;; this file is a walkthrough of Moustache features, a web framework for Clojure
;; http://github.com/cgrand/moustache/tree/master

;; Moustache allows to declare routes, apply middlewares and dispatch on http methods.
;; Moustache is compatible with all frameworks built on Ring, including Compojure

Here are simple steps to install Datadog's agent on FC17. These steps are meant to be work-arounds until we officially support Fedora Core.

Steps

If you have /etc/yum.repos.d/datadog.repo, delete that file and run sudo yum makecache

Install python-tornado from FC repositories

sudo yum install python-tornado-2.2.1-1.fc17

# Create the datadog user with select only permissions:
#  CREATE USER datadog WITH PASSWORD '<complex_password>';
#
# Grant select permissions on a table or view that you want to monitor:
#  GRANT SELECT ON <schema>.<table> TO datadog;
#
# Grant permissions for a specific column on a table or view that you want to monitor:
#  GRANT SELECT (id, name) ON <schema>.<table> TO datadog;
#
# Let non-superusers look at pg_stat_activity in a read-only fashon.

The Challenge

1. Sign up for Datadog, get the agent reporting metrics from your local machine. Bonus question- what is the agent?

2. Submit an event via the API.

3. Get an event to appear in your email inbox (the email address you signed up for the account with)

Installation

To install, place datadog.py in your callback plugins directory. If you don't yet have one, run:

mkdir -p plugins/callback

Then place the following in your ansible.cfg file:

[defaults]

callback_plugins = ./plugins/callback
