Installing Supervisor—a process manager

We have begun to accumulate quite a few of programs in our software stack.

In order to facilitate easy and consistent operation of these programs, we can use an excellent tool called Supervisor (http://supervisord.org) to help us.

As it so happens, there is a Buildout recipe to make configuration file generation easy called collective.recipe.supervisor (http://pypi.python.org/pypi/collective.recipe.supervisor). This one is too easy and simple to resist (hence its popularity).

In 06-deployment-optimization-supervisor.cfg, we have:

[buildout]
extends = 06-deployment-optimization-pound-config.cfg
parts += supervisor

[pound]
directory = ${buildout:directory}/parts/pound-install__compile__

[supervisor]
recipe = collective.recipe.supervisor
programs =
#Prio    Name        Program                              Params
