Why should I use StatsHouse?

StatsHouse is used in production at big scale
StatsHouse is the main monitoring system of vk.com. As of November 2023, main StatsHouse cluster is receiving 1.2 billion metrics per second from 22000 servers and stores 5 years of data.

StatsHouse provides high resolution, low latency data
With default metric resolution of 1 second and latency of 5 seconds, StatsHouse makes it easy to observe things happening in great detail immediately as they are happening.

StatsHouse provides long-term metrics storage
StatsHouse automatically downsamples high-resolution data to 1 minute and 1 hour resolutions with automatic TTL. High-resolution data is stored for 2 days, minute-resolution data is stored for a month, and hour-resolution data is stored indefinitely.

StatsHouse is easy to operate
StatsHouse automatically works around network unavailability and individual machine failure. Most StatsHouse components are quasi-stateless. Main stateful component is a ClickHouse cluster which StatsHouse uses internally as a primary data store.

StatsHouse is almost impossible to overload
StatsHouse uses explicitly configured per-second budgets for network and disk usage, and automatically samples metrics which use more than their fair share of the budget.

StatsHouse has a built-in UI
Built-in UI allow to interactively dig into metrics without using any query language. It also has a simple dashboard system. For more advanced use cases, StatsHouse provides a Grafana data source plugin as well.
