imdmonitor(1M)

NAME
     imdmonitor - daemon that monitors filesystems and launches alerts

SYNOPSIS
     /usr/sbin/imdmonitor

DESCRIPTION
     imdmonitor runs in the background and monitors available space on mounted
     filesystems and requests for message alerts from the sysmon(1M) facility.
     When it detects a condition requiring a graphical alert notifier, it uses
     fork(2) to launch a new process to post the notifier.  The
     /usr/lib/sysmon/errhook program posts the notifier.

     imdmonitor is launched at login from the /var/X11/xdm/Xsession.dt script.
     It is not intended to be run directly by end users.  It establishes a
     connection to the X server, and exits automatically when that connection
     is closed (typically when the desktop user logs out).

     Default filesystem monitoring is to notify when any mounted, writable
     filesystem becomes more than 95% full.  imdmonitor will notify a second
     time when half the remaining space has been used and will notify a third
     time when all the space is used.

     The monitoring configuration can be changed with the "Set Space
     Monitoring" task, available in the system manager from the "Files and
     Data" section.  The system manager can be launched from the toolchest
     (System > System Manager).


FILES
     $HOME/.desktophost/<hostname>/fsNotifyConfig
     /var/adm/sysmon.msg
     /etc/mtab


     The imdmonitor program uses fam(3X) to watch three files and reacts when
     they change.  The file $HOME/.desktophost/<hostname>/fsNotifyConfig
     defines the percentage full for each filesystem the user wants monitored.
     The "Set Space Monitoring" task records the user's preferences to this
     file.  When this file changes, imdmonitor updates its internal monitoring
     levels.


     The file /var/adm/sysmon.msg contains the latest system alert message
     generated by sysmon.  When this file changes, imdmonitor posts the file's
     contents in an error dialog.


     The file /etc/mtab contains the list of filesystems to monitor.  When
     this file changes, imdmonitor stop monitoring filesystems no longer in
     the list and begins monitoring new filesystems that were added to the
     list.
