Tags are labels which can be given to pages of your website. Adding tags gives you powerful methods of filtering data in your Application so you can easily see the performance difference between two (or more) versions of the same resource.
Before you can add tags you first need to setup Real User Monitoring. Learn more about setting up RUM here.
Tags can be added by calling the 'withTags' method on the Raygun4JS provider. Each tag included will be added to the page along with every virtual page, asset and XHR performance metric used on that page.
// Enable RUM & Crash Reporting options above rg4js('withTags', ['tag-1', 'tag-2']);
note: A session includes every tag in each page/virtual page in that session.
