Prometheus

Metrics Collection and Alerting for Modern Systems

Definition

Prometheus is an open-source monitoring system designed for collecting, storing, and querying time-series metrics from applications and infrastructure. It is widely used in cloud-native and Kubernetes environments. Often referred to as a metrics monitoring platform, Prometheus is a core component of modern observability stacks. 

Why It Is Used

Metrics are foundational to understanding system health and performance. Prometheus provides a reliable, scalable way to collect and analyse metrics in dynamic environments, enabling teams to detect issues early and make data-driven operational decisions. 

How It Is Used

Prometheus periodically scrapes metrics endpoints exposed by applications and infrastructure. The collected data is stored locally and queried using PromQL. Alerting rules evaluate metrics and trigger notifications when conditions are met, often via Alertmanager. 

Key Benefits

BuildPiper Relevance

BuildPiper integrates Prometheus metrics into its observability and release workflows. By correlating metrics with deployments and environments, BuildPiper helps teams understand the operational impact of releases and respond to issues faster. 

Frequently Asked Questions

Is Prometheus a monitoring or observability tool?

Prometheus is primarily a monitoring and metrics collection tool. It often forms the metrics backbone of broader observability platforms when combined with logs and traces.

No. Prometheus collects and stores metrics, while Grafana is commonly used to visualise Prometheus data through dashboards.

BuildPiper uses Prometheus data to assess deployment health, track reliability metrics, and correlate operational signals with release activity.
