How to check running job on self-hosted Azure DevOps Agent on Linux via bash

Question

I have installed the Azure DevOps agent on my Linux Ubuntu (Ubuntu 20.04.3 LTS) machine - https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/v2-linux?view=azure-devops.

Now I want to write a script, which will check if there is some job (pipeline) running on an agent.

Is it possible to somehow check whether there is a job running on the agent via bash on Linux, where is the agent installed? Without API calls to Azure DevOps.

Answer 1

I found a solution by reading the status of the agent service:

Go to folder where you installed the agent and run -

./svc.sh status | tail -n1 | grep -c -e "Running"

1. Get the agent status
2. Get the last line
3. Check if the last line contains the word Running. If not, the return code will be 0, and you know, that there is not any job currently running on Agent. Otherwise, the return code of the command will be >=1.
