When a job is in the running state, you can view its startup and operational logs. This topic describes how to view these logs.
Background information
Type | Details |
Startup logs | Logs generated after a Flink job starts. These logs cover the period from the initialization of the Flink environment to the startup of the Job Manager. For more information about how to view startup logs, see View startup logs. Note Startup logs do not include scheduling logs. View the corresponding log information in management events. For example, issues such as insufficient resources or insufficient IP addresses for a vSwitch are related to scheduling. |
Operational logs | Logs for the Flink Job Manager and Task Managers are available on the job logs page and the Flink UI. For more information about how to view operational logs, see View operational logs. |
