What is size in logrotate?

size size Log files are rotated only if they grow bigger then size bytes. If size is followed by k, the size is assumed to be in kilo- bytes. If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, size 100k, size 100M and size 100G are all valid.

How often does logrotate check size?

Normally, logrotate is run as a daily cron job. It will not modify a log more than once in one day unless the criterion for that log is based on the log’s size and logrotate is being run more than once each day, or unless the -f or –force option is used. Any number of config files may be given on the command line.
