I wanted to know how many times cloud functions are getting triggered in my project.

1. Go to Google Cloud Console and open the Logs explorer

2. Click Show query. By default it showed the below logging query

Copycopy code to clipboard
1resource.type="cloud_function" 
2resource.labels.function_name="test_function1" 
3resource.labels.region="asia-south1"

Since i was to transfer all the logs related to Cloud Functions, i keep only the below condition

Copycopy code to clipboard
1resource.type="cloud_function"

3. Click More Actions or Actions and select Create Sink

4. It takes to Logging -> Logs Router. Here i fill following information

5. Click Create Sink

6. Go to bigQuery and execute a sample query like below to know how many times Cloud Functions were triggered in a day

Copycopy code to clipboard
1select count(resource.labels.function_name) as invocation_total, 
2resource.labels.function_name, 
3resource.labels.region
4from `<<project-name>>.gcp_logging.cloudfunctions_googleapis_com_cloud_functions_20220423`
5where textPayload = 'Function execution started' 
6group by resource.labels.region, resource.labels.function_name

Note: There will be one new table each day.
