概述
新上线一个nginx+php-fpm的项目，最近时长收到一些平均响应时间的告警，为了方便查看php-fpm进程都在处理啥请求，以及处理时长，就有了下面这个脚本
获取指标
| 指标 | 说明 |
|---|---|
| pid | 进程ID |
| requests | 进程已处理的请求数 |
| duration | 请求时长（秒） |
| method | 请求方法 |
| length | POST内容长度 |
| uri | 请求URI(最多取60个字符串) |
get_php-fpm_running.py
$ cat get_php-fpm_running.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-

获取PHP-FPM正在运行并响应时间超过默认10s的进程。

headers = ['pid', 'requests', 'duration', 'method', 'length', 'uri']

l.append(process_info)

实时显示可以通过watch进行封装
$ watch -n5 ./get_php-fpm_running.py 3
