> 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.
