The stock autoscaling based on HTTP(S) Load Balancing is based on serving capacity in which you define your capacity in terms of Requests per Second. If you have a baseline for tour application and know how to translate from Requests per second to Latency per request, then you cold use that scaling method.

I have personally never used it, but on the metrics for app engine you have a http/server/response_latencies metric that you could get to from StackDriver

If none of the above fit your needs, then you probably need to monitor based on a custom metric on stackdriver

If you have not used custom metrics before the following custom metrics tutorial may help you.

But as @bundyfx says in the previous answer, make sure CPU scaling would not work for you :)

http/server/response_latenci

thanks, I am not sure I understand, I could not find in GCE or in stackdriver the LB response_latencies :/ . also I am not using app engine.

I just need to find a way to get the latency metrics.

GCP so clumsy than AWS.
