The Balancer access log provides information about requests received at the balancer level. Since most customers use shared load balancers, Varnish logs are only available using the log stream feature and cannot be downloaded from either the Cloud Platform interface or your infrastructure.
Each of the items in the balancer access log is noted in the following table, along with its description:
