View all Fleet Engine logs

    type.googleapis.com/maps.fleetengine

View all RPCs to Fleet Engine that returned an error

    resource.type:"fleetengine.googleapis.com"

    labels.trip_id=~"trip_id"

Show logs for a vehicle over a specific time period

    resource.type="fleetengine.googleapis.com/Fleet"

    timestamp<"2020-09-24T21:00:00.000Z"

Note: Time values in this example are in Coordinated Universal Time (UTC) format. To specify a time zone, replace the letter Z at the end of the timestamp with +hh:mm or -hh:mm. For more information, see the Cloud documentation.
