How to get status of each task?

[Nathanrown]

I only use `nextflow log`` to get status of my pipeline, but how to get status of tasks in my pipeline ?

You can check the status of your tasks in your console output (even better with -ansi-log false), with the user interface of Nextflow Tower (if you run your Nextflow pipeline with Tower), or in the log files. If I run nextflow run nextflow-io/hello, for example, I will see something like this:

May-07 18:30:40.711 [Task monitor] DEBUG n.processor.TaskPollingMonitor - Task completed > TaskHandler[id: 1; name: sayHello (1); status: COMPLETED; exit: 0; error: -; workDir: /Users/mribeirodantas/work/3d/974e557ecaf9978f6d49966aac96ca]

in my nextflow.log file which shows the COMPLETED status for one of the tasks from the sayHello process.

Try nextflow log -f name,tag,duration,status RUN_NAME.

RUN_NAME is the name of your pipeline run, which is shown in the output (column 3) of nextflow log.

The format -f argument list the fields you want to see. (see all available output fields with nextflow log -l).

If your tasks are containerized, you can give your docker containers a name job_task_timeStarted then you can use docker ps or Docker Desktop UI to look at their live resource utilization.
