Function Description
On the Task Attribute tab page, you can set Task Priority and Log Level Setting for scheduled tasks, as shown in the following figure.

Task Priority | You can set the execution priority of scheduled tasks.If the number of threads is insufficient, tasks with higher levels in the queue are executed first. |
Log Level Setting | You can set the log level for scheduled tasks separately. |
Task Priority
You can set the execution priority for scheduled tasks, as shown in the following figure.
1.If the number of threads is insufficient, tasks with higher levels in the queue are executed first. If multiple tasks have the same priority, the tasks earlier entering the queue are executed. Subtasks inherit the priority of the parent task.

There is a risk that low-priority tasks may never get their turn.
2.The task execution priority is divided into five levels: Highest, High, Medium, Low, Lowest. The default setting is Medium, with non-empty validation; the default upgrade starts from the Medium level.
3.Changes in the execution priority of scheduled tasks take effect on task instances that are about to enter the queue only, without affecting running/queuing task instances.
Log Level Setting
You can set the log level for each scheduled task separately to meet different requirements such as log viewing, task debugging, and troubleshooting, as shown in the following figure.
1. Output logs are those related to the reading and writing processes of scheduled tasks, including error and exception logs.
2. This function is disabled by default. When it is disabled, logs are recorded based on the global log level, which is set to WARN by default.
3. The modified log level takes effect during the next execution of the task; for specific log output details, see Running Log Introduction.
4. You can select ERROR, WARN, or INFO in Log Level Setting.
Rank of log levels by severity (from highest to lowest): ERROR > WARN > INFO
Rank of log levels by detail (from simplest to most detailed): ERROR < WARN < INFO
Log Level | Description |
---|---|
ERROR | Indicates an error that causes the service unavailable. |
WARN | Indicates a warning of potential issues that do not cause unavailability, typically used for alerts. |
INFO | Indicates general information about the running status or important events. |
5. If the log level configuration of the task has been manually modified, when the global log level configuration is modified, the global log level will not affect the task whose log level has been manually modified.
