The development of the Internet of Things is set to have a strong impact on many aspects of society. Test-beds and experimental facilities, both of small scale and up to city scale, will be an essential enabler to facilitate the development of this vision. Facilitating the access to these test-beds to a large community of experimenters approach is a key asset to the development of a large and active community of application developers, necessary to address the many challenges faced by European and Japanese societies.
FESTIVAL project’s vision is to provide IoT experimentation platforms providing interaction facility with physical environments and end-users, where experimenters can validate their Smart ICT service developments in various domains such as smart city, smart building, smart public services, smart shopping, participatory sensing, etc. FESTIVAL testbeds will connect cyber world to the physical world, from large scale deployments at a city scale, to small platforms in lab environments and dedicated physical spaces simulating real-life settings. Those platforms will be connected and federated via homogeneous access APIs with an “Experimentation as a Service” (EaaS) model for experimenters to test their added value services.
fluent-plugin-festival provides input plugin for FESTIVAL platform.
Installation
gem install fluent-plugin-festival
fluent-plugin-festival requires Ruby version >= 2.1.0.
Usage
fluent-plugin-festival has Input Plugins for FESTIVAL platform.
Input Plugin (Fluent::FestivalInput)
Input Plugin can receive events from FESTIVAL EaaS API Server. It can be used via source directive in the configuration. Since FESTIVAL platform requires an authentication, before subscribing resource information, the user needs to create own FESTIVAL platform account via FESTIVAL portal. After creating an account, please make a configuration file with source directive. detail options of source directive is as follows.
<source>
@type festival
tag tag_name
username festival_portal_login_name
password festival_portal_password

tag (required): Tag name appended to the input data inside fluentd network
polling_interval (optional): Polling interval (seconds) for accessing EaaS API (default: 60 seconds)
resource (at least one entry is required): The target resources to obtain sensor data. multiple resources can be specified by multiple tags. If a user wants to specify different polling interval for each resource, it must be specified different tags.
path (at least one entry is required): The target resource path name should be specified. The pathname should specify only under aggregator part and target data type. Currently, only "current_data" type is supported.
(e.g. /aggregators/IOT-0/testbeds/jose/resources/hyogo001_barometer-info-value/current_data).
If the time field is empty, this plugin automatically set the finished time of data downloading. If multiple sensor data specified simultaneously, the time difference may become larger than single datum case. A sample data format is shown below.
