---------------------------------
Summary: Exports ozone metrics to prometheus
Key: HDDS-846
URL: https://issues.apache.org/jira/browse/HDDS-846
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: Ozone Manager, SCM
Reporter: Elek, Marton
Assignee: Elek, Marton
As described in the parent issue, as of now we use a java agent based dark
magic to get all the hadoop metrics values in prometheus http format.
The format is very simple
(https://github.com/prometheus/docs/blob/master/content/docs/instrumenting/exposition_formats.md)
and it would be easy to implement a simple form of prometheus servlet.
With publishing the metrics with an included servlet the k8s deployment could
be more simple and will be easier to provide ways to run ozone in cloud native
environments.
