**What is the feature you want to add?** 北极星负载均衡的基本原理是,先通过一些路由规则获取一批可用实例节点列表,然后再通过负载均衡从中选取一个节点。支持的负载均衡策略有权重随机、权重hash。实例的权重通过 webUI 配置。 我们希望能通过实例访问的成功率,动态调整该权重。成功率高的实例分配较高的权重,成功率低的实例分配较低权重。 **Why do you want to add this feature?** 我们是多地区环境,选取可用实例节点列表时优先选择同园区实例;同园区下无可用实例时,向上降级,选取同地区、跨园区的可用实例。由于跨园区了,可能访问会超时或失败,此时希望将流量更多的分配给访问成功率较高的实例。 **How to implement this feature?** 客户端记录实例调用次数、成功次数,并使用 EWMA 指数加权平均之类的算法计算调用成功率。 在负载均衡前将成功率乘以实例原本的权重作为新的权重,之后再做负载均衡...

服务列表及实例页面只支持按单选标签查找,期望支持多选

1. 限流资源新增【CPU使用率】类型 2. 选择CPU使用率类型时: - 限制只能单机限流 - 阈值变为【CPU使用率阈值】,单位变为%;增加【滑动窗口精度】配置选项 - 限流方案变为【自适应】
