当前处理传入 HTTP 请求的 Apache 进程的百分比较高。Apache HTTP 性能可能会受到负面影响,传入 HTTP 请求可能必须等待当前请求完成才能进行处理。
不正常状态表示繁忙辅助进程的百分比当前较高。这可能是由于 Apache HTTP 服务器上进行的 HTTP 请求过多所引起的。
Apache 辅助进程处理传入 HTTP 请求。当前处理 HTTP 请求的辅助进程被视为“繁忙”,而等待的辅助进程被视为“空闲”。Apache 进程会继续使进程分叉或终止,直至它们满足为后续指令设置的要求。考虑使用以下设置调整进程配置:
ServerLimit
StartServers
MaxClients
MinSpareThreads
MaxSpareThreads
ThreadsPerChild
