rb-arubacentral

Aruba Central is a cloud-based network management platform, similar to ALE (Aruba Location Engine) and Cisco MSE (Mobility Services Engine). It is developed by Aruba Networks, a Hewlett Packard Enterprise company. Aruba Central provides centralized management and monitoring of Aruba network devices, such as switches, routers, and wireless access points.

The goal of the Aruba Central service is to fetch data from Aruba Central APs and transform it into real-time actionable information to track the mobility of people connected to Aruba Central APs.

1. Workflow

The rb-arubacentral service processes data from the Aruba Central REST API. After retrieving the data, it generates two types of objects: the AP status and the mobility data. It then generates Kafka events and sends them to the Kafka broker in batches with the location data and the APs status data.

2. Caching

The rb-arubacentral can cache data for common requests. This is done to reduce API calls to the Aruba Central REST. The service first checks if the request is in the cache list. If it's not, then it will call the Aruba Central service as usual. If it's in the list, it will retrieve the data from the cache. Subsequently, it will read from the cache until it expires and then refresh its cache again by calling the REST.

4. How to install?

The rb-arubacentral has been tested on ruby 2.1.2 and ruby 2.1.9, you can install and run the program executing the following instructions

cd rb-arubacentral
rvm install 2.1.2
bundle install

4.1 Running

For running the service you can pass custom config file using -c, for example ruby ./bin/rb_arubacentral.rb -c /path/to/my/config.yml or you can just run ruby ./bin/rb_arubacentral.rb and it will take the default config file.
