Changing Log Level

There are various log levels which can be used when initializing the plugin:

none = 0, error = 1, warn = 2, debug = 3, info = 4

Then you can pass your chosen log level when adding the plugin:

window.snowplow('addPlugin', "", ["snowplowDebugger", "DebuggerPlugin"], [ 4 ] );
Code language: JavaScript (javascript)


Adding this plugin will automatically start printing out debug logs to your Developer Tools console. This will help you debug what events are being tracked and what properties are included in each event that is being tracked and to what tracker instance.

Note: You may need to enable Verbose logs in your Developer Tools, as this plugin uses console.debug to output results.
