当您遇到应用型负载均衡ALB请求超时、流量限速等网络连接问题,或者需要了解ALB的负载、性能等情况时,您可以利用云监控功能查看ALB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ALB的监控信息。
通过ALB控制台查看监控
- 登录应用型负载均衡ALB控制台。
在顶部菜单栏,选择ALB实例所属的地域。
通过以下任意一种方式查看监控信息。
在实例列表页面直接查看
在实例页面,找到目标实例,在监控列单击。
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
在实例页面,找到目标实例,单击实例ID。在实例详情页签,单击监控图表页签。
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。
说明仅固定IP模式ALB实例支持查看VIP(可用区)相关指标监控项。若您需要设置ALB实例的VIP(可用区)指标报警规则请至云监控控制台,具体操作请参见设置ALB监控项报警规则。
如果是双栈ALB实例,您可以在监控信息面板左上角的指标类型下拉框中,选择全部指标、IPv4指标、IPv6指标来分别查看相关指标。
在监听页签,支持在监听下拉框中,选择该实例的其他监听,查看所选监听的指标;支持在维度下拉框中,选择监听、服务器组、转发规则及具体的服务器组ID和转发规则ID来分别查看相关的指标。
您可以通过设置时间来调整监控图表显示的时间段。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查看应用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。
