How can I see request count (not rate) for a Google Cloud Run application?
May 12
I deployed a Google Cloud Run service running in a docker container. Out of the box, it looks like I get insight into some metrics on the Metrics tab of the service page such as Request count, Request latencies and more. Although it sounds like request count would answer my question, what I am really looking for is insight into adoption so that I can answer "How many visits to my application were there in the past week" or something like that. Is there a way to get insight like that out of the box?
Currently, the Request count metric reports responses/second, so I can see blips that look like "0.05/s", which can give me some insight but it's hard to aggregate.
I've tried using the Monitoring > Metrics explorer as well, but I'm not seeing any data for the metrics I select. I'm considering hooking into Google Analytics from within my application if that seems like the suggested solution. Thank you!

I've realized it's quite difficult to have Metrics Explorer give you a straight answer on "how many requests I received this month". However, it's possible:
Go to Metrics Explorer as you said, choose resource type "Cloud Run Revision" (cloud_run_revision) and you'll see "Request Count" (run.googleapis.com/request_count) metric:
Description: Number of requests reaching the revision. Excludes requests that are not reaching your container instances (e.g. unauthorized requests or when maximum number of instances is reached).
Resource type: cloud_run_revision
Unit: number Kind: Delta Value type: Int64
Then, choose Aggregator: None, and click Show Advanced Options. In the form, choose Aligner: sum (instead of default "Rate" default). You now should be able to see total request count per minute:
Now if you change "Alignment Period" to "10 minutes", you'll see one data point for every 10m (sadly, there seems to be a bug that says X req/s, but that's more like X reqs/10m in this case):
If you collect enough data, you can change "Alignment Period" to "Custom" and set 30 days, then update your timeframe on the top to 1 year and see monthly request count.
This does not show sums of all Alignment Periods (I think that part is up to you to do manually, maybe possible via the API), but it lets you see requests per month. For example, here's a service I've been running for some months and I set alignment period to 7 days, viewing past 6 weeks, so I get 6 data points on weekly request count. Hope this helps.
