Creating an area chart of the application's functional statistics

Understanding not only how your web page is performing and responding to requests but also how underlying applications that you rely on is critical to the success of any website. You need to have a constant pulse on how the application is behaving and if any trends are emerging or correlations are being observed between interdependent pieces of data. The experience a customer has with your website is reliant on the constant high performance of all its components.

In this recipe, you will write a Splunk search using the timechart command to plot web application memory and response time statistics over a given time period. You will then graphically present these values using an area ...
