How to check details of total denies of security rules in Google cloud?
How to check details of total denies of Firebase security rules in Google cloud? I have added the screenshot which is shown in the Firebase console. But it shows "
Use advanced analysis and alerting tools in Cloud Monitoring" But when I go to google cloud it does not have any details of that. I have also attached the screenshot of the Google cloud console which is opened when I click the cloud monitoring button in the Firebase console. 
There is currently nothing in the console that shows you why a request was denied by security rules. Feel free to file a feature request with Firebase support for that.
The best way to develop security rules (with Firestore) is to do that with the local emulator, which will give you more details about why a request from your test code was denied.
