Zabbix 之监控Nginx状态信息
nginx需要支持 http_stub_status_module 编译的时候需要使用--with-http_stub_status_module
yum默认支持此选项
1. 配置nginx stuats
源码: vim nginx.conf
yum: vim /etc/nginx/conf.d/default.conf
#and add the following to your server block
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
allow 172.16.7.70; #Put your servers IPaddress instead of 172.16.7.70
deny all;
}
# 检测配置文件
nginx -t
# 重新加载配置文件
nginx -s reload
2.查看Nginx状态信息
curl localhost/nginx_status
注解：
Active connections: 1 当前活动的连接数
server accepts handled requests
3721 3721 3714
3721 从启动到现在一共处理的连接数
3721 从启动到现在成功创建的握手的次数
3714 总共处理的请求数(requests)
请求的丢失数＝（握手－连接）
connection 连接数，tcp连接
request http请求，GET/POST/DELETE
Reading: 0 Writing: 1 Waiting: 0
Reading: 0 读取客户端Header的信息数 请求头
Writing: 1 返回给客户端的header的信息数 响应头
Waiting: 0 等待的请求数
3. zabbix客户端配置
#创建检测脚本
mkdir /usr/local/zabbix/scripts
vi /usr/local/zabbix/scripts/nginx_status.sh
#!/bin/bash
# Script to fetch nginx statuses for tribily monitoring systems
# Author: krish@toonheart.com
# License: GPLv2
# Set Variables
#BKUP_DATE=`/bin/date +%Y%m%d`
#LOG="/etc/zabbix/nginx_status.log"
HOST=`/sbin/ifconfig eth0 | sed -n ‘/inet /{s/.*addr://;s/ .*//;p}‘`
PORT="80"
# Functions to return nginx stats
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}‘
}
# Run the requested function
$1
# 对脚本赋予执行权限
chmod +x /usr/local/zabbix/scripts/nginx_status.sh
# 修改agent 配置文件
vim /usr/local/zabbix/etc/zabbix_agentd.conf
#开启自定义KEY功能
UnsafeUserParameters=1
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.connections.active,/usr/local/zabbix/scripts/nginx_status.sh active
UserParameter=nginx.connections.reading,/usr/local/zabbix/scripts/nginx_status.sh reading
UserParameter=nginx.connections.writing,/usr/local/zabbix/scripts/nginx_status.sh writing
UserParameter=nginx.connections.waiting,/usr/local/zabbix/scripts/nginx_status.sh waiting
#重启zabbix_agentd
/etc/init.d/zabbix_agentd restart
4.服务端测试
# /usr/local/zabbix/bin/zabbix_get -s 172.16.99.25 -knginx.accepts
12877
# 有信息返回说明配置正常
# 有图有真相
#模板

FAQ : 若果是无返回信息则说明agent端配置错误这是查看zabbix_agentd.log 的输出日志，排查错误
