Boto3 CloudFront Object 使用次数

Question

Looking to count the number of times all of the objects in my CloudFront dist has been hit individually so that I can generate an excel sheet to track usage stats. I've been looking through the boto3 docs for CloudFront and I haven't been able to peg down where that information could be accessed. I see that AWS Cloudfront console generates a 'Popular Objects' report. I wasn't sure if anyone knew how to get the numbers that AWS generates for that report in boto3?

If it's not accessible through Boto3, would there be an AWS CLI command that I should use instead?

UPDATE:

Here's what I ended up using as pseudo-code, hopefully it's a starting point for someone else:

import boto3
import gzip
from datetime import datetime, date, timedelta
import shutil
from xlwt import Workbook

def analyze(timeInterval):
    """
    analyze usage data in cloudfront
    :param domain:
    :param id:
    :param password:
    :return: usage data
    """
    outputList = []
    outputDict = {}

    s3 = boto3.resource('s3', aws_access_key_id=AWS_ACCESS_KEY_ID, aws_secret_access_key=PASSWORD)
    data = s3.Bucket(AWS_STORAGE_BUCKET_NAME)
    count = 0
    currentDatetime = str(datetime.now()).split(' ')
    currentDatetime = currentDatetime[0].split('-')
    currentdatetimeYear = int(currentDatetime[0])
    currentdatetimeMonth = int(currentDatetime[1])
    currentdatetimeDay = int(currentDatetime[2])
    currentDatetime = date(year=currentdatetimeYear, month=currentdatetimeMonth, day=currentdatetimeDay)

    # create excel workbook/sheet that we'll save results to
    wb = Workbook()
    sheet1 = wb.add_sheet('Log Results By URL')
    sheet1.write(0, 1, 'File')
    sheet1.write(0, 2, 'Total Hit Count')
    sheet1.write(0, 3, 'Total Byte Count')

    for item in data.objects.all():
        count += 1
        # print(count, '\n', item)
        # print(item.key)
        datetimeRef = str(item.key).replace(CLOUDFRONT_IDENTIFIER+'.', '')
        datetimeRef = datetimeRef.split('.')
        datetimeRef = datetimeRef[0]
        datetimeRef = str(datetimeRef[:-3]).split('-')
        datetimeRefYear = int(datetimeRef[0])
        datetimeRefMonth = int(datetimeRef[1])
        datetimeRefDay = int(datetimeRef[2])
        datetimeRef = date(year=datetimeRefYear, month=datetimeRefMonth, day=datetimeRefDay)
        # print('comparing', datetimeRef - timedelta(days=1), currentDatetime)
        if timeInterval == 'daily':
            if datetimeRef > currentDatetime - timedelta(days=1):

From Configuring and Using Standard Logs (Access Logs) - Amazon CloudFront :

You can configure CloudFront to create log files that contain detailed information about every user request that CloudFront receives. These are called standard logs, also known as access logs. These standard logs are available for both web and RTMP distributions. If you enable standard logs, you can also specify the Amazon S3 bucket that you want CloudFront to save files in.

The log files can be quite large, but you can Query Amazon CloudFront Logs using Amazon Athena .
