Zabbix监控Nginx

Posted 2020-11-21 杨灏

使用nginx -V可以查看nginx是否将模块·http_stub_status_module`编译进包中：

启用Nginx status模块

location /nginx_status {
     stub_status on;
     access_log off;
     allow 127.0.0.1;
     allow 192.168.55.36/24;
     deny all;
}

然后使用浏览器或者curl指令查看nginx status:

curl http://127.0.0.1/ngx_status

Active connections: 11921
server accepts handled requests
 11989 11989 11991
Reading: 0 Writing: 7 Waiting: 42

编写nginx脚本

#!/bin/bash
#=========================>
HOST="127.0.0.1"
PORT="80"

# 检测nginx进程是否存在
function ping {
    /sbin/pidof nginx | wc -l 
}
# 检测nginx性能
function active {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep ‘Active‘ | awk ‘{print $NF}‘
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep ‘Reading‘ | awk ‘{print $2}‘
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep ‘Writing‘ | awk ‘{print $4}‘
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep ‘Waiting‘ | awk ‘{print $6}‘
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk ‘{print $1}‘
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk ‘{print $2}‘
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk ‘{print $3}‘
}

zabbix客户端配置

将自定义的UserParameter加入配置文件，然后重启agentd，如下：

UserParameter=nginx.status[*],/usr/local/zabbix-3.0.0/scripts/ngx-status.sh $1

服务端测试通过zabbix_get工具

zabbix_get -s 192.168.55.40 -k ‘nginx.status[accepts]‘

 

剩下的便是管理页面上的操作了
