使用AWSCLI的AWS Lambda日志:如何使用AWSCLI访问Lambda日志? [英] AWS Lambda Logs using AWSCLI: How can I access Lambda logs using AWSCLI?

问题描述

我试图在ubuntu ec2实例上使用awscli使用AWS Lambda，但是我无法访问aws控制台.请注意，我没有使用无服务器或zapper，而是直接将我的main.py文件以及相关文件压缩为此处

I was trying to work with AWS Lambda using the awscli on an ubuntu ec2 instance, and I do not have access to the aws console. Note that I am not using serverless or zapper, I directly zip my main.py file along with the dependency files as mentioned here

我这样运行函数

aws lambda invoke --function-name python-test --invocation-type RequestResponse outfile.txt

输出文件中给出的错误非常模糊，在调试时无济于事，反而使我更加困惑.使用管理员的系统，我可以在控制台上运行测试时识别错误，但是如何使用awscli检查这些日志?

The errors given in the outfile are very vague and dont help in debugging, rather they confuse me more. Using the admin's system, I am able to recognize the errors when I run a test on the console, but How can I check those logs using the awscli ?

所以我尝试运行aws cloudwatch list-metrics > cloudwatch_logs.log 并在cloudwatch_logs.log文件中搜索功能名称"python-test"，我可以找到此功能的Namespace，MetricName，Dimensions，但是如何访问日志?

So I tried running aws cloudwatch list-metrics > cloudwatch_logs.log and searching the function name 'python-test' in the cloudwatch_logs.log file, I am able to find Namespace, MetricName, Dimensions for this function, but how do you access the logs ?

Any help with links to similar examples greatly appreciated !

推荐答案

首先，获取日志组名称:

aws logs describe-log-groups --query logGroups[*].logGroupName
[
    "/aws/lambda/MyFunction"
]

然后，列出该日志组的日志流:

Then, list the log streams for that log group:

aws logs describe-log-streams --log-group-name '/aws/lambda/MyFunction' --query logStreams[*].logStreamName

[
    "2018/02/07/[$LATEST]140c61ffd59442b7b8405dc91d708fdc"
]

最后，获取该流的日志事件:

aws logs get-log-events --log-group-name '/aws/lambda/MyFunction' --log-stream-name '2018/02/07/[$LATEST]140c61ffd59442b7b8405dc91d708fdc'
