[jira] [Commented] (HBASE-20904) Prometheus /metrics http endpoint for monitoring integration

["Nick Dimiduk (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-20904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17158524#comment-17158524 ] 

Nick Dimiduk commented on HBASE-20904:
--------------------------------------

Apologies for arriving late to the discussion, it appears a fair bit of development has already happened. However, I'm concerned -- why would we build this ourselves when there exists [a tool provided by the prometheus project|https://github.com/prometheus/jmx_exporter] for exporting JMX beans? I have not tried it, but I have had very good success using [a tool for exporting JMX beans over http/json|https://jolokia.org] that appears to function identically. Why not avoid writing all the code and instead document use of the existing agent?
