python - 如何使用boto3列出Cloudwatch中的所有日志组

Question

如何使用 Boto3 列出 Cloudwatch 中的所有日志组。当我尝试以下语法时。我收到错误。

client = boto3.client('logs')

response = client.describe_log_groups(limit=51)

validation error detected: Value '51' at 'limit' failed to satisfyconstraint: Member must have value less than or equal to 50

基于documentation我们可以超过 50

limit (integer) -- The maximum number of items returned. If you don'tspecify a value, the default is up to 50 items.

Answer 1

如有疑问，请始终访问 API documentation ，其内容如下:

Valid Range: Minimum value of 1. Maximum value of 50.

要解决您的问题，您需要使用paginator :

paginator = logs_client.get_paginator('describe_log_groups')
for page in paginator.paginate():
    for group in page['logGroups']:
        print(group)
