Have you conducted metrics collection and analysis directly from servers in a production environment in your last project?

Yes, collecting and analyzing metrics from servers in a production environment is an important practice for monitoring the state of the application and infrastructure. Typically, tools such as Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana), or specialized agents (e.g., Micrometer in Java) are used.

Within a project, you can configure the collection of metrics such as CPU, memory, response time, request count, errors, and other indicators. This data helps quickly identify problems and optimize service performance.

For example, in a Java application, you can integrate Micrometer to collect metrics and export them to Prometheus, then visualize them in Grafana. This allows for real-time metrics collection and dashboard creation for analysis.
