ALB监控项 - 负载均衡

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，您可以通过ALB监控项指标来实时监控分析和排查问题。本文为您介绍ALB的监控项指标。

背景信息

当您调用云监控API时，需要获取ALB的Namespace、Period、MetricName和Dimensions。

Namespace为acs_alb。
Period默认为60秒，也可以为60的整数倍。
参数中的Dimensions为JSON字符串，例如：[{"loadBalancerId":"alb-t93aj3yndojot5****"}]。Dimensions中的loadBalancerId为ALB实例的实例ID。

ALB监控指标

下表的MetricName列中，没有DualStack_前缀的监控项不区分IPv4和IPv6指标，表示ALB实例总指标。
- 对于IPv4实例，不带DualStack_前缀的监控项代表该ALB实例IPv4指标。
- 对于双栈实例，不带DualStack_前缀的监控项代表该ALB实例IPv4指标和IPv6指标之和。
下表的MetricName列中，带有DualStack_前缀的监控项，表示该监控项会分别展示IPv4指标和IPv6指标。
- 对于IPv4实例，每个带有DualStack_前缀的监控项中IPv6指标的值显示为0.0，IPv4指标的值代表该ALB实例的指标。
- 对于双栈实例，每个带有DualStack_前缀的监控项会分别展示IPv4和IPv6指标，分别代表该ALB实例IPv4指标和IPv6指标的值。

下表中，“-”表示不涉及DualStack_前缀的监控项，不支持分别查看IPv4指标和IPv6指标。
