清除已不存在的lambda的cloudwatch 日志组

1、脚本一

#coding:utf-8
import boto3

lambda_client = boto3.client('lambda',region_name = 'us-west-2')
log_client = boto3.client('logs',region_name = 'us-west-2')
log_list = log_client.describe_log_groups(logGroupNamePrefix='/aws/lambda/')
lambda_list = lambda_client.list_functions()

lambdalist = []
for l in lambda_list['Functions']:
    lambdalist.append(l['FunctionName'])

print(lambdalist)
for l in log_list['logGroups']:if l['logGroupName'].replace('/aws/lambda/','') not in lambdalist:
        print(l['logGroupName'].replace('/aws/lambda/',''))
        response = log_client.delete_log_group(logGroupName=l['logGroupName'])
        print("删除结果：",response)

2、脚本二

#coding:utf-8
import boto3

lambda_client = boto3.client('lambda',region_name = 'us-west-2')
log_client = boto3.client('logs',region_name = 'us-west-2')
log_list = log_client.describe_log_groups()
lambda_list = lambda_client.list_functions()

lambdalist = []
for l in lambda_list['Functions']:
    lambdalist.append(l['FunctionName'])

print(lambdalist)
for l in log_list['logGroups']:
    if l['logGroupName'].startswith('/aws/lambda/'):
        if l['logGroupName'].replace('/aws/lambda/','') not in lambdalist:
            print(l['logGroupName'].replace('/aws/lambda/',''))
            response = log_client.delete_log_group(logGroupName=l['logGroupName'])
            print("删除结果：",response)

注释： 罗列日志组时一页最多可以显示50条，虽然一次删不干净，多执行两次就OK了。
