/var file system
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.
Attention: If applications on your system use the /var file system extensively, routinely run the skulker command or 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 monitor are:
|/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.
|/var/adm||Contains system logging and accounting files|
|/var/news||Contains system news|
|/var/preserve||Contains preserved data from interrupted edit sessions; similar to the /usr/preserve directory in previous releases|
|/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/tmp.|
