Serverless では Lambda 関数が多く、ブラウザで Screenboard を作成するのは辛いと思うのでスクリプトを書いてみました。 Widget は 全て Graph で作成しています。

    'api_key': 'xxxxxxxxxxxxxxxxxxxxxx',
    'app_key': 'xxxxxxxxxxxxxxxxxxxxxx'

    'duration': [
        'aws.lambda.duration',
        'aws.lambda.duration.maximum',
        'aws.lambda.duration.minimum',
        'aws.lambda.duration.sum'
    ],

        'aws.lambda.errors'

        'aws.lambda.throttles'
    ]
}
