Details about the issue

I have an s3 mount to the /folder in my CentOS7.6 machine. I have enabled the debug level as INFO. I have observed that 1GB file writes large number of log lines in /var/log/messages and i am unable to understand the file get uploaded or not.
_What i need exactly is, when a file get uploaded from s3 mount folder to s3-bucket it should log in /var/log/messages be like "INFO: File /data/flow.json uploaded to BUCKET_NAME" Is there a way to get it, or do i need to do configure any in s3-fuse?
My team wants to read that line and keeps the history of file upload stats
Any help on this, please?

My fs tab entry:
s3fs#my-s3-bucket /my-folder fuse _netdev,uid=owt,gid=owt,allow_other,use_cache=/tmp,mp_umask=022,dbglevel=info,retries=5, 0 0

s3fs sends objects to S3 during fsync and close. If you application issues these calls, then it will be uploaded to S3. There is currently no asynchronous flushing.
