贴一下 nginx 容器的配置,以及 nginx 的配置信息。然后建议将 Nginx 容器的网络模式改为 HostNetwork 试试。

你都说高峰期接口耗时日志明显增加,建议先查后端逻辑。
有可能后端因为某种原因响应很慢,导致 Nginx worker 无法快速响应前端,直到把 worker 全都占满。 如果是这种情况的话,问题出在后端,调高负载均衡配置不解决根本问题。 |

@silencechengk 需要再看一下宿主机和 Nginx 容器内 ulimit 和最大打开文件数设置,如果这两个参数小于 worker_connections 值,调大 worker_connections 参数无意义。

宿主机的 ulimit 参数建议要大于容器,小于就没有意义。另外你也打印了 upstream_response_time 日志,可以根据日志筛选接口的响应时间,对比一下其他时间段。如果发现高峰期响应时间明显上升,那就是后端代码的问题,如果发现变化不大,那就是 nginx 的问题

worker_connections are not enough 没遇到过,也没设置过
从”流量早高峰时,接口耗时增多,前端请求 pending“分析 1. 频繁创建销毁线程,导致 GC 频繁,一般是 Yong GC ,导致耗时边长,可以监控下 GC 频率 2. 有线程共享资源竞争情况,导致线程等待,导致耗时变长 这两点都是从减少接口耗时,及时释放资源,来解决连接数不足的问题 |
