One of the major users of space in /var is the systemd journal files.
Here's the sizes of /var subdirectories on my laptop:-
root@t470# du -sm *
5 backups
176 cache
1 ipp-usb
311 lib
1 local
0 lock
2586 log
1 mail
4 opt
0 run
8 spool
1 tmp
7 www
/var/log (which is where systemd puts its log files) is by far the
biggest. If you then go and look in /var/log you will almost certainly
find that nearly all the spoace sonsumed is in /var/log/journal, the
systemd journal files.
THe systemd journal file defaults for length of time they are kept and
maximum size etc. are OK[ish] for systems with lots of disk space but
are far too large for smaller systems.
On systems I have with limited space I modify /etc/systemd/journald.conf
to reduce disk usage, I set the SystemMaxUse and MaxRetentionSec
parameters.
