Cloud Logging 使用 LogEntry 数据类型表示日志，
定义了所有日志条目的通用数据以及
Google Cloud 服务可能包括：如需了解详情，请参阅 LogEntry
和 Fleet Engine API Logging 集成。
较长的日志会拆分为多个日志条目。请参阅处理拆分 日志。
日志条目示例
以下示例展示了 UpdateVehicle 日志的 LogEntry。RPC
请求和响应位于 jsonPayload 字段中。
{
"insertId": "c6b85fbc927343fc8a85338c57a65733",
"jsonPayload": {
"request": {
"header": {4},
"updateMask": "deviceSettings",
"vehicleId": "uniqueVehicleId",
"vehicle": {2}
},
"response": {
"name": "providers/example-project-id/vehicles/uniqueVehicleId",
"availableCapacity": 2,
"state": "VEHICLE_STATE_OFFLINE",
"maximumCapacity": 2,
"vehicleType": {1},
"supportedTrips": {1}
},
"@type": "type.googleapis.com/maps.fleetengine.v1.UpdateVehicleLog"
},
"resource": {
"type": "fleetengine.googleapis.com/Fleet",
"labels": {2}
},
"timestamp": "2021-01-01T00:00:00.000000000Z",
"labels": {2},
"logName": "projects/example-project-id/logs/fleetengine.googleapis.com%2Fupdate_vehicle",
"receiveTimestamp": "2021-01-01T00:00:00.000000000Z"
}
如果返回 RPC 错误，系统会清除 responseVehicle 字段，并在 jsonPayload 中设置和填充 errorResponse 字段。
{
"insertId": "c6b85fbc927343fc8a85338c57a65733",
"jsonPayload": {
"errorResponse": {
"httpStatusCode": 404,
"code": "NOT_FOUND",
"message": "No entity with id invalidVehicleId exists"
},
"@type": "type.googleapis.com/maps.fleetengine.v1.UpdateVehicleLog",
"request": {
"vehicle": {3},
"updateMask": "deviceSettings",
"vehicleId": "fakeVehicleId",
"header": {4}
}
},
"resource": {
"type": "fleetengine.googleapis.com/Fleet",
"labels": {2}
},
"timestamp": "2021-01-01T00:00:00.000000000Z",
"severity": "ERROR",
"labels": {2}
"logName": "projects/example-project-id/logs/fleetengine.googleapis.com%2Fupdate_vehicle",
"receiveTimestamp": "2021-01-01T00:00:00.000000000Z"
}
