Don't bother with StackDriver if if gives ANY issues. They've been in a weird state since the acquisition 2 years ago. (But I still hope it will be fixed and become a great service at some point in the future).

Use datadog instead. It does all the monitoring things and it works flawlessly.

Also, try signalfx for the comparison. It's a good copycat but it lags behind in advanced integrations.
