uWSGI Stats服务器

除了 SNMP ,uWSGI还支持一个Stats服务器机制,它将uWSGI状态作为一个JSON对象导出到一个socket。

只需使用 stats 选项,后面跟着一个有效的socket地址。如果你想通过HTTP提供stats,那么还需要添加 stats-http 选项。

  1. --stats 127.0.0.1:1717
  2. --stats /tmp/statsock
  3. --stats :5050
  4. --stats @foobar
  5. # Any of the above socket types can also return stats using HTTP
  6. --stats 127.0.0.1:1717 --stats-http

如果客户端连接到一个指定的socket,那么在连接结束之前,它将获得一个包含uWSGI内部统计数据的JSON对象。

  1. uwsgi --socket :3031 --stats :1717 --module welcome --master --processes 8

然后

  1. nc 127.0.0.1 1717
  2. # or for convenience...
  3. uwsgi --connect-and-read 127.0.0.1:1717

将返回像这样的东东:

uwsgitop

uwsgitop 是一个类似于top的命令,它使用stats服务器。可以在PyPI找到,因此使用 easy_install 或者 pip 来安装它 (自然而然地,包名是 uwsgitop)。

可以在Github找到其源码。https://github.com/unbit/uwsgitop
