logs in failure

[Kaiden0001]

Hi, how can i when processing failure in handlerOn get the last 100 lines of log ?
I want to send a message with the latest logs when my project crashes.

Hi, at the moment, Dagu provide the following three special environment variables:

• DAG_EXECUTION_LOG_PATH: The path to the log file for the current step.
• DAG_SCHEDULER_LOG_PATH: The path to the log file for the scheduler.
• DAG_REQUEST_ID: The unique ID for the current execution request.

As a workaround, you can search for files containing ${DAG_REQUEST_ID:0:8} in it's file name to retrieve all log files associated with the current DAG execution. But it is not a solution to access log files from the error step.

Accessing the log files from the error step sounds like useful capability in general. Let me explore potential ways to implement this, and perhaps we can look into how other workflow tools like Airflow handle similar situations.
