# This is an example of metaprogramming in the Elixir language.
# 
# We will define a domain specific language (DSL) for the definition
# of a service which is watched by several sensors.
# Each sensor watches some property/functionality of the service and
# returns the result of the check.
# 
# To determine if the service is functioning properly, we need functions
# to run all the sensors' code and gather the returned data.

encfs-agent 

Mounts encfs filesystems with passwords generated using private keys stored in ssh-agent.
You can have any number of encrypted filesystems ("vaults") under VAULTS_DIR. Password for 
each of them is derived from its name and given private key stored in ssh-agent.
You can use ssh-askpass for ssh-agent if you want.

# Simple Phoenix authentication plug

# - based on Plug's session store
# - redirects unauthenticated requests to login page "/login/<request url>"
# - /static/... requests are not authenticated 
# - authentication is valid as long as session is valid (you can change this behaviour easily)

# Because we need session to be fetched BEFORE this plug, we must put this to router.ex:
