Prometheus

Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts when specified conditions are observed.

Features

• A multi-dimensional data model (time series defined by metric name and set of key/value dimensions)
• PromQL, a powerful and flexible query language to leverage this dimensionality
• No dependency on distributed storage; single server nodes are autonomous
• An HTTP pull model for time series collection
• Pushing time series is supported via an intermediary gateway for batch jobs
• Targets are discovered via service discovery or static configuration
• Multiple modes of graphing and dashboarding support
• Support for hierarchical and horizontal federation
