publicinterfaceLogService
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.
Static Fields
DEFAULT_ITEMS_PER_FETCH
publicstaticfinalintDEFAULT_ITEMS_PER_FETCH
The number of items that each underlying RPC call will retrieve by default.
A LogQuery object that contains the various query parameters
that should be used in the LogReadRequest. If versions and majorVersionIds
are both empty, fetch will retrieve logs for the current running version.
