在调试程序中，通过日志分期来排查 BUG 是一个重要手段，它可以说是程序调试的利器。
关于日志管理
随着应用组件变多，那么各 coder 对输出日志五花八门，有写入 stdout，有写 stderr, 有写到 syslog，也有写到 xxx.log 的。那么这将导致平台应用日志分布在各个地方，无法统一管理。
为什么使用 Sentry
Sentry 是一个集中式日志管理系统。它具备以下优点：
- 多项目，多用户
- 界面友好
- 可以配置异常出发规则，例如发送邮件
- 支持主流语言接口

实例
PHP
使用浏览器访问 sentry，并创建一个项目
参考 PHP 使用指令 http://10.0.0.180/sentry/45183e54fa36/settings/install/php/
<?php
require_once “vendor/autoload.php”;
$client = new Raven_Client(‘http://5d68caa5e36c4eaa8f7c0601a521fab6:b5917e01d45f4656ab2d943264b90377@10.0.0.180/3’);
$error_handler = new Raven_ErrorHandler($client);
$error_handler->registerExceptionHandler();
$error_handler->registerErrorHandler();
$error_handler->registerShutdownFunction();
$client->captureMessage(“ 这里发生了一个错误 ”);
$i = 1 / 0;
?>
Python
pip install raven
from raven import Client
client = Client(‘http://f1ba62aa87cb4fc1a36d9e4f96017e99:96f5feef13dc4d45825e73548cd5b784@10.0.0.180/4’)
try:
1 / 0
except ZeroDivisionError:
client.captureException()
