    @serbaut I agree with reducing the size.
    
    However, I suggest to 
    (1) remove the delaycompress, then the files like syslog.1 or rsyslog.1 will be compressed.
    (2) keep rotate , as the compressed file are quite small (< 1MB). Keeping more compressing
files (especially cloud.log) will be helpful for troubleshooting in case we have some issues.

>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: SystemVM
>    Affects Versions: 4.8.0, 4.9.0
>            Reporter: Joakim Sernbrant
>            Priority: Critical
>
> CLOUDSTACK-6885 changed logrotate from time based to size based. This means that logs
will grow up to its size times two (due to delaycompress).
> For example:
> 50M auth.log
> 50M auth.log.1
> 10M cloud.log
> 10M cloud.log.1
> 50M cron.log
> 50M cron.log.1
> 50M messages
> 50M messages.1
> ...
> Some files will grow slowly but eventually they will get to their max size. The total
allowed log size with the current config is well beyond the size of the log partition.
> Having a full /dev/log puts the VR in a state where operations on it critically fails.
