nginx status详解

active connections – 活跃的连接数量

server accepts handled requests — 总共处理了11989个连接 , 成功创建11989次握手, 总共处理了11991个请求

reading — 读取客户端的连接数.

writing — 响应数据到客户端的数量

waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.

--------------------------------------------

首先在agent端的nginx.conf中添加下面内容

# vim /usr/local/nginx/conf/nginx.conf

server {

           listen 80;

           server_name localhost;

           location /nginxstatus{

                                          stub_status on;

                                          access_log off;

                                          allow 127.0.0.1;

                                          allow 192.168.1.0/24;                ----->zabbix server端的IP地址

                                          deny all;

                                          }

}

 

然后写监控nginx状态的脚本

# vim /usr/local/zabbix/scripts/nginx.status.sh

#!/bin/bash

function active {

                       curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk '/Active/ {print $3}'

}

function reading {

                         curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk '/Reading/ {print $2}'

}

function writing {

                        curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk '/Writing/ {print $4}'

}

function waiting {

                       curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk '/Waiting/ {print $6}'

}

function accepts {

                         curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk NR==3|awk '{print $1}'

}

function handled {

                         curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk NR==3|awk '{print $2}'

}

function requests {

                         curl "http://127.0.0.1/nginxstatus" 2>/dev/null|awk NR==3|awk '{print $3}'

}

case "$1" in

       active

       ;;

*)

echo "Usage: $0 {nginx_site_dicovery}"

      echo "Usage: $0 {active [host]|reading [host]|writing [host]|waiting [host]|accepts [host]|handled [host]|requests [host]}"

      esac

修改权限

# chmod 755 /usr/local/zabbix/scripts/mysql.status.sh

测试脚本

# /usr/local/zabbix/scripts/nginx.status.sh active

1

 

修改zabbix agent的配置文件

# vim /usr/local/zabbix/etc/zabbix_agentd.conf

Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/      --->配置文件key的路径

UnsafeUserParameters=1                                            ---》允许特殊字符

 

增加nginx key的配置文件

# vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/nginx.status.conf

UserParameter=nginx.accepts,/usr/local/zabbix/scripts/nginx.status.sh accepts

UserParameter=nginx.handled,/usr/local/zabbix/scripts/nginx.status.sh handled

UserParameter=nginx.requests,/usr/local/zabbix/scripts/nginx.status.sh requests

UserParameter=nginx.active,/usr/local/zabbix/scripts/nginx.status.sh active

UserParameter=nginx.reading,/usr/local/zabbix/scripts/nginx.status.sh reading

UserParameter=nginx.writing,/usr/local/zabbix/scripts/nginx.status.sh writing

UserParameter=nginx.waiting,/usr/local/zabbix/scripts/nginx.status.sh waiting

然后agent端测试

# /usr/local/zabbix/sbin/zabbix_agentd -t nginx.active

nginx.active [t|1]

重启agent服务

service zabbix_agentd restart

在zabbix添加nginx模板key查看即可
