Over Quota Custom Message

[Hossein Amerkashi]

Hi,

Is there anyway to create a custom message for over-quota?

Thanks

If your app exceeds the free quota for a resource needed to initiate a request, such as the bandwidth quota or instance hours quota, users of the app will get a server error, such as a HTTP 503 error. For all other services, exceeding quota from a free app will generate a quota exception that your app can handle gracefully by showing a message to the users. The "App Engine Pricing" page [1] provides more related information. 

How would you like to configure your custom over-quota message? What information would you like to see in that message, more than what is provided with the 503 error? To whom would you like to see this message sent? 

It may prove worthwhile mentioning that for users of Firebase, there is more help with warnings, when certain percentages of quotas are passed. To track your Cloud Firestore costs, create a monthly budget in the Cloud Platform Console. Budgets won't limit your usage, but you can set alerts to notify you when you're approaching or exceeding your planned costs for the month. You may check the "Monitor Usage and Billing" page [2] for details.

Hi, Instead of a 503 error code, would like to create a custom, friendlier messages. Is that possible?

It is a lot of subjectivity involved here, in declaring a 503 error friendly or not: for the one who finds this information useful, the same string may well seem friendly. How would you formulate the 503 error friendlier? What extra information would you like to see included with this message? What is the use-case that requires extra information and re-formulation of the error message?

Hossein,

If we're talking about AppEngine standard, you can set the static file which will be served for particular sitations (over quota, timeout, etc): see "error_handlers" here: https://cloud.google.com/appengine/docs/standard/python/config/appref

Cheers,
Attila
