Monitor and control Flink job lifecycles from the Job O&M page in Operation Center. This page shows the current status of each job and lets you start, stop, snapshot, or delete jobs.
Prerequisites
Before you begin, ensure that you have:
-
Access to the target workspace in the Realtime Compute for Apache Flink console
-
Permissions to view and manage job status. If other Alibaba Cloud accounts or Resource Access Management (RAM) users need access, grant them the required permissions. For more information, see Authorize users in the development console.
View job status
-
Log on to the Realtime Compute for Apache Flink console.
-
In the Actions column of the target workspace, click Console.
-
In the left-side navigation pane, choose Operation Center > Job O&M.
-
Find the target job and check its current state in the Status column. The following table describes each job status.
Category Status Description Transitional Starting The job is starting. Stable Running The job is running normally. For stream jobs, the Health Score column shows overall job health. A score below 100 indicates a potential issue — click the score to run an intelligent diagnosis, which identifies the cause and suggests corrective actions. For more information, see Intelligent job diagnosis. Stable Finished The job completed successfully. Batch jobs and bounded stream jobs enter this state upon completion. Stable Stopped The job was manually stopped. This state is set after you click Stop. Failed Failed The job encountered an error and stopped running. A job in Failed status is automatically flagged as abnormal.
