App Engine nginx request logs, does it include response time

[Jyotsna Bhati]

In GAE nginx request logs,jsonPayLoad have property 'latencySeconds'

 jsonPayload: {

  appLatencySeconds: "0.225"   

  latencySeconds: "0.226"   

  trace: "7a10c9ee95f1ccec75949404b1859439"   

 } 

I am struggling to find out whether the responceTime is subset of the latencySeconds. 

I know,latency and Response Time differs in what terms, but I read somewhere that the GAE calculate the latency, calculating turn around time when the request hit to load balancer app engine process and response sent from load balancer.

Hello,

The information in the nginx request logs does not take into account the load balancer. "jsonPayload.latencySeconds" corresponds to the request time starting from when Nginx reads the first byte until Nginx sends the last byte of the response body and it differs from a full response time as it is only measuring upstream server response time.
