.TH "vmon" "8" "January 1997" "Speak 0.2" "Text-to-Speech"
.PP
.SH NAME
.PP
\fBvmon\fP - monitor system status (town crier).
.PP
.SH SYNOPSIS
.PP
\fBvmon\fP \fIfilesystems\fP
.br
\fBvstat\fP \fIfilesystems\fP
.PP
.SH DESCRIPTION
.PP
The Text-to-speech package introduces a standard TCP/IP port service for
attaching text-to-speech resources to your network. These resources can
be used to monitor system status, provide verbal alarms, etc. This network
service may be accessed by telnetting to a machine running a "speak" server,
or by using the various application utilities, such as \fBvmon\fP.
.PP
The \fBvmon\fP program will monitor the specified list of file systems.
If any of these file systems exceed a maximum "quota" (such as over 90%
capacity in blocks or i-node use), then the monitor will send verbal
alerts every 5 minutes. This quota, and other parameters for vmon, may
be found in the [\fIvmon\fP] section of \fBspeak.conf\fP.
.PP
The \fBvmon\fP program will also announce current system status once
every hour. This system status includes the total used capacity of
all file systems being monitored, how long the system has been up, and
how many users are currently logged in (excluding root). This hourly
announcement can be used to determine a given system is still alive.
.PP
The \fBvmon\fP program will now also monitor specified user mailboxes
for new mail and announce when new mail arrives. The users to be
monitored are specified in the [\fIvmon\fP] section of \fBspeak.conf\fP.
Simply list mailbox= entries for each mailbox you wish to monitor. See
the example speak.conf included with the distribution.
.PP
The \fBvmon\fP program can also be ran as \fBvstat\fP. When used as
\fBvstat\fP, the program performs an immediate system check, announces,
and then terminates. You can either use \fBvstat\fP from a crontab or
start \fBvmon\fP from \fBspeak.init\fP. You may also start \fBvmon\fP
from a \fBrc.local\fP file. Please check the \fBspeak.init\fP file
to add any file systems you wish to monitor. By default, the root
filesystem is enabled in \fBspeak.init\fP.
.PP
A mute option may also be specified in the [\fIvmon\fP] section of
\fBspeak.conf\fP. This option mutes voice output during certain times of
the day. This is normally specified by 24 hour clock in hours, hence 18-7
means to mute output anytime after 18' hours (6pm) and anytime before 7'
hours (7am).
