Zabbix监控Nginx 和PHP-FPM状态
Nginx自带监控模块ngx_http_stub_status_module提供Nginx的基本信息在编译安装Nginx时加参数 --with-http_stub_status_module
安装好以后可以通过nginx -V|grep http_stub_status_module 查看状态模块是否已安装
PHP-FPM也自带监控，通过在php-fpm.conf中设置
pm.status_path = /php-fpm_status
就可以获取URL的方式获取PHP-FPM的状态

[*] 添加nginx_status.conf
server {
listen 88 ;
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
# allow 10.4.1.125;
deny all;
}
location /php-fpm_status {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}

Active connections: 1

Reading: 0 Writing: 1 Waiting: 0
Active connections
The current number of active client connections including Waiting connections.
活跃客户端连接数，包括处于等待状态的连接数
accepts
The total number of accepted client connections.
接收到的客户端连接总数
handled
The total number of handled connections. Generally, the parameter value is the same as accepts unless some resource limits have been reached
处理请求的总数。通常情况下，这个值和accepts的值相同。除非达到了一些资源限制。例如设置worker_connections 1024；设置一个worker进程能够打开的最大并发连接数。
requests
The total number of client requests.
客户端请求总数
Reading
The current number of connections where nginx is reading the request header.
当前Nginx正在读取请求头的连接数量
Writing
The current number of connections where nginx is writing the response back to the client.
当前Nginx正在将响应写回到客户端的连接数量
Waiting
The current number of> 当前正在等待请求的闲置客户端连接数量

max children reached number of times, the process limit has been reached, when pm tries to start more children. If that value is not zero, then you may need to increase max process limit for your PHP-FPM pool. Like this, you can find other useful information to tweak your pool better way.如果这个值不为0，最好增大最大进程的限制。
slow requests 如果这个值不为0，表示有处理慢的程序

2.编写Nginx和PHP-FPM状态信息获取脚本
nginx_status.sh
#!/bin/bash
#check nginx status
#ip=$(ifconfig eth0|grep "inet addr"|sed's/^.*addr://'|awk '{print $1}')
#echo $ip
ip=127.0.0.1
port=88
#echo $ip:$port
function active(){
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|grep "Active"|awk '{print $NF}'
}
function reading() {
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|grep "Reading"|awk '{print $2}'
}
function writing() {
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|grep "Writing"|awk '{print $4}'
}
function waiting() {
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|grep "Waiting"|awk '{print $6}'
}
function accepts() {
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|awk 'NR==3{print $1}'
}
function handled() {
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|awk 'NR==3{print $2}'
}
function requests(){
/usr/bin/curl http://$ip:$port/nginx_status 2>/dev/null|awk 'NR==3{print $3}'
}
case $1 in

php-fpm_status.sh
#!/bin/bash

function idle(){
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "idle processes"|awk '{print $3}'
}
function active() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "active processes"|awk '{print $3}'|grep -v "processes"
}
function total() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "total processes"|awk '{print $3}'|grep -v "processes"
}
function mactive() {

}
function conn() {

}
function since() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "start since"|awk '{print $3}'
}
function slow() {

}
function listenqueue() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "listen queue:"|grep -v "max"|awk '{print $3}'
}
function maxlistenqueue() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "max listen queue:"|awk '{print $4}'
}
function listenqueuelen() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "listen queue len:"|awk '{print $4}'
}
function maxchildren() {
/usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "max children reached:"|awk '{print $4}'
}

3.添加zabbix的子配置文件
nginx_status_zabbix.conf
