Java 8 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Java 8
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Java
8 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Java.

public interface LogService
LogService allows callers to request the logs for an application
using supplied filters. Logs are returned in an
Iterable that yields
RequestLogs, which contain request-level information and optionally
AppLogLine objects containing the application logs from the request.
