Zabbix监控Nginx 和PHP-FPM状态

Nginx自带监控模块ngx_http_stub_status_module提供Nginx的基本信息

在编译安装Nginx时加参数 --with-http_stub_status_module 

安装好以后可以通过nginx -V|grep http_stub_status_module 查看状态模块是否已安装

PHP-FPM也自带监控，通过在php-fpm.conf中设置

pm.status_path = /php-fpm_status

就可以获取URL的方式获取PHP-FPM的状态

1. 添加nginx_status.conf
   

server {

           listen       80 ;

           location /nginx_status {          
            stub_status on;
            access_log off;
            allow 127.0.0.1;
#            allow 10.4.1.125;
            deny all;
                                  }       
           
           location /php-fpm_status {
             fastcgi_pass 127.0.0.1:9000;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
                                     }
         }

$ curl  127.0.0.1/nginx_status
Active connections: 1 
server accepts handled requests
 788163 788163 788163 
Reading: 0 Writing: 1 Waiting: 0

Active connections   

          The current number of active client connections including Waiting connections.

          活跃客户端连接数，包括处于等待状态的连接数

accepts

          The total number of accepted client connections.

          接收到的客户端连接总数

handled

        The total number of handled connections. Generally, the parameter value is the same as accepts unless some resource limits have been reached 

        处理请求的总数。通常情况下，这个值和accepts的值相同。除非达到了一些资源限制。例如设置worker_connections 1024；  设置一个worker进程能够打开的最大并发连接数。

requests

       The total number of client requests.

       客户端请求总数

Reading

       The current number of connections where nginx is reading the request header.

       当前Nginx正在读取请求头的连接数量

Writing

       The current number of connections where nginx is writing the response back to the client.

       当前Nginx正在将响应写回到客户端的连接数量

Waiting

       The current number of idle client connections waiting for a request.

       当前正在等待请求的闲置客户端连接数量

$ curl  127.0.0.1/php-fpm_status

pool                        pool名称

process manager             static or dynamic

start time                  启动时间

start since                 启动了多长时间，以秒为单位

accepted conn               pool接收到的请求数量

idle processes              空闲进程数量

listen queue               the number of request in the queue of pending connections. If this number is non-zero, then you better increase number of process FPM can spawn.
