For people running the web app using paster http server (usually behind a web server acting as a reverse proxy), what kind of tool do you use to monitor your app server (e.g. paster) ?
I've heard of supervisor, daemontools etc, but for my purpose a simple shell script which acts as a parent process of python/paster and just restarts it when it dies is sufficient. So, the script I came up with is : #!/bin/bash test -f $2 && exit echo $$ > $2 trap 'kill $!; rm $2; exit' SIGTERM while true; do $1 & wait; sleep 20; done You use it by passing the command you want to execute and the name of a file to store the process id (which must not exist beforehand), for example: $ monitor "paster serve production.ini" main.pid & To terminate the monitor as well as the app it's monitoring (the monitor script will kill the child app as well as remove the pid file): $ kill $(cat main.pid) If for any reason the monitored application terminates, then the monitor script will restart it after 20 seconds. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
