Summary: [SPS]: Expose metrics to JMX for external SPS
Key: HDFS-16488
URL: https://issues.apache.org/jira/browse/HDFS-16488
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: tomscut
Assignee: tomscut
Currently, external SPS has no monitoring metrics. We do not know how many
blocks are waiting to be processed, how many blocks are waiting to be retried,
and how many blocks have been migrated.
We can expose these metrics in JMX for easy collection and display by
monitoring systems.
For example, in our cluster, we exposed these metrics to JMX, collected by
JMX-Exporter and combined with Prometheus, and finally display by Grafana.
