------------------------------------
Summary: Add JM metric which shows the restart duration
Key: FLINK-4202
URL: https://issues.apache.org/jira/browse/FLINK-4202
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.1.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.1.0
It is convenient for users to have a metric which tells you how long the
restarting of a job has taken.
I propose a to introduce a {{Gauge}} which returns the time between
{{JobStatus.RESTARTING}} and {{JobStatus.RUNNING}}. If the job was not
restarted (initial run), then this metric will return {{-1}}.
