What problem it solves

Systems and services need to be monitored by collecting metrics at regular intervals, evaluating rule expressions, presenting results, and alerting when specified conditions occur. Prometheus provides this monitoring workflow with a dimensional data model, flexible querying, and both pull-based and gateway-mediated time-series collection.

Key features

• Multi-dimensional time-series data — Time series are defined by a metric name and a set of key/value dimensions, allowing monitoring data to be queried across its dimensions.

  Source: README

• PromQL querying — PromQL provides a flexible query language for working with the dimensional time-series model.

  Source: README

• Pull and push collection — Time-series collection uses an HTTP pull model, while batch jobs can push time series through an intermediary gateway.

  Source: README

• Service discovery — Targets can be found through service discovery or defined through static configuration. The project also includes configurable service discovery plugins.

• Rules, alerts, dashboards, and federation — Prometheus evaluates rules, can trigger alerts, supports graphing and dashboarding, and provides hierarchical and horizontal federation.

Quick start

Copied verbatim from the project's README.

docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus

go install github.com/prometheus/prometheus/cmd/...
prometheus --config.file=your_config.yml

make build
./prometheus --config.file=your_config.yml

Who it may suit

This may suit operators who need to monitor systems and services, or developers building applications that expose and consume time-series metrics. It may also suit contributors working on its monitoring, querying, storage, discovery, or alerting components.

Topics to discuss

• How are teams using PromQL to make multi-dimensional monitoring data easier to explore?

• Which operational challenges are most important to address in future releases?

• How can the community improve documentation and examples for installation, configuration, and alerting?
