1、获取 Nginx 状态( HTTP Stub Status )/usr/local/nginx/sbin/nginx -V
2、配置 nginx.confvim /usr/local/nginx/conf/nginx.conf
location ~ /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
allow 192.168.1.14;
deny all;
}
3、编写脚本获取上面的 key 值vim /script/nginx_status.sh
#!/bin/bash
case $1 in
active)
curl -s http://127.0.0.1/nginx_status | awk '/Active/ {print $3}' ;;
accepts)
curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $1}' ;;
handled)
curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $2}' ;;
requests)
curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $3}' ;;
reading)
curl -s http://127.0.0.1/nginx_status | awk '/Reading/ {print $2}' ;;
writing)
curl -s http://127.0.0.1/nginx_status | awk '/Writing/ {print $4}' ;;
waiting)
curl -s http://127.0.0.1/nginx_status | awk '/Waiting/ {print $6}' ;;
*)
echo "Usage: $0 { active | accepts | handled | requests | reading | writing | waiting }" ;;
esac
chmod a+x /script/nginx_status.sh
4、添加自定义 key 配置文件vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/nginx_status.conf
# Nginx_status
UserParameter=nginx.active,/script/nginx_status.sh active
UserParameter=nginx.accepts,/script/nginx_status.sh accepts
UserParameter=nginx.handled,/script/nginx_status.sh handled
UserParameter=nginx.requests,/script/nginx_status.sh requests
UserParameter=nginx.reading,/script/nginx_status.sh reading
UserParameter=nginx.writing,/script/nginx_status.sh writing
UserParameter=nginx.waiting,/script/nginx_status.sh waiting
5、修改zabbix_agentd.conf
vim /usr/local/zabbix/etc/zabbix_agentd.conf
LogFile=/tmp/zabbix_agentd.log
Server=192.168.1.14
ServerActive=192.168.1.14
Hostname=Zabbix server
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/
EnableRemoteCommands=1
UnsafeUserParameters=1
6、Zabbix 服务端测试能否拿到 Key/usr/local/zabbix/bin/zabbix_get -s 192.168.1.12 -k nginx.active
Nginx 监控项解释
Active connections: 1
server accepts handled requests
1 1 1
Reading: 0 Writing: 1 Waiting: 0
## Active connections: 对后端发起的活动连接数
## Server accepts handled requests: Nginx 总共处理了 1 个连接，成功创建了 1 次握手(没有失败次数)，总共处理了 1 个请求
## Reading: Nginx 读取到客户端的 Header 信息数
## Writing: Nginx 返回给客户端的 Header 信息数
## Waiting: 开启 keep-alive 的情况下，这个值等于 active - ( reading + writing ), 意思是 Nginx 已经处理完成，正在等待下一次请求指令的驻留连接
## 在访问效率很高，请求很快被处理完毕的情况下，Waiting 数比较多是正常的。如果 reading + writing 数较多，则说明并发访问量很大，正在处理过程中
