Question: why grep busy in graceful shutdown #47

Closed flovilmart closed 3 years ago

flovilmart commented 3 years ago

Hi! Thanks for maintaining this project.

When integrating, one of my coworkers came with this question:

#!/bin/bash

# Find Pid
SIDEKIQ_PID=$(ps aux | grep sidekiq | grep busy | awk '{ print $2 }')

Why grep busy? Could this possibly not match sometimes? If so, would need to be handled below

Any chance you can clarify for us the need for busy?

thanks!

Hi @flovilmart, Thanks for pointing out. This code is an example script to find the PID managing the sidekiq process, the busy is a way to select the right one. If you have a better way I'm happy to change the docs, even add it into the lib. Here is my output in console:

Gotcha! Thanks for the explanation.
