利用php-fpm-exporter对php-fpm进行监控

• 1、php-fpm开启status接口
• 2、nginx代理php-fpm接口
• 3、使用php-fpm-exporter暴露指标给Prometheus
• 4、granfna展示

一、 php-fpm 开启status接口

需要提前安装好php,和nginx 环境

• 1、 找到php配置文件，修改配置,开启status vim /usr/local/php/etc/php-fpm.conf

  ... pm.status_path = /status ping.path = /ping ...

• 2、 配置nginx

  server { listen 9010; allow 127.0.0.1; deny all;

        location ~ ^/(status|ping)$ {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
  

  }

• 3、检查status是否可以访问

  [root@Prometheus conf]# curl http://127.0.0.1:9010/status pool: www process manager: dynamic start time: 23/Feb/2020:11:54:50 +0800 start since: 10626 accepted conn: 1 listen queue: 0 max listen queue: 0 listen queue len: 128 idle processes: 14 active processes: 1 total processes: 15 max active processes: 1 max children reached: 0 slow requests: 0

二、 使用php-fpm-exporter暴露指标

• 1、下载php-fpm-exporter,并启动

  wget https://github.com/bakins/php-fpm-exporter/releases/download/v0.6.1/php-fpm-exporter.linux.amd64 mkdir -p /usr/local/exporter/php-fpm/ mv php-fpm-exporter.linux.amd64 /usr/local/exporter/php-fpm/php-fpm-exporter nohup /usr/local/exporter/php-fpm/php-fpm-exporter --addr 0.0.0.0:9190 --endpoint http://127.0.0.1:9010/status &

• 2、检查metrics是否可以访问

  [root@Prometheus php-fpm]# curl 127.0.0.1:9190/metrics

  TYPE phpfpm_accepted_connections_total counter

  phpfpm_accepted_connections_total 4

  TYPE phpfpm_slow_requests_total counter

  phpfpm_slow_requests_total 0

  HELP phpfpm_up able to contact php-fpm

三、配置promethus，采集php-fpm的数据

vim /usr/local/promethus/promethus.yml

  - job_name: 'php-fpm'
    static_configs:
    - targets:
      - 114.67.116.119:9190

四、配置granfna进行数据展示
