Zabbix監控Nginx 和PHP-FPM狀態

Nginx自帶監控模塊ngx_http_stub_status_module提供Nginx的基本信息

在編譯安裝Nginx時加參數 --with-http_stub_status_module 

安裝好之後能夠經過nginx -V|grep http_stub_status_module 查看狀態模塊是否已安裝

PHP-FPM也自帶監控，經過在php-fpm.conf中設置

pm.status_path = /php-fpm_status

就能夠獲取URL的方式獲取PHP-FPM的狀態

1. 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;
                                     }
         }

$ curl  127.0.0.1:88/nginx_status
Active connections: 1 
server accepts handled requests
 788163 788163 788163 
Reading: 0 Writing: 1 Waiting: 0

Active connections   

          The current number of active client connections including Waiting connections.

          活躍客戶端鏈接數，包括處於等待狀態的鏈接數

accepts

          The total number of accepted client connections.

          接收到的客戶端鏈接總數

handled

        The total number of handled connections. Generally, the parameter value is the same as accepts unless some resource limits have been reached 

        處理請求的總數。一般狀況下，這個值和accepts的值相同。除非達到了一些資源限制。例如設置worker_connections 1024；  設置一個worker進程可以打開的最大併發鏈接數。

      

requests

       The total number of client requests.

       客戶端請求總數

Reading

       The current number of connections where nginx is reading the request header.

       當前Nginx正在讀取請求頭的鏈接數量

Writing

       The current number of connections where nginx is writing the response back to the client.

       當前Nginx正在將響應寫回到客戶端的鏈接數量

Waiting

       The current number of idle client connections waiting for a request.

       當前正在等待請求的閒置客戶端鏈接數量

$ curl  127.0.0.1:88/php-fpm_status
pool:                 www
process manager:      dynamic
start time:           16/Nov/2014:13:29:11 +0800

active processes:     1
total processes:      7
max active processes: 4

slow requests:        0

pool                        pool名稱

process manager             static or dynamic

start time                  啓動時間

start since                 啓動了多長時間，以秒爲單位

accepted conn               pool接收到的請求數量

listen queue               the number of request in the queue of pending connections.這個值若是不爲0，最好增長PHP-FPM的進程數量

max listen queue           the maximum number of requests in the queue of pending connections since FPM has started

listen queue len           the size of the socket queue of pending connections

idle processes             the number of idle processes

active processes           the number of active processes

total processes            the number of idle + active processes

max active processes       the maximum number of active processes since FPM has started

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.若是這個值不爲0，最好增大最大進程的限制。

slow requests               若是這個值不爲0，表示有處理慢的程序

$ curl 127.0.0.1:88/php-fpm_status?full

2.編寫Nginx和PHP-FPM狀態信息獲取腳本

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
   active)
          active
        ;;
  reading)
         reading
        ;;
  writing)
          writing
        ;;
  waiting)
          waiting
        ;;
  accepts)
          accepts
        ;;
  handled)
          handled
        ;;
  requests)
          requests
        ;;
       *)
          exit 1
        ;;
esac

       

php-fpm_status.sh

#!/bin/bash
#check php-fpm status
ip=127.0.0.1
port=88
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() {

    /usr/bin/curl http://$ip:$port/php-fpm_status 2>/dev/null|grep "max active processes"|awk '{print $4}'
                   }

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

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

function slow()   {

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

                       }

$1

                     

3.添加zabbix的子配置文件

nginx_status_zabbix.conf
