## AI overview

SoundCloud describes why it developed Prometheus for monitoring a large microservice estate. The system combines a multidimensional metrics model, local storage, decentralized collection, querying, alerting, and dashboarding.

## Source excerpt

In previous blog posts, we discussed how SoundCloud has been moving towards a microservice architecture. Soon we had hundreds of services, with many thousand instances running and changing at the same time. With our existing monitoring set-up, mostly based on StatsD and Graphite, we ran into a number of serious limitations. What we really needed was a system with the following features: A multi-dimensional data model, so that data can be sliced and diced at will, along dimensions like instance, service, endpoint, and method. Operational simplicity, so that you can spin up a monitoring server where and when you want, even on your local workstation, without setting up a distributed storage backend or reconfiguring the world. Scalable data collection and decentralized architecture, so that you can reliably monitor the many instances of your services, and independent teams can set up independent monitoring servers. Finally, a powerful query language that leverages the data model for meaningful alerting (including easy silencing) and graphing (for dashboards and for ad-hoc exploration). All of these features existed in various systems. However, we could not identify a system that combined them all until a colleague started an ambitious pet project in 2012 that aimed to do so. Shortly thereafter, we decided to develop it into SoundCloud's monitoring system: Prometheus was born.
