#mod_health

Monitor Ejabberd and any applications running on it. Based on https://github.com/nycholas/ which is based on https://www.ejabberd.im/mod_monitor_web 14.02+

Objective

The target is to include the status code on the response of the healthcheck on the response status code.

• 204 response for all checked and properly running.
• 503 response when any of the services defined on the module are failling.

Ejabberd Config

First make sure the module is added in ejabberd.yml on the server port

  -
    port: 5281
    module: ejabberd_http
    request_handlers:
      "/healthcheck": mod_health
    web_admin: false
    http_poll: false
    http_bind: false
    ## register: true
    captcha: true

This will create an endpoint for mod_health to listen to at localhost:5281/healthcheck

Adding additional applications to check

Define the application name as a constant at the top of the file:

-define(MYSQL, mysql).

then add subsecuently on function get_all_status another check variable for the new status added (like: EJABBERDStatus = lists:keymember(?EJABBERD, 1, application:which_applications()),), add this new obtained variable status to the list of results.
