When a deployment is running, you can view the startup logs and operational logs of the deployment. This topic describes how to view the startup logs and operational logs of a deployment.
Background information
Item | Description |
Startup logs | After a fully managed Flink deployment is started, the startup logs of the current deployment are generated. The startup logs are generated from the time fully managed Flink is initialized to the time the JobManager is started. For more information about how to view the startup logs of a deployment, see View the startup logs of a deployment. Note The startup logs do not include scheduling logs. You can view the scheduling logs on the Events tab in the console of fully managed Flink. The scheduling logs contain issues, such as insufficient resources and insufficient IP addresses of the vSwitch. |
Operational logs | You can view the logs of JobManager and TaskManagers on the Diagnostics tab in the console of fully managed Flink or on the Flink web UI. For more information about how to view the operational logs of a deployment, see View the operational logs of a deployment. |

Logs are displayed by page. Each page can display up to 1 MB of logs and approximately 8,000 to 9,000 rows of logs.

If you cannot locate the issue based on the logs that are displayed on the first page, go to the next page.
