Project for blog post Coding Kata: Site Heartbeat in Elixir and Golang.

Uses https://github.com/edgurgel/httpoison

Deployment

• Build it as escript locally,

  mix escript.build

• scp the site_heartbeat to target system (e.g. ~/site-heartbeat).

• Maintain a valuable hosts.txt.

• Run it for test

  ./site-heartbeat/site_heartbeat hosts.txt

• Put it into the crontab - running hourly

  5 * * * * cd /var/www/vhosts/rh-flow.de/site-heartbeat; ./site_heartbeat hosts.txt

• Add locales to the cronjob, otherwise "the VM is running with native name encoding of latin1 which may cause Elixir to malfunction as it expects utf8"

  LANG="de_DE.utf8" LANGUAGE="de_DE:" LC_ALL=de_DE.UTF-8
