How to use date and time as part of filename on Logrotate?

I need to use time and date as an extension of rotated logs. Right now I'm using dateext, but the problem is that I can't achieve rotation more than once on same date/day and I have to do rotation on hourly basis

Here is the logorotate configuration that I created:

/someDirectory/logs/*.log {
    nocompress
    notifempty
    copytruncate
    size 100M
    dateext
    olddir someDirectory/logs/archived
    rotate 10
}

What am I missing?

Solution

  • You can use postrotate script like:

       someDirectory/logs/*.log /someDirectory/logs/*.log {
   nocompress
   notifempty
   copytruncate
   size 100M
   dateext
   olddir someDirectory/logs/archived
   rotate 10
   sharedscripts
   postrotate
        day=$(date +%Y%m%d)
        daytime=$(date +%Y%m%d-%H:%M:%S)
        mv somelog-$day /var/log/somelog-$daytime
   endscript
  }
