kolekti-server 0.0.1

Lightweight monitoring system

TESTS	COVERAGE

Kolekti is a metric gatherer with lightweight agents.

Current status: Under Heavy development

Installation

Because Kolekti is under heavy development, the only way to install it is by cloning this repository.

Defaults will use a local sqlite with RabbitMQ for tasks. You can reconfigure it under server/app/settings.py or create your own settings and set the environment variable DJANGO_SETTINGS_MODULE.

You can use Uchiwa with this configuration:

{
  "sensu": [
    {
      "name": "Kolekti 1",
      "host": "localhost",
      "port": 9996,
      "path": "/sensu"
    }
  ],
  "uchiwa": {
    "host": "0.0.0.0",
    "port": 3000,
    "refresh": 5
  }
}

By default, Kolekti server will listen on port 9996, and will serve the Sensu API on path /sensu.

To create the database you can use:

python server/manage.py syncdb

Developers

You can create fake data by running:

python server/manage.py sample_kolekti
