Tell about your experience using Grafana in projects.

In Java projects, I used Grafana for visualizing metrics and monitoring the state of applications and infrastructure. Usually, data was collected using Prometheus, which integrated with the application via JMX Exporter or Micrometer. In Grafana, I set up dashboards with graphs showing CPU load, memory usage, request count, and response time. This allowed for quick identification of bottlenecks and anomalies in service operation.

Example of setting up metrics with Micrometer in Spring Boot:

@Bean
public MeterRegistryCustomizer<MeterRegistry> metricsCommonTags() {
    return registry -> registry.config().commonTags("application", "my-app");
}

Then, these metrics were collected by Prometheus and displayed in Grafana for convenient monitoring.
