NAME    [Toc]    [Back]

     imdmonitor	- daemon that monitors filesystems and launches	alerts

SYNOPSIS    [Toc]    [Back]


DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]


     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

     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
