| description.long | M3 is a metrics platform consisting of a distributed time-series database, query engine, and ingestion system designed to handle massive metric volumes efficiently. It provides Prometheus and Graphite compatibility while optimizing for performance and cost efficiency through purpose-built storage and querying components. | A systems monitoring platform that collects metrics from configured targets at regular intervals, evaluates alert rules using PromQL, and triggers notifications. It uses a dimensional data model with key-value labels for flexible metric analysis and dashboarding. |
