Attention: The /var file system tends to grow because it contains subdirectories and data files that are used by busy applications such as accounting, mail, and the print spooler. If applications on your system use the /var file system extensively, increase the file system size beyond the 4MB /var default.
Specific /var files that warrant periodic monitoring are /var/adm/wtmp and /var/adm/ras/errlog.
Other /var files to
|/var/adm/ras/trcfile||If the trace facility is turned on|
|/var/tmp/snmpd.log||If the snmpd command is running on your system.|
The /var directory diagram shows some of the directories in the /var file system.
Figure 7-4. /var Directory. . This diagram shows the major subdirectories of the /var directory, including /adm, /news, /preserve, /spool, /tmp, and /lpp.
|/var/adm||Contains system logging and accounting files|

|/var/spool||Contains files being processed by programs such as electronic mail; similar to the /usr/spool directory in previous releases|
|/var/tmp||Contains temporary files; similar to the /usr/tmp directory in previous releases. The /usr/tmp directory is now a symbolic link to /var/temp.|
