适用于

StorageGRID 11.X 和 12.X

说明

StorageGRID 遇到异常多的活动代理删除请求和 HTTP 会话。  

可通过以下方法进行确认:

1.从 GMI --> 支持 --> 指标 --> Prometheus 界面(以 /metrics/graph 结尾的链接)

2.还可以配置为自定义警报,以便您可以在 GridManager UI 上看到警报

查找以下内容:

storagegrid_private_serialization_active_proxy_delete_object_requests 已超过 1500
storagegrid_http_sessions_incoming_currently_established{service="ldr"} 已超过 15,000

请注意,这些条件也可能会触发与打开文件描述符 (FOPN) 相关的警报,但本文中引用的问题的主要指标是上述两个指标。  如果您没有看到这些症状,请使用 FOPN KB  进行进一步故障排除。

影响:这种情况可能会停止删除操作,可能导致应用程序中断并导致 504 错误。依赖于删除操作的应用程序可能会遇到重大中断,应根据对客户的影响来定义案例优先级。 

原因:通常由网络问题触发,例如站点隔离或交换机/路由器/防火墙更改。
