Zabbix监控Nginx

服务器系统	角色	IP
CentOS 7.4 x86_64	Zabbix-Server	172.16.1.71
CentOS 7.4 x86_64	Zabbix-Agent	172.16.1.7

2. 在nginx.cong的Server标签下加入下面内容
[root@web01 conf.d]# cat status.conf
server {
listen 80;
server_name _;

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

3.本地访问Nginx Status

[root@web01 conf.d]# curl http://127.0.0.1/nginx_status
Active connections: 1
server accepts handled requests
255 255 252
Reading: 0 Writing: 1 Waiting: 0

4.编写Nginx的shell脚本

[root@web01 ~]#  mkdir -p /etc/zabbix/scripts

[root@web01 ~]# vim /etc/zabbix/scripts/nginx_status.sh

#!/bin/bash

NGINX_COMMAND=$1
NGINX_PORT=80

nginx_active(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Active/ {print $NF}'
}

nginx_reading(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Reading/ {print $2}'
}

nginx_writing(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Writing/ {print $4}'
}

nginx_waiting(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk '/Waiting/ {print $6}'
}

nginx_accepts(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $1}'
}

nginx_handled(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $2}'
}

nginx_requests(){
/usr/bin/curl -s "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" |awk 'NR==3 {print $3}'
}

case $NGINX_COMMAND in
active|ACTIVE)
nginx_active;
;;
reading)
nginx_reading;
;;
writing)
nginx_writing;
;;
waiting)
nginx_waiting;
;;
accepts)
nginx_accepts;
;;
handled)
nginx_handled;
;;
requests)
nginx_requests;
;;
*)
echo $"USAGE:$0 {active|reading|writing|waiting|accepts|handled|requests}"
esac

[root@web01 ~]# chmod +x  /etc/zabbix/zabbix_agentd.d/scripts/nginx_status.sh

6.监控项 nginx_status.conf的配置文件如下：

cat /etc/zabbix/zabbix_agentd.d/nginx.conf
UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/scripts/nginx_status.sh "$1"

7.重启zabbix-agent

systemctl restart zabbix-agent.service

8.使用zabbix-get获取值

[root@zabbix ~]# zabbix_get -s 172.16.1.7 -k nginx_status[handled]
