checkpoints
[ https://issues.apache.org/jira/browse/FLINK-7626?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hai Zhou_UTC+8 updated FLINK-7626:
----------------------------------
Description:
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.
lastCheckpointAlignmentBuffered
{noformat}
was:
