# Timer measurement is used to measure the time between the start of an action executed by the
# Exec command and when the ILB services are running and reachable.
# ServiceCreationLatency measurement is used only for determining the moment when all of the
# ILBs are reachable. Since it reports time based on the initial creation of the service, and
# not from the start of the action, the measured time will not be shown.
