The Transactions page is a summary of the tiniest transaction details. This data will help you track the page with the slowest response time, the most dissatisfying Apdex score, or the highest throughput. All these measurements are key indicators to find the source of the optimization problem. Here’s an overview of the Transactions page:
The Transaction trace tab will give you hints on where your overloading comes from. It’s a very helpful feature to define which pages of your website have potential performance issues.
External services monitoring
Using external services is often tricky. Even if you lose control to a third-party application, New Relic will provide you feedback on the performance of these APIs. Like the HTTP transaction with your server, you can also track the time consumption, the average response time, or the throughput RPM (requests per minute) of an external service:
Configuring customized alerts
New Relic can alert you when your server is overloaded with custom notifications. You will be notified when your Apdex score is under the threshold you have configured. For example, if your Apdex score is under 0.7 (which means less than 70% of the requests are “satisfied”), you will get an alert by e-mail or on your mobile phone explaining the current issue.
Service Level Agreement reports
Service Level Agreement (SLA) reports will allow you monitor day-by-day metrics on your websites. Your SLA reports are available via Reports | SLA. New Relic is useful for tracking user satisfaction through the load time and the Apdex score. These measures are relevant because they give you insights into what the user experience was at any given moment. The SLA reports provide such data to you on a daily basis. Tracking the variations in your loading time or Apdex score is essential in order to monitor your optimization process.
A web scenario is a series of visited pages (steps) executed one after another. It closely resembles the behavior of a real visitor to your website. When a step has an error, the web scenario stops and does not perform the following steps. Red bars will appear on the graphs. Web scenarios are the main feature of Quanta computing and are really helpful to ensure that, in addition to the eventual errors a page can generate, the page itself renders the expected content.
