Amazon Polly: Statistics of audio files

For that you will need to access the Server access logging of the S3 bucket where your are storing your files. For details, see Enabling Amazon S3 server access logging.

This feature provides detailed records for the requests that are made to an Amazon S3 bucket, so you will be able to see how many times an object in that bucket is accessed.

You can also use Amazon Athena to analyse this logs. Analyse my Amazon S3 server access logs using Athena.

Thanks a lot for the reply igsalvar. Following your instructions, I activated Server access logging of the S3 bucket. With Athena, I created a database and table following the directions. Now I need help to create a query that allows me to obtain the number of views of .mp3 files. Can you help me? Thanks again

You can use this query to visualize all the operations done in a specific object key:

SELECT count(*) as AccessNumber
FROM s3_accesslogs_db.mybucket_logs
WHERE key = 'keyprefix/keyobject.file' 
AND operation = 'REST.GET.OBJECT' ;

Just change the second line ('s3_accesslogs_db.mybucket_logs') for your database name and the third line ('keyprefix/keyobject.file') for the key of your object.

You could also include additional conditional lines to that query to filter by IP or by a specific time frame. Example:

WHERE remoteIP='1.2.3.4' AND 
parse_datetime(requestdatetime,'dd/MMM/yyyy:HH:mm:ss Z')
BETWEEN parse_datetime('2021-07-01','yyyy-MM-dd')
AND parse_datetime('2021-08-01','yyyy-MM-dd');
