[google-appengine] Re: inconsistent daily "frontend instance" costs

['Ernesto Contreras Pinon' via Google App Engine]

Each time your instances are started, they accrue instance hours 

 up 
to 15 minutes after the last request or 15 minutes after the instance is 
shut down. This behavior can explain instance hours accumulating 
 depending on how the 
requests are received by App Engine. Which type of scaling is set up for 
your application? Also which environment are you using (Flex/Standard)?

 still, every day i'm being charged ~$0.50, which means 10 extra hours. 
 That's almost 50% more than what's displayed.
 Also this issue only started very recently, I haven't had any issues 
 with this for the past 3-4 months.

[google-appengine] Re: inconsistent daily "frontend instance" costs

[Zvika Ben-Haim]

I have a very similar situation: 
- Limited to one F1 instance per project
- Looking at App Engine -> Instances -> Billed instances shows under 1 
instance at each moment, except for brief moments with two instances
- Yet Billing consistently charges me for several hours of frontend 
instances.

Tried resolving this via Google's support chat and they were unable to 
explain the discrepancy, their only suggestion was to purchase a "technical 
support package" which I doubt will help either.

Also tried deleting old versions (even though they were not running any 
instances).. did this a week ago, still getting charged.

This is quite annoying! Anyone have a suggestion?

Finally managed to make it go back to zero. Not sure which of the things I

I also optimized my app more and changed max_concurrent_requests

If you believe that you are being overcharged, I will recommend to create a 
support case with Google Cloud [1] for a deeper investigation. Please 
include all the details mentioned on this thread in the case and our Google

 The annoying part is that there seems to be no way to actually see the

 Is 
 there some API that gives access to that which I'm missing?

According to the official documentatio:
"Setting the maximum to 1 instance **usually** keeps your instance hour 
usage within the free tier."
However, please consider the important note:
"*Important:* App Engine applies the max_instances setting on a best effort 
basis. *In some circumstances, App Engine may briefly exceed the limit you 
specify.*"

[google-appengine] Re: inconsistent daily "frontend instance" costs

[Ehsan Kia]

None of the older versions are running, and I have an instance limit, but I 
still went ahead and deleted all the older versions. It's still happening.

I'm pretty convinced AppEngine is miscalculating my usage...

 I remember years ago it was possible to see the quota usage for

 Is there any way to debug where these costs come from and what my usage

Hello, 

Did  you stop serving the previously deployed versions of your GAE 
Application ?  If you no longer require these versions you can delete the 
version by following our public official documentation [1] [2]:

[google-appengine] Re: inconsistent daily "frontend instance" costs

[Ehsan Kia]

I don't think so, since again, the billing section on the AppEngine 
Dashboard  generally takes that 
into account, in my experience. But yes I've also verified that it is F1.
Again last night, when I wrote this email at 3am, the counter was at 24.5h 
right before the reset, but today I see a charge of $0.55.

The annoying part is that there seems to be no way to actually see the 
finalized quota usage to verify these costs. How can I make sure what 
Google is charging me is the right amount if I can't even see the usage? Is 
there some API that gives access to that which I'm missing?

[google-appengine] Re: inconsistent daily "frontend instance" costs

[Jean-Daniel FISCHER]

Hello, maybe it is due to your instance class. If I remember correctly one 
hour of an F2 is billed as two hours and F4 is billed as 4 hours.  I think 
the base idea is that one hour represents one hour of F1. There is this 
part of the doc that helped us understand our cost when we are facing the 
same question:

" *Important:* When you view your bill 
, you will not see 
the names of the individual instance classes in your billing line items. 
Instead, you see instance hours from the "B" classes reported as "Backend 
Instances", and instance hours from the "F" classes reported as "Frontend 
Instances". The bill will apply the appropriate multiple of instance hours 
for each instance class you use. For example, if you use an F4 instance for 
one hour, you see "Frontend Instance" billing for four instance hours at 
the F1 rate."
