How can I check how many instances of a Google Cloud Run container are running?

Question

Google Cloud Run lets me set a concurrency for a given container, which is how many concurrent requests it will service before a new container is spun up.

How do I actually check how many containers are running at any given time? The web interface mentions which services are running but not how many of them there are, and the same is true when I do gcloud beta run services (list|describe).

Answer 1

The Billable instance time metric can give you a sense of how many instances were running.For example, if a Revision with 2 container instances has been continuously serving traffic in the last minute, the value is 2s/s

Alternatively, you can export your logs to BigQuery. Each log entry has an instance ID as label (see docs) that you could group by and count.
