 SourceConfig | `object` | **Required.** The datasource's Logstore name. Triggers periodically subscribe to data from the Logstore to Function compute.
 
 JobConfig | `object` | **Required.** There are two configurable properties, one of which is MaxRetryTime, which represents the maximum number of attempts allowed if the logging service triggers a function execution. The other is TriggerInterval, which indicates the interval at which the logging service triggers the execution of the function.
-LogConfig | `object` | **Required.** There are four configurable properties. The first is Project, which represents the log service Project name. The second is the Logstore, which means that when the trigger function is executed, the resulting log will be logged to the Logstore. The third is Enable, which indicates whether the trigger is enabled. The fourth is an optional property, FunctionParameter, which is itself an object that, when the event fires, is sent to the function along with its contents.
