如何在python中禁用来自lambda的默认日志消息 [英] How to disable default log messages from lambda in python

问题描述

我有一个用python编写的AWS Lambda函数，我只需要在CloudWatch Logs中记录的消息。
我已经尝试了watch望塔中给出的示例，但是仍然无法正常工作。

I have an AWS Lambda function written in python, and i need only the messages I log in CloudWatch Logs. I have tried the example given in watchtower, but it still didn't work.

START RequestId: d0ba05dc-8506-11e8-82ab-afe2adba36e5 Version: $LATEST
(randomiser) Hello from Lambda
END RequestId: d0ba05dc-8506-11e8-82ab-afe2adba36e5
REPORT RequestId: d0ba05dc-8506-11e8-82ab-afe2adba36e5
Duration: 0.44 ms Billed Duration: 100 ms Memory Size: 128 MB   Max Memory Used: 21 MB*

从上面我只需要Lambda的（randomiser）Hello 即可登录CloudWatch，而无需 START ， END 和 REPORT 行。

From the above I only need (randomiser) Hello from Lambda to be logged in CloudWatch, without the START, END and REPORT lines.

推荐答案

如果启用了日志，则总是会获取默认日志。您无法禁用它们。

If you have logs enabled, you are always going to get the default logs. No way you can disable them.

但是，在某些情况下，您可能希望某个特定的Lambda函数完全不发送日志。您可以通过专门为该Lambda函数创建一个新角色来解决此问题，并且在那里没有日志记录权限。

However there might be cases where you want one specific Lambda function to not send logs at all. You can solve this by creating a new role specifically for that Lambda function, and not have the logging permission there.

FWIW，如果需要在日志记录和无日志记录之间切换通常，您可以具有以下策略文件。

FWIW, if you need to toggle between logging and no logging frequently, you can have a policy file as the following.


{
版本： 2012-10 -17，
声明：[
{
效果： Deny，
操作：[
logs：CreateLogGroup，
logs：CreateLogStream，
logs：PutLogEvents
]，
资源：[
arn：aws：logs：*：*：*
]
}
]
}


并更改需要记录时，将拒绝更改为允许。

and change the "Deny" to "Allow" when you require logging.
