How to log backend latency in Google Http Load Balancer and Stack Driver

Question

We have a running kubernetes cluster on GKE and we Google HTTP Load Balancer in front of it.

HTTP Load Balancer logs all requests and we can access them in stack driver logging. But latency is not logged, and I couldn't find a configuration for this. I want to get latency information for individual requests.

There are some latency reports in stack driver, so it should be logging in somewhere. Is it possible to access this information?

Answer 1

You can try to view your latency by using analysis reports. Although it is using Stackdriver Trace, this may be a possible solution.

Answer 2

Adding to @hachemon's answer, if you need a custom solution and the standar out-of-the-box Stackdriver Trace does not work for you, you can create your own custom solution and add it to your code using the Stackdriver Trace API.
