    负载均衡：查看NLB监控信息

    更新时间：Dec 05, 2023

    当您遇到网络型负载均衡NLB请求超时、流量限速等网络连接问题，或者需要了解NLB的负载、性能等情况时，您可以利用云监控功能查看NLB资源的运行状态和各个指标的使用情况，方便快速定位问题。您可以通过控制台、API、SDK方式来查看NLB的监控信息。

    通过控制台查看监控

    1. 登录网络型负载均衡NLB控制台。

    2. 在顶部菜单栏，选择NLB实例所属的地域。

    3. 在实例页面，您可以选择以下任意一种方式查看监控。

      • 在实例列表页面直接查看

        1. 在实例页面，找到目标实例，在监控列单击monitor。

        2. 在弹出的监控信息面板，切换实例、监听、VIP（可用区）页签，查看监控信息。

      • 在实例详情页面查看

        1. 在实例页面，找到目标实例，单击实例ID。

        2. 在实例详情页签，单击监控图表页签。

        3. 在监控图表页签，切换实例、监听、VIP（可用区）页签，查看监控信息。

      说明

      • 关于NLB实例监控项详细说明，请参见NLB监控项说明。

      • 系统默认为您展示最近1小时内的监控数据，您可以选择查看3小时内、6小时内或12小时内的监控数据，还可以选择自定义，自定义需要设置查看的时间段。

      • 开启自动刷新后监控图表每分钟自动刷新监控数据。

    通过API查看监控

    介绍如何通过云监控API查看网络型负载均衡实例的监控项和详细监控数据。

    通过API查看监控数据流程，如下图所示。monitoring

    流程说明如下：

    1. 查看数据命名空间Namespace。调用DescribeProjectMeta接口查询云监控中NLB的数据命名空间Namespace。

    2. 可选：查看已有监控项。调用DescribeMetricMetaList接口查询云监控开放的时序类指标监控项描述或直接查看监控项说明，更多信息，请参见NLB监控项说明。

    3. 查看指定监控项的监控数据。

      • 调用DescribeMetricLast接口查询NLB指定监控对象的最新监控数据。

      • 调用DescribeMetricList接口查询NLB指定时间段内监控对象的时序指标监控数据。

    DescribeProjectMeta

    调用DescribeProjectMeta接口查询云监控中NLB的数据命名空间Namespace，详情请参见DescribeProjectMeta。

    1. 登录OpenAPI开发者门户。

    2. 将请求参数中报警产品标签过滤Labels的值设置为[{"name":"product","value":"NLB"}]，其他参数保持默认值，然后单击发起调用。

      查看请求示例

      http(s)://[Endpoint]/?Action=DescribeProjectMeta
&Labels=[{"name":"product","value":"NLB"}]
&<公共请求参数>

    3. 根据返回参数，获取云监控中NLB数据命名空间Namespace的值为acs_nlb。
