Zabbix监控nginx性能
一. nginx status信息
# curl http://127.0.0.1/ngx_status
Active connections: 11921
server accepts handled requests
11989 11989 11991
Reading: 0 Writing: 7 Waiting: 42
Active connections: 11921
server accepts handled requests
11989 11989 11991
Reading: 0 Writing: 7 Waiting: 42
首先nginx需要配置ngx_status
1. 启用nginx status配置
在默认主机里面加上location或者你希望能访问到的主机里面。
server {
listen *:80 default_server;
server_name _;
location /ngx_status {
stub_status on;
access_log off;
#allow 127.0.0.1;
#deny all;
}
listen *:80 default_server;
server_name _;
location /ngx_status {
stub_status on;
access_log off;
#allow 127.0.0.1;
#deny all;
}
2. 重启nginx
请依照你的环境重启你的nginx
# service nginx restart
3. 打开status页面
# curl http://127.0.0.1/ngx_status
Active connections: 11921
server accepts handled requests
11989 11989 11991
Reading: 0 Writing: 7 Waiting: 42
Active connections: 11921
server accepts handled requests
11989 11989 11991
Reading: 0 Writing: 7 Waiting: 42
4. 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.

二 配置客户端
1. 编写客户端脚本ngx_status.sh
vim /etc/zabbix/shell/ngx_status.sh
#!/bin/bash

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

function requests {
/usr/bin/curl “http://$HOST:$PORT/ngx_status/” 2>/dev/null| awk NR==3 | awk ‘{print $3}’
}
# 执行function

2. zabbix客户端配置
将自定义的UserParameter加入配置文件，然后重启agentd，如下：
#cat /etc/zabbix/zabbix_agentd.conf | grep nginx
UserParameter=nginx.status[*],/etc/zabbix/shell/ngx_status.sh $1
UserParameter=nginx.status[*],/etc/zabbix/shell/ngx_status.sh $1
重启 zabbix-agent 使配置生效
service zabbix-agent restart
3. zabbix_get获取数据 yum install zabbix-get
zabbix_get -s 127.0.0.1 -k ‘nginx.status[accepts]’
zabbix_get -s 127.0.0.1 -k ‘nginx.status[ping]’
在zabbix server服务器上执行如上命令, 127.0.0.1为本机agentd机器 可以是host 其他agent服务器
4. zabbix web端配置
导入 Template App NGINX 模板
导入 Template App NGINX 模板 该模板添加了Nginx 是否running 的触发器
