Prometheus is a Cloud Native Computing Foundation graduated open source systems monitoring and alerting toolkit. A Prometheus server scrapes metrics over HTTP from instrumented targets, stores them in an embedded time series database, and lets operators query, alert, and aggregate them with the PromQL query language. The project pairs the Prometheus server with Alertmanager for alert routing and silencing, official client libraries for Go, Java, Python, Ruby, and Rust, and a large ecosystem of exporters (node, blackbox, snmp, statsd, jmx, mysqld, cloudwatch, consul, graphite, memcached, pushgateway, etc.) for pulling metrics out of existing systems. Prometheus also drives the OpenMetrics exposition format and an experimental Remote Write 2.0 protocol for shipping samples to long-term storage backends.
