Load Balancer outputs weird latency

[bluage_nakayama]

Hi,

I have a question about ALB and timeouts.

We have a web system that utilizes an Application Load Balancer (ALB) connected to our GKE cluster. We have enabled logs and observed something unusual. We configured the timeout value for the backend service to be 30 seconds, but the ALB log indicates that the latency exceeded 30 seconds, showing a value like "162.824886." How could this happen?

The "httpRequest.status" is 200, so the requests seem to be processed correctly.

Thank you so much!
