过滤CloudWatch Logs以提取实例ID [英] Filter CloudWatch Logs to extract Instance ID

问题描述

我有一个AWS Lambda函数，当实例终止时将调用该函数，并且该消息存储在Amazon CloudWatch Logs中。

I have an AWS Lambda function that is invoked when an instance gets terminated and this the message is stored in Amazon CloudWatch Logs.

我想提取和过滤这些记录消息以获取特定的ID。如何提取日志并使用Python对其进行过滤？

I want to extract and filter these log messages to get a particular ID. How can I extract the logs and filter it using Python?

推荐答案

最简单的方法可能是在中创建规则触发AWS Lambda函数的Amazon CloudWatch Events 。该功能自动传递与终止实例有关的信息。您可以用Python编写Lambda函数。

The easiest method might be to create a rule in Amazon CloudWatch Events that triggers an AWS Lambda function. The function automatically passes information relating to the instance that was terminated. You can write the Lambda function in Python.

这样，只要实例终止，您的函数就会自动触发，而不必浏览日志。

This way, your function is automatically triggered whenever an instance is terminated, rather than having to look through logs.
