monitoring-mock

monitoring-mock is a super simple system for testing new monitoring concepts.

This allows you to simulate a hierarchical network e.g. datacenters, hosts and services. A simulated outage affect all systems below the broken one.

Installation

$ git clone https://github.com/mariussturm/monitoring-mock.git
$ cd monitoring-mock
$ bundle install

Configuration

Configure your nework.

$ vi etc/mock.yaml

Define a type for every entry.

Sample configuration

---
  /green:
    type: datacenter
  /green/web1:
    type: host
  /green/web1/http:
    type: service
  /green/mail1:
    type: host
  /green/mail1/smtp:
    type: service
  /blue:
    type: datacenter
  /blue/web2:
    type: host
  /blue/web2/smtp:
    type: service

Start the mock

$ ruby mm.rb

Or use your rack server of choice

$ ruby mm.rb -s thin

Dashboard

You can get an overview of your simulated network under

http://localhost:4567/dashboard

Press the Ok or Critical button to toggle the state of an entry

Use the mock

Every mock entry can be checked via HTTP. The mock delivers a JSON string as result.

$ curl http://localhost:4567/green
{"status":0,"output":"Service OK","options":{"type":"datacenter"}}

$ curl http://localhost:4567/green/web1
{"status":2,"output":"Service is broken","options":{"type":"host"}}
