> I export the metrics to the logfile via Slf4jReporter(https://issues.apache.org/jira/browse/FLINK-4831), and found that there are some checkpoint metrics that are not described in the document, so I added.
> {noformat}
> //Number of total checkpoints (in progress, completed, failed)
> totalNumberOfCheckpoints
>  //Number of in progress checkpoints.
> numberOfInProgressCheckpoints
> //Number of successfully completed checkpoints
> numberOfCompletedCheckpoints
> //Number of failed checkpoints.
> numberOfFailedCheckpoints
> //Timestamp when the checkpoint was restored at the coordinator.
> lastCheckpointRestoreTimestamp
> //Buffered bytes during alignment over all subtasks.
