How to verify if multiple containers getting used

Build Environment
1

We have configured multiple containers in CircleCI to achieve parallelism and avoid jobs to wait in queue. I am using resource_class key in my job to specify container’s resources to leverage multiple containers. Not sure if that is the correct way of doing it. Is there a way to verify if I am using multiple containers or not as my jobs are still getting Queued for few seconds.

It sounds like you’re looking to set the parallelism parameter in your job definition – more info available here and here.

resource_class is a paid feature intended to control the level of resources (memory and CPU) allocated to a container – more info here.
