What can I do to the apollo_query_execution_failed metric be counted? about apollo-prometheus-exporter HOT 2 CLOSED

Hello @rodrigomageste!

Apollo offers an executionDidStart hook that returns an object containing two properties:

• willResolveField - this refers to each field that is resolved as part of a query/mutation execution. It returns another function which will be called once that specific field has been resolved.
• executionDidEnd - this refers to the moment when the entire query/mutation execution has ended (successfully or not).

Apollo provides the docs for it here: https://www.apollographql.com/docs/apollo-server/integrations/plugins/#executiondidstart , more specifically in this paragraph:

Alternatively, it may return an object with one or both of the methods executionDidEnd and willResolveField. executionDidEnd is treated identically to an end hook: it is called after execution with any errors that occurred. willResolveField is documented in the next section.

The apollo_query_execution_failed counter will be increased when something happens during the execution of that query/mutation. Let's say that your entities are resolved from a database. When the connection to the database hangs or fails, then the execution will fail. This will end up being an execution error.

If you need a specific example, I'll be able to provide it in the upcoming days.
