Re: [google-appengine] Re: App Engine doesn't downscale when CPU utilisation is below target_utilization

[Harshit Dwivedi]

Thanks but this seems to be available only for the Standard environment.
I'm currently using Appengine in the flex environment.

The link to the article “Introducing headless Chrome support in Cloud

I inquired the blog administrators whether it will be republished and you

Re: [google-appengine] Re: App Engine doesn't downscale when CPU utilisation is below target_utilization

['Diogo Almeida' via Google App Engine]

Other than the parameter you are already using, I recommend you check how 
auto scaling services use dynamic instances 

 
and the parameter you can use in the app.yaml.

[google-appengine] Re: How to add new domain to app engine

['Diogo Almeida' via Google App Engine]

I just tested on my end and it seems that “projektecommerce.pl” is now 
mapping to your application.

Note that Google Groups is intended only for discussions about the Google 
Cloud Platform products. For issues like the one you reported here, in case 
additional investigation is needed, you will need to file a case instead

[google-appengine] Re: Nginx error

['George (Cloud Platform Support)' via Google App Engine]

502 (BAD GATEWAY) is returned by nginx if it fails to contact your service. 
This usually happens if your app stopped listening, when instance has been 
shut down or did not start. 

Investigation progress depends on information such as: what app engine 
service is affected by this issue, name of services, what time the errors 
started appearing. A simple fix, if you have deployed a new version 
recently, would be rolling it back. Some of the needed information items 
are of private nature, and should not be posted in a publicly accessible 
forum. You are therefore encouraged to open an issue, with more relevant 
information, in the Public Issue Tracker , 
and set communication to "private", prior to posting private or sensitive 
information.

Re: [google-appengine] Re: App Engine doesn't downscale when CPU utilisation is below target_utilization

[Harshit Dwivedi]

Thanks George for the explanation.
Is there a way I can tweak the autoscaling params for my appengine flex
deployment?

As far as I can see, it only allows me to modify the scaling based on the
CPU utilization.

[google-appengine] Re: How do I calculate how much AppEngine is costing me?

[Jasmine Sultanah]

Thanks Diogo. I have read all these links. My question is how do I find out 
how many cores per hour i'm using, how much memory per hour and how much 
persistent disk. the app is already running and I can see the dashboards in 
AppEngine. For example in AppEngine, my memory usage is 800MiB each 
minute,my instances remain at 2, CPU usage is about 5% (is this CPU usage 
of combined CPU for two instances?), my write Disk bytes is 50KiB a 
minute.  How do I translate this information into number of cores per hour, 
persistent disk and memory per hour. thanks

[google-appengine] setting headers - X-Frame-Options

Hi,
I am trying to set X-frame-options headers.

I added the following in the appengine-web.xml





 

It is all fine, except for one case.

For example, if I am running local and type
http://localhost: :  Then the headers are not added to the response

However, http://localhost:/index.html, the headers are added to the
response

How can I add the headers in the response for the case '
http://localhost:'
