Problem you have encountered:

I am trying to create an uptime check in Google Cloud Platform using the gcloud command line client. This is an example:

gcloud monitoring uptime create 'example uptime check' --resource-labels=host=...,project_id=... --resource-type=uptime-url --protocol=https --port=443 "--path=..." --request-method=get --validate-ssl=true --status-codes=200 --matcher-type=contains-string "--matcher-content=..." --period=5 --timeout=30 --user-labels=instance-group=production,instance-type=authentication

This generally works, i.e. the uptime check is created and no errors are reported. However, my user labels are silently ignored.

What you expected to happen:

User labels added to the uptime check.

Steps to reproduce:

See above.

Other information (workarounds you have tried, documentation consulted, etc):

Running the command with --log-http --verbosity=debug shows that the user labels are captured correctly, but omitted in the request to the Monitoring API. When I add the user labels to the API request and send the request manually then the user labels are added correctly.

I have also tried to add user labels to existing uptime checks via gcloud monitoring uptime update, but that also did not work, so it seems to suffer from the same issue. However, I have not confirmed that it is indeed the same issue.
