zabbix监控nginx
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}'
}

echo "Usage: $0 {nginx_site_dicovery}"

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
