tomscut opened a new pull request #4035: URL: https://github.com/apache/hadoop/pull/4035
JIRA: [HDFS-16488](https://issues.apache.org/jira/browse/HDFS-16488). 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. -- This is an automated message from the Apache Git Service.
