Adding an Iglu Repository

1. Head to the extension pane in the Dev Tools, and hit theManage Schemas button in the top toolbar

2. In the bottom right, hitRegistries…​, thenAdd

3. Fill out the details for you new Registry and save

4. Note your browser will request permission for the Extension to access the registries' Domain, this may happen in the main browser window rather than the Dev Tools window if it’s not docked

5. You can also import your pipeline’s configuration using Import and supplying aresolver-config

By default we include the URL forIglu Central, which includes schemas for the built-in tracking JSONs. You can add as many repositories as you like.

Importing from Ngrok Tunnels

The Ngrok Tunnel import uses anNgrok tunnel in order to process events from remote devices.Ngrok provides a HTTP endpoint that we can use as the temporary collector endpoint.

By using this tunnel this allows you to test and debug events from additional devices and platforms including:

• A separate mobile device (using a native or React Native app)

• Server side events (e.g., server side Go codebase)

• IoT devices (smart watch, TVs)

• Any other device or implementation where you can override the Collector Endpoint

To start the tunnel ensure you have downloadedngrok locally and create a new tunnel on the device you are running Chrome and the extension on, with:

Whereexample.snplow.net is the Collector hostname that you wish to forward requests on to.This can beMicro,Mini or any other Snowplow Collector / server that responds with a 200.

Once your tunnel has started ngrok will return a HTTP/S url (under 'Forwarding') that you should then use as your Collector host.Events sent to this host will be intercepted by ngrok and forwarded to your Snowplow destination without modification.

In addition ngrok will create a Web Interface that runs onlocalhost (port4040) by default.The API for this interface is used to retrieve events and insert them into the tool.If you wish to override or change this address you can do so in the options settings of the Chrome extension by right-clicking on the icon and opening Options.

If you wish to use a static address to forward to you can do so on one of the paid ngrok plans (a few dollars a month) to avoid having the hostname being dynamic.

To start visualizing these events open the debugger and select 'Import' then 'Ngrok Tunnel' which will begin to poll (via theNgrok Agent API) for events.

To stop streaming these events select 'Import' then 'Stop Ngrok Tunnel'.
