Monitoring and metrics systems are both important parts of a DevOps engineer’s job. The interviewer may ask this question to see if you understand the differences between the two systems and how they work together. In your answer, explain what each system does and how they are similar or different from one another.
Answer: “A monitoring system is used to track the performance of a system or application. It collects data about the system’s performance and sends it to a central location where it can be analyzed. A metrics system is similar to a monitoring system in that it also collects data about the performance of a system. However, a metrics system is typically used to track specific metrics, such as the number of users on a website or the number of orders processed each day.”
