Facts

What it does: Prometheus is an open-source systems monitoring and alerting toolkit that collects and stores metrics as time series.prometheus.io · 30 Sept 2026
Data model: Time series are identified by a metric name and key-value labels, and PromQL provides a flexible query language for querying them.prometheus.io · 30 Sept 2026
Collection: Prometheus collects time series by pulling over HTTP, supports pushing through an intermediary gateway, and discovers targets through service discovery or static configuration.prometheus.io · 30 Sept 2026
Architecture: The main Prometheus server runs as a standalone monolithic binary without external dependencies.prometheus.io · 30 Sept 2026
Integrations: The ecosystem includes client libraries, exporters, Pushgateway, and Alertmanager; integrations also include Grafana for visualization and webhook-based alert notifications.prometheus.io · 30 Sept 2026
Deployment: Official components have precompiled binaries and Docker images, and the Prometheus download page lists Windows, macOS, and Linux builds.prometheus.io · 30 Sept 2026
Security: Prometheus and most exporters support TLS, including client certificate authentication, and HTTP Basic Authentication is also supported.prometheus.io · 30 Sept 2026
Security guidance: The project advises against exposing Prometheus component HTTP endpoints to publicly accessible networks unless appropriate protective measures are in place.prometheus.io · 30 Sept 2026
Reliability: Prometheus servers are autonomous and do not depend on network storage or other remote services, which the project says helps make them useful during outages.prometheus.io · 30 Sept 2026
Notable limitation: Prometheus is not recommended for use cases requiring 100% accurate data, such as per-request billing.prometheus.io · 30 Sept 2026
Support: The project offers community support through channels including Slack, mailing lists, and a Discourse forum, and lists independent commercial support providers separately.prometheus.io · 30 Sept 2026
Maintenance: Prometheus is maintained by volunteers, and security fixes are handled on a best-effort basis, with a stated aim to release fixes within seven days for several core projects.prometheus.io · 30 Sept 2026
