Apache 虚拟主机每秒请求数总计监视器

Knowledge Base article:

摘要

Apache 虚拟主机的每秒请求量较高。Apache HTTP 服务器性能可能会受到负面影响。

每秒请求数是虚拟主机每秒处理的 HTTP 请求量。Apache 虚拟主机使用子进程处理传入 HTTP 请求。

此监视器阈值是按照轮询过程中返回给代理的平均值分析的，其中“样本数”参数控制平均值计算中所包含的样本数。

原因

不正常状态表示每秒请求量当前较高。这可能是由于虚拟主机上的流量增加所引起的。默认阈值可能不适合于每个 Apache HTTP 服务器实例。

解决方法

要解决虚拟主机上每秒请求数较高的情况，请选择以下一个或多个选项：

配置

默认配置

参数

默认值

阈值

100

样本数

替代可用于更改以上为所有实例或为特定实例或组定义的参数值
