From the security hardening WP:
For the three files in /etc/logrotate.d—vmkernel, vmksummary, and vmkwarning—it is recommend
that the configuration be modified to:
Increase the size of the log file to 4096k.
Enable compression by setting the line compress instead of nocompress.
So, for /etc/logrotate.d/vmkernel - do a search for uncompress and change it to compress
do a search for size and change it to size 4096K or less
Repeat for the other files.
This sounds like information for the ESX line of VMware stuff. The hosted products don't have a "vmkernel" or associated log files. For Linux-based hosted products, you'll need to copy one of the existing logrotate files and use it as a template or create your own new one.
His post said "have anybody working logrotate configuration file for corect rotating logs in /var/log/vmware". I assumed vmware. But yeah, same thing for linux.
