icco / creepermon

A ruby app to watch your servers.

Creepermon

Creepermon is an app for monitoring websites in a really stupid way. It doesn't do alerting. It just curls your websites and creates graphs.

Architecture

Creepermon takes a yaml file that defines a list. Each item in the list is a url and html xpath. We log each scrape to Keen.io and build a nice dashboard to show you all of your sites.

Each scrape collects:

• Status code
• Scrape time
• Value to xpath target

The value of the xpath target is turned into an integer before storage.

Installation

Clone, change sites.yml, push to heroku.

Set Heroku config:

heroku config:set KEEN_PROJECT_ID=aaaaaaaaaaaaaaaaaaaaaaaa KEEN_READ_KEY=eeeeeeeeeeeeeeeeeeeeeeee KEEN_WRITE_KEY=ffffffffffffffffffffffff
heroku config:set LANG=en_US.UTF-8
heroku config:set RACK_ENV=production

Add the Heroku Scheduler

heroku addons:create scheduler:standard

Then add rake cron to run every ten minutes
