOSS, number of failed ops due to SESSIONEXIPRED, number of failed > ops due to OPERATIONTIMEOUT. > RecoverableZooKeeper is a class in hbase-client so we can hook up the new > metrics to both client- and server-side metrics reporters.
