Checking task status

[Space4444]

Hello. Suppose I started a worker, then started a python script wich kiqed a task. And then stopped that python script. Then started another python script. How can I properly determine in that script if the task is running or was canceled due to worker shutdown?

I can obtain workers' PIDs after starting up them by running a CLI command to search for processes with name "taksiq", then save these PIDs to a file and then after some time I can run the same command to check if all of the workers are still running. And if some of them were stopped then the task may be canceled. But I wonder if there is a better way?

P.S. I'm using Redis
