About Prometheus
Prometheus is an open-source monitoring system and time series database designed for cloud-native environments. It serves developers and operators overseeing applications, systems, and services by instrumenting, collecting, storing, and querying metrics for alerting and visualization.
Key Features
For modern cloud-native stacks, Prometheus helps you instrument, collect, and query metrics across distributed services. The self-contained architecture (with local storage) makes it practical for Kubernetes-heavy environments:
Dimensional data model
Time series are identified by a metric name and a set of key-value pairs, enabling flexible querying and aggregation.
Powerful queries
The PromQL query language allows you to query, correlate, and transform time series data for visualizations, alerts, and more.
Precise alerting
Alerting rules are based on PromQL and leverage the dimensional data model; a separate Alertmanager component handles notifications and silencing.
Simple operation
Prometheus servers operate independently and rely on local storage; developed in Go, the statically linked binaries are easy to deploy across environments.
Summary
Best for DevOps teams, SREs, and platform teams monitoring Kubernetes workloads, on-prem infrastructure, and multi-cluster deployments.
