These development and testing practices ensure the performance of critical applications and resources to deliver loyalty-building user experiences. Real user monitoring (RUM) is a performance monitoring process that collects detailed data about users’ interactions with an application. What is real user monitoring?

Any time you run a test with WebPageTest, you’ll get this table of different milestones and metrics. Note the bottom row shows me the Standard Deviation of the tests’ results. Higher variance means a less stable metric across pages. With my pen and paper, I’ll make a note of investigating these specifically in my testing.

Most monitoring tools for migrations, development, and operations focus on collecting and aggregating the three pillars of observability— metrics, traces, and logs. Using a data-driven approach to size Azure resources, Dynatrace OneAgent captures host metrics out-of-the-box to assess CPU, memory, and network utilization on a VM host.

To prepare ourselves for a big change in the tech stack of our endpoint, we decided to track metrics around the time taken to respond to queries. After some consultation with our backend teams, we determined the most effective way to group these metrics were by UI screen. For the migration, testing was a first-class citizen.

To accomplish this goal, an organization needs to build internal processes and procedures that can operationalize a performance-first culture. According to Tim Kadlec : A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed and that is used to guide design and development.
