用zabbix监控nginx

zabbix监控nginx

实验环境

	服务端	客户端
主机名	R1	R2
IP	192.168.147.44	192.168.147.66
安装	zabbix_server zabbix_agent	zabbix_agent nginx

在服务段部署zabbix

部署zabbix

在客户端部署nginx

部署nginx

配置nginx

[root@R2 ~]# vim /usr/local/nginx/conf/nginx.conf
        location /nginx_status {
            stub_status on; 
            allow 127.0.0.1;
            allow 192.168.147.1;
            deny all;
        }
[root@R2 ~]# nginx -s reload

编写脚本

[root@R2 ~]# mkdir /scripts
[root@R2 ~]# vim /scripts/check_nginx.sh
#!/bin/bash
#Script to fetch nginx statuses for monitoring systems
 
HOST="127.0.0.1"
PORT="80"
 
function ping {
    /sbin/pidof nginx | wc -l
}
 
function active {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
$1
[root@R2 ~]# chmod +x /scripts/check_nginx.sh

zabbix-agent配置文件开启自定义功能

[root@R2 ~]# vim /usr/local/etc/zabbix_agentd.conf

UnsafeUserParameters=1   #取消注释并改为1
在最后的空白处添加
UserParameter=check_nginx[*],/bin/bash /scripts/check_nginx.sh $1

[root@R2 ~]# pkill zabbix
[root@R2 ~]# zabbix_agentd 

测试server端是否可以收到数据

[root@C1 etc]# zabbix_get -s 192.168.147.66 -p 10050 -k check_nginx[accepts]

[root@C1 etc]# zabbix_get -s 192.168.147.66 -k check_nginx[active]
