 audomon(1M)                                                     audomon(1M)




 NAME    [Toc]    [Back]
      audomon - audit overflow monitor daemon

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/audomon [-p fss] [-t sp_freq] [-w warning] [-v] [-o
      output_tty]

 DESCRIPTION    [Toc]    [Back]
      audomon monitors the capacity of the current audit file and the file
      system on which the audit file is located, and prints out warning
      messages when either is approaching full.  It also checks the audit
      file and the file system against 2 switch points: FileSpaceSwitch
      (FSS) and AuditFileSwitch (AFS) and if either is reached, audit
      recording automatically switches to the backup audit file if it is
      available.

      The FileSpaceSwitch (FSS) is specified as a percentage of the total
      disk space available.  When the file system reaches this percentage,
      audomon looks for a backup audit file.  If it is available, recording
      is switched from the audit file to the backup file.

      The AuditFileSwitch (AFS) is specified (using audsys(1M)) by the size
      of the audit file.  When the audit file reaches the specified size,
      audomon looks for a backup audit file.  If it is available, recording
      is switched from the audit file to the backup file (see audsys(1M) for
      further information on use of this parameter).

      If either switch point is reached but no backup file is available,
      audomon issues a warning message.

      audomon is typically spawned by /sbin/init.d/auditing (as part of the
      init(1M) start-up process) when the system is booted up.  Once
      invoked, audomon monitors, periodically sleeping and ``waking up'' at
      intervals.  Note that audomon does not produce any messages when the
      audit system is disabled.

      audomon is restricted to privileged users.

    Options    [Toc]    [Back]
      -p fss         Specify the FileSpaceSwitch by a number ranging from 0
                     to 100.  When the audit file's file system has less
                     than fss percent free space remaining, audomon looks
                     for a backup file.  If available, the backup file is
                     designated as the new audit file.  If no backup file is
                     available, audomon issues a warning message.

                     The fss parameter should be a larger number than the
                     min_free parameter of the file system to ensure that
                     the switch takes place before min_free is reached.  By
                     default, fss is 20 percent.

      -t sp_freq     Specify the wake-up switch-point frequency in minutes.
                     The wake-up frequency at any other time is calculated
                     based on sp_freq and the current capacity of the audit
                     file and the file system.  The calculated wake-up
                     frequency at any time before the switch points is
                     larger than sp_freq.  As the size of the audit file or
                     the file system's free space approaches the switch
                     points, the wake-up frequency approaches sp_freq.
                     sp_freq can be any positive real number.  Default
                     sp_freq is 1 (minute).

      -w warning     Specify that warning messages be sent before the switch
                     points.  warning is an integer ranging from 0 through
                     100.  The higher the warning, the closer to the switch
                     points warning messages are issued.  For example,
                     warning = 50 causes warning messages to be sent halfway
 before the switch points are reached.  warning =
                     100 causes warning messages to be sent only after the
                     designated switch points are reached and a switch is
                     not possible due to a missing backup file.  By default,
                     warning is 90.

      -v             Make audomon more verbose.  This option causes audomon
                     to also print out the next wake-up time.

      -o output_tty  Specify the tty to which warning messages are directed.
                     By default, warning messages are sent to the console.
                     Note that this applies only to the diagnostic messages
                     audomon generates concerning the status of the audit
                     system.  Error messages caused by wrong usage of
                     audomon are sent to the standard output (where audomon
                     is invoked).

 WARNINGS    [Toc]    [Back]
      All modifications made to the audit system are lost upon reboot.  To
      make the changes permanent, set AUDOMON_ARGS in
      /etc/rc.config.d/auditing.
