Missing logs (for 12 hours) on Node.js Google App Engine Flexible Environment

[Marco Galassi]

We have noticed that a couple of days ago we have no logs for more than 12 hours.

The only logs we see in those 12 hours are vm.events that look something like this:

00:55:01.649
Health checks: instance=aef-[our-service]--v3-rf5g start=2017-09-29T22:52:00+00:00 end=2017-09-29T22:52:59+00:00 total=372 unhealthy=0 healthy=372

Before and after that time window, we have our regular logs.

We know for a fact that in that time window something has happened and that we should be seeing logs, as we have data in our database that corresponds to 

requests handled in that time window.

For now, we are just printing the logs using console.log

Is there any reason Google App Engine could not show logs?

Whatever idea is welcome

Hello Marco, 

There is no obvious reason why App Engine would process requests but not make the logs for those requests available. To get to the bottom of this please create a private issue and share at least your project-id and the affected time frame (with time zone).

Hi Yannick,

I think you gave me the wrong link because it bring me to "MOMA inside Google" that looks like something for Google Employees
