I have a similar request. We have high priority and low priority processes that are running on GAE.  Although we always try to leave plenty of quota as overhead, if something goes wrong (e.g., a run-away process), we want to be able to shut down the non-critical processes *before* we hit a quota limit.

+1 for this request

My system integrates with the GAE and being able to programatically check the percentage of requests used toward quota would be extremely useful.

Is there still no way to read current API usage. Especially 500 writes per day is pain in the a** :(

DDofborg, What is the use case for more then 500 writes per day? have you attempted to implement batching (for user permissions)? we recently implemented a batching solution for user permissions in which you can do 30 writes for the cost of one, and see significant performance gains. https://developers.google.com/analytics/devguides/config/mgmt/v3/mgmtUserPermissions#batching

Also you can apply for a quota increase, and if you meet the criteria you will likely get an approval: https://developers.google.com/analytics/devguides/config/mgmt/v3/limits-quotas?hl=en

In our case it's for a referrer spam killing tool (https://www.adwordsrobot.com/en/tools/ga-referrer-spam-killer). We need to add 35 filters to each view. We are hitting the limit very often. I don't think batching will help here, because it 35 writes per view for one account.

I already applied for a quota increase, so that is in progress.

I still think having insights in your usage is a good idea, because you can notify user before the quota problems occur. Any plans for that? Or is there another way? Like via Developers Console?
