Configuring how events are sent

When you initialize your tracker (using the init method), you will need to provide its network configuration as an associative array under the network property. The configuration consists of the collector endpoint and HTTP method type (see below table).

Example: = { network: { collector: "http://...", method: "POST" } }
Code language: PHP (php)

Properties of the network configuration:

Network configuration parameterDescription
collectorURI for the Snowplow collector endpoint.
methodHTTP method to use. GET and POST methods are supported.

Tracker namespaces

You may initialize multiple trackers, each with a different namespace. In this way, you can send events to multiple Snowplow collectors from your application. An example scenario for this would be sending events to both a staging and production pipeline. Each tracker processes events in its own background thread.

To initialize a tracker with a custom namespace, set the namespace property in the associative array passed to the init method. When no namespace is given, a default namespace is assigned to the tracker. Reinitializing trackers with the same namespace results in updating the configuration for the already initialized trackers. The following example initializes a tracker with the namespace “ns1”: = { namespace: "ns1", network: { ... } }
Code language: JavaScript (javascript)

Trackers can be individually addressed using their namespaces when tracking events. To send events to a specific tracker, call its namespace as follows: = {...}. Here is an example of tracking a screen view event using a tracker with the namespace “ns1”: = { id: "screen23", name: "HUD > Save Game" }
Code language: PHP (php)

To track events with all initialized trackers, simply call methods to track events on the Snowplow instance without specifying a tracker namespace. The following example tracks a screen view event using all initialized trackers: = { id: "screen23", name: "HUD > Save Game" }
Code language: PHP (php)


The package makes use of roku-log, a logging framework for Roku Scenegraph apps. roku-log enables configuring the logging output and setting log levels for the severity of the output. Under the debug log level, the tracker outputs information about each request. On the other hand, setting the log level to error will only output crashes and tracking errors. Please refer to the roku-log instructions to learn about setting it up.
