Service monitoring with daemontools

This is a reference for setting up various daemons (services) under djb's excellent daemontools package, which provides tools for the supervision, monitoring, and control of system processes, as well as an assortment of other useful utilities. Some of these scripts make use of software included in djb's ucspi-tcp package.

The rationale for using daemontools and ucspi-tcp is available on djb's site. Suffice it to say that any competent systems engineer will immediately recognize the benefits of these packages.

I recommend the use of /var/spool/supervise to contain supervise directories. I've seen /etc/supervise used as well.

Shameless plug: I am available to set up any of this software on either a full-time employment or consulting/contracting basis. Feel free to inquire.

Shell scripts (`run`) for various services:

makedir

#!/bin/bash    if [ "$2" == "" ]; then    echo -e "\nUsage: $0 dir loguser\n";    exit 100  fi    mkdir -p $1/log/main  chown $2 $1/log/main    echo -e "#!/bin/sh\nexec 2>&1" > $1/run  echo -e "#!/bin/sh\nexec setuidgid $2 multilog t ./main" > $1/log/run    chmod 0755 $1/run $1/log/run

makedir-auto

#!/bin/bash    if [ "$3" == "" ]; then    echo -e "\nUsage: $0 dir loguser runcmd\n";    exit 100  fi    mkdir -p $1/log/main  chown $2 $1/log/main    echo -e "#!/bin/sh\nexec 2>&1\nexec $3" > $1/run  echo -e "#!/bin/sh\nexec setuidgid $2 multilog t ./main" > $1/log/run    chmod 0755 $1/run $1/log/run  ln -s /var/spool/supervise/$1 /service
