Context:

I have an elastic beanstalk application with linux ec2, when i enter via SSH and I check the configuration i noticed it is not working as expected (from the configuration files)

My logfiles are being rotated every hour no matter the file size

This is my configuration file

/var/log/nodejs/nodejs.log 
size 10M
missingok
notifempty
rotate 5
sharedscripts
compress
copytruncate
dateext
dateformat -%s
olddir /var/log/nodejs/rotated
postrotate
 /etc/init.d/rsyslog restart > /dev/null
endscript

And my logs are very small, but anyway they are rotated every hour without exception.

The output when running logrotate in debug mode is as follows

sudo logrotate -d --force /etc/logrotate.elasticbeanstalk.hourly/logrotate.elasticbeanstalk.nodejs.conf

After I realized that it force the rotation, so i did another check without --force option

sudo logrotate -d /etc/logrotate.elasticbeanstalk.hourly/logrotate.elasticbeanstalk.nodejs.conf

and i received this information

olddir is /var/log/nodejs/rotated, empty log files are not rotated, old logs are removed
considering log /var/log/nodejs/nodejs.log
 log does not need rotating
not running postrotate script, since no logs were rotated

But for some strange reason when i see the files rotated every hour the size is minimal,

drwxr-xr-x 3 nodejs root 4.0K Oct 29 19:13 ..
-rw-r--r-- 1 root root 2.4K Oct 30 01:01 nodejs.log-1540861261.gz

Solution
Finally I noticed that the elastic beanstalk application itself have an option specific for that, I guess it is an underlying configuration for sending logs to S3 or Cloudwatch, so I disabled that option and it works fine now.

The option is

Rotate logs: disabled(default)
