Can you share your experience using the Prometheus monitoring system in projects?

Prometheus is an open-source monitoring and alerting system widely used for collecting metrics from applications and infrastructure.

In my experience with Prometheus, I used it for:

• Collecting metrics from microservices via HTTP endpoint /metrics.
• Setting up alerting rules with Alertmanager to notify about issues.
• Visualizing metrics using Grafana.

For example, to monitor service performance, I added metric exporters (like request counters, response times) in the code, which Prometheus regularly polls. This allowed quick detection of bottlenecks and anomalies.

Prometheus also integrates well with Kubernetes, enabling automatic discovery of services and metrics collection without additional configuration.
