---------------------------------
Summary: Create Grafana dashboard for tracking system wide deletion
Key: HDDS-11512
URL: https://issues.apache.org/jira/browse/HDDS-11512
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
Data deletion in Ozone must flow through three different components
asynchronously, and it can be difficult to tell what stage it is in when space
has not yet been reclaimed. This Jira is to add a Grafana dashboard for end to
end deletion tracking across the whole system in one place. This should include
all the metrics described in HDDS-11511, in addition to total cluster space
usage from SCM.
For each component, another line should show the aggregate deletion amount
across all threads. For example, if there are 3 OM key delete threads and they
each deleted 10 keys at a given point in time, this line would show 30 keys
deleted at that time.
The dashboard should support specifying a datanode host to focus on the
progress of its deletion threads and its space usage per volume.
