New Relic: Track Website Transactions
This app gives you access to the New Relic service (free), which tracks website transactions and back-end application activity in real time. Importantly, the app is not a simplified viewer.
An ecommerce retailer can monitor about 85,000 transactions per minute, for example, and not just a simple subset of those transactions. The app has the same color-coded charts as the Web-based New Relic app to help make those massive data sets easier to comprehend.
