Title Body

I've recently become quite fond of Upstart. Previously I've been using God, Monit and Bluepill but I don't really like these solutions so I'm giving Upstart a try. I've been using the Foreman gem to generate some basic Upstart configuration files for my processes in /etc/init . However, these generated files only handle the respawning of a crashed process. I was wondering whether it's possible to tell Upstart to restart a process that's consuming for example > 150mb of memory, as you would with Monit, God or Bluepill. I read through the Upstart docs and this looks like the thing I'm looking for. Though I have no clue how to config something like this. What I basically want is quite simple. I want to restart my web process if the memory usage is > 150mb ram. These are the files I have: |-- myapp-web-1.conf |-- myapp-web-2.conf |-- myapp-web-3.conf |-- myapp-web.conf |-- myapp.conf And their contents are: myapp.conf pre-start script bash << "EOF" mkdir -p /var/log/myapp chown -R deployer /var/log/myapp EOF end script myapp-web.conf start on starting myapp stop on stopping myapp myapp-web-1.conf / myapp-web-2.conf / myapp-web-3.conf start on starting myapp-web stop on stopping myapp-web respawn exec su - deployer -c 'cd /var/applications/releases/20110607140607; cd myapp && bundle exec unicorn -p $PORT >> /var/log/myapp/web-1.log 2>&1' Any help much appreciated!
