uwsgi基础——服务状态

原文： http://projects.unbit.it/uwsgi/wiki/StatsServer

uWSGI 统计服务 (1.0-dev)

除了SNMP之外，uwsgi可以实时导出它的统计到一个socket上。

简单的使用--stats 加有效的socket：

--stats 127.0.0.1:1717
--stats /tmp/statsock
--stats :5050
--stats @foobar

如果一个客户端连接上指定的socket，他会得到json数据包含内部统计信息。

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

then

nc 127.0.0.1 1717

会得到类似下面的：
