Stupid simple website uptime monitor. Run a rake task and get notified by
Airbrake if the site unreachable (essentially any response other than 2xx).
Usage:
rake heartbeat URI=http://example.com AIRBRAKE_API_KEY=...
You can also set PULSE_RATE=n where n is the number of seconds to sleep
between pulses. The default is 60.
Designed to run as a worker on Heroku:
git@github.com:grays/heartbeat.git
cd heartbeat
heroku apps:create my-heartbeat --stack cedar
heroku config:add URI=http://example.com AIRBRAKE_API_KEY=...
git push heroku master
heroku scale worker=1
