Prometheus 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.
Prometheus is designed for reliability, to be the system you go to during an outage to allow you to quickly diagnose problems. Each Prometheus server is standalone, not depending on network storage or other remote services. You can rely on it when other parts of your infrastructure are broken, and you do not need to setup extensive infrastructure to use it.
This is free and open source software.
Key Features
- Simple operation – each server is independent for reliability.
- 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. When you send a query request to Prometheus, it can be an instant query, evaluated at one point in time, or a range query at equally-spaced steps between a start and an end time. PromQL works exactly the same in each cases; the range query is just like an instant query run multiple times at different timestamps.
- Grafana supports querying Prometheus.
- 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.
- Includes a local on-disk time series database, but also optionally integrates with remote storage systems.
- Preice alerting – alerts are defined on the software’s flexible PromQL.
