-----------------------------
Summary: Support for smart querying of our published jmx per
server over http+json
Key: HBASE-16800
URL: https://issues.apache.org/jira/browse/HBASE-16800
Project: HBase
Issue Type: Improvement
Components: metrics
Reporter: stack
Assignee: stack
We currently expose our jmx metrics via a json dump in a servlet at /jmx. You
get all or nothing (You can add a '?description=true' to get a description for
each metric published but that is it).
A means of being able to query by metric or by a set of metrics would make
graphing easier to do, especially over http dumping json. In particular, our
[~appy] is trying to put up pages that give insight into current state of
replication.
Related, HBASE-11747 ClusterStatus is too bulky, is about how whenever we need
a metric 'exposed', our only means is by bulking out the heartbeat adding
payload on each message we send the server (In the issue, w/ 1M regions, each
RS is sending 100MB of 'status' every second). We need to undo metrics
collection from clusterstatus function
Bonus if able to compress/cache payloads, security, etc.
