+.TH WATCHQUAGGA 8 "July 2010"
+.SH NAME
+watchquagga \- a program to monitor the status of quagga daemons
+.SH SYNOPSIS
+.B watchquagga
+.RI [ option ...]
+.IR daemon ...
+.br
+.B watchquagga
+.BR \-h " | " \-v
+.SH DESCRIPTION
+.B watchquagga
+is a watchdog program that monitors the status of supplied quagga
+.IR daemon s
+and tries to restart them in case they become unresponsive or shut down.
+.PP
+To determine whether a daemon is running, it tries to connect to the
+daemon's VTY UNIX stream socket, and send echo commands to ensure the
+daemon responds. When the daemon crashes, EOF is received from the socket,
+so that watchquagga can react immediately.
+.PP
+This program can run in one of the following 5 modes:
+.TP
+.B Mode 0: monitor
+In this mode, the program serves as a monitor and reports status changes.
+.IP
+Example usage: watchquagga \-d zebra ospfd bgpd
+.TP
+.B Mode 1: global restart
+In this mode, whenever a daemon hangs or crashes, the given command is used
+to restart all watched daemons.
+.IP
+Example usage: watchquagga \-dz \e
+.br
+-R '/sbin/service zebra restart; /sbin/service ospfd restart' \e
+.br
+zebra ospfd
+.TP
+.B Mode 2: individual daemon restart
+In this mode, whenever a single daemon hangs or crashes, the given command
+is used to restart this daemon only.
+.IP
+Example usage: watchquagga \-dz \-r '/sbin/service %s restart' \e
+.br
+zebra ospfd bgpd
+.TP
+.B Mode 3: phased zebra restart
+In this mode, whenever a single daemon hangs or crashes, the given command
+is used to restart this daemon only. The only exception is the zebra
+daemon; in this case, the following steps are taken: (1) all other daemons
+are stopped, (2) zebra is restarted, and (3) other daemons are started
+again.
+.IP
+Example usage: watchquagga \-adz \-r '/sbin/service %s restart' \e
+.br
+\-s '/sbin/service %s start' \e
+.br
+\-k '/sbin/service %s stop' zebra ospfd bgpd
+.TP
+.B Mode 4: phased global restart for any failure
+In this mode, whenever a single daemon hangs or crashes, the following
+steps are taken: (1) all other daemons are stopped, (2) zebra is restarted,
+and (3) other daemons are started again.
+.IP
+Example usage: watchquagga \-Adz \-r '/sbin/service %s restart' \e
+.br
+\-s '/sbin/service %s start' \e
+.br
+\-k '/sbin/service %s stop' zebra ospfd bgpd
+.PP
+Important: It is believed that mode 2 (individual daemon restart) is not
+safe, and mode 3 (phased zebra restart) may not be safe with certain
+routing daemons.
+.PP
+In order to avoid restarting the daemons in quick succession, you can
+supply the
+.B \-m
+and
+.B \-M
+options to set the minimum and maximum delay between the restart commands.
+The minimum restart delay is recalculated each time a restart is attempted.
+If the time since the last restart attempt exceeds twice the value of
+.BR \-M ,
+the restart delay is set to the value of
+.BR \-m ,
+otherwise the interval is doubled (but capped at the value of
+.BR \-M ).
+.SH OPTIONS
+.TP
+.BR \-d ", " \-\-daemon
+Run in daemon mode. When supplied, error messages are sent to Syslog
+instead of standard output (stdout).
+.TP
+.BI \-S " directory" "\fR, \fB\-\-statedir " directory
+Set the VTY socket
+.I directory
+(the default value is "/var/run/quagga").
+.TP
+.BR \-e ", " \-\-no\-echo
+Do not ping the daemons to test whether they respond. This option is
+necessary if one or more daemons do not support the echo command.
+.TP
+.BI \-l " level" "\fR, \fB\-\-loglevel " level
+Set the logging
+.I level
+(the default value is "6"). The value should range from 0 (LOG_EMERG) to 7
+(LOG_DEBUG), but higher number can be supplied if extra debugging messages
+are required.
+.TP
+.BI \-m " number" "\fR, \fB\-\-min\-restart\-interval " number
+Set the minimum
+.I number
+of seconds to wait between invocations of the daemon restart commands (the
+default value is "60").
+.TP
+.BI \-M " number" "\fR, \fB\-\-max\-restart\-interval " number
+Set the maximum
+.I number
+of seconds to wait between invocations of the daemon restart commands (the
+default value is "600").
+.TP
+.BI \-i " number" "\fR, \fB\-\-interval " number
+Set the status polling interval in seconds (the default value is "5").
+.TP
+.BI \-t " number" "\fR, \fB\-\-timeout " number
+Set the unresponsiveness timeout in seconds (the default value is "10").
+.TP
+.BI \-T " number" "\fR, \fB\-\-restart\-timeout " number
+Set the restart (kill) timeout in seconds (the default value is "20"). If
+any background jobs are still running after this period has elapsed, they
+will be killed.
+.TP
+.BI \-r " command" "\fR, \fB\-\-restart " command
+Supply a Bourne shell
+.I command
+to restart a single daemon. The command string should contain the '%s'
+placeholder to be substituted with the daemon name.
+.IP
+Note that
+.B \-r
+and
+.B \-R
+options are not compatible.
+.TP
+.BI \-s " command" "\fR, \fB\-\-start\-command " command
+Supply a Bourne shell
+.I command
+to start a single daemon. The command string should contain the '%s'
+placeholder to be substituted with the daemon name.
+.TP
+.BI \-k " command" "\fR, \fB\-\-kill\-command " command
+Supply a Bourne shell
+.I command
+to stop a single daemon. The command string should contain the '%s'
+placeholder to be substituted with the daemon name.
+.TP
+.BR \-R ", " \-\-restart\-all
+When one or more daemons are shut down, try to restart them using the
+Bourne shell command supplied on the command line.
+.IP
+Note that
+.B \-r
+and
+.B \-R
+options are not compatible.
+.TP
+.BR \-z ", " \-\-unresponsive\-restart
+When a daemon is in an unresponsive state, treat it as being shut down for
+the restart purposes.
+.TP
+.BR \-a ", " \-\-all\-restart
+When zebra hangs or crashes, restart all daemons taking the following
+steps: (1) stop all other daemons, (2) restart zebra, and (3) start other
+daemons again.
+.IP
+Note that this option also requires
+.BR \-r ,
+.BR \-s ,
+and
+.B \-k
+options to be specified.
+.TP
+.BR \-A ", " \-\-always\-all\-restart
+When any daemon (i.e., not just zebra) hangs or crashes, restart all
+daemons taking the following steps: (1) stop all other daemons, (2) restart
+zebra, and (3) start other daemons again.
+.IP
+Note that this option also requires
+.BR \-r ,
+.BR \-s ,
+and
+.B \-k
+options to be specified.
+.TP
+.BI \-p " filename" "\fR, \fB\-\-pid\-file " filename
+Set the process identifier
+.I filename
+(the default value is "/var/run/quagga/watchquagga.pid").
+.TP
+.BI \-b " string" "\fR, \fB\-\-blank\-string " string
+When the supplied
+.I string
+is found in any of the command line option arguments (i.e.,
+.BR \-r ,
+.BR \-s ,
+.BR \-k ,
+or
+.BR \-R ),
+replace it with a space.
+.IP
+This is an ugly hack to circumvent problems with passing the command line
+arguments containing embedded spaces.
