SYNOPSIS
kitd |
[-d] [-c
cooloff] [-m
maximum] [-n
name] [-t
restart] command ... |
DESCRIPTION
Thekitd daemon supervises a child process, redirecting
its standard output and standard error to
syslog(3). When the child process exits, it
is automatically restarted using exponential backoff.
The options are as follows:
-ccooloff- The interval for which the child process must live before the restart
interval is reset to its initial value.
The interval may have a suffix of s, m, h or d for seconds, minutes, hours or days, respectively. Otherwise, the interval is in milliseconds.
The default cooloff interval is 15m.
-d- Do not daemonize. Log to standard error as well as syslog(3).
-mmaximum- The maximum interval between restarts.
The interval is interpreted as with
-c. The default maximum interval is 1h. -nname- Set the name of the process and the logging prefix. The default is the last path component of command.
-trestart- The initial interval between restarts. This interval is doubled each time
the child process is restarted.
The interval is interpreted as with
-c. The default restart interval is 1s.
kitd responds to the following
signals:
SIGTERM|SIGINT- The signal is forwarded to the child process.
kitdexits. SIGINFO- The status of the child process is logged.
SIGHUP|SIGUSR1|SIGUSR2- The signal is forwarded to the child process.
EXAMPLES
To set up supervisors for pounce(1):
# ln -s kitd /etc/rc.d/pounce_tilde # ln -s kitd /etc/rc.d/pounce_libera # rcctl enable pounce_tilde pounce_libera # rcctl set pounce_tilde user _pounce # rcctl set pounce_tilde flags pounce -h irc.tilde.chat defaults.conf # rcctl set pounce_libera user _pounce # rcctl set pounce_libera flags pounce -h irc.libera.chat defaults.conf # rcctl start pounce_tilde pounce_libera
