1nginx状态模块
nginx内置了一个状态页，用于了解nginx状态，并可以配置监控。
server {
listen *:80 default_server;
server_name _;
location /ngx_status
{
stub_status on;
access_log off;
#allow 127.0.0.1;
#deny all;
}
}
curl 127.0.0.1/ngx_status Active connections: 91 server accepts handled requests 32979 32979 55594 Reading: 0 Writing: 29 Waiting: 62
2 配置监控
[root@iZbp1ezumclop9223l31okZ zabbix]# cat scripts/nginx_status.sh
#!/bin/sh
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}\'
}
# 执行function
$1
#建立数据采集脚本
[root@iZbp1ezumclop9223l31okZ zabbix]# cat etc/zabbix_agentd.conf.d/nginx.conf UserParameter=nginx.status[*],/app/zabbix/scripts/nginx_status.sh $1 #创建自定义监控
zabbix_get -s 127.0.0.1 -k \'nginx.status[accept]\' #重启agent后，在server端测试配置
3 数据含义
导入xml模板后，可以显示监控。
Active connections：目前的连接数（ESTABLISHED）
Writing：处于响应请求的连接数
Waiting：开启keep-alive后等候下一次请求指令的驻留连接.
xml模板：
<?xml version="1.0" encoding="UTF-8"?>
