I've been looking at the cloud functions in my Firebase console, and I've notice for one day in the past month that I somehow reached 23k invocations. I initially thought to check because my billing said I was charged $0.02 for them.
I've searched high and low, inspected my billing, reports, logs. I can't seem to see what was called 23k times that day. Does anyone know where I can find this information.
Thanks!
Unfortunately there is no report that drill down a cost by each function for Cloud Function Billing. In order to see what functions are being invoked I would recommend that you keep some logs of usage of the functions, you can check how to setup logs in this Official Documentation.
It's important to note that this many invocations of your functions should not generate any billing to you, since as you can see on the Pricing Documentation for Cloud Functions, there is a free tier of 2 million invocations per month to all of your functions. So, for all your functions, you actually had at least 2 million invocations + 23.000 invocations that generated that $0.02 billing.
