trickster - Trickster - Open Source Dashboard Accelerator for Prometheus

  •    Go

Trickster is a reverse proxy cache for the Prometheus HTTP APIv1 that dramatically accelerates dashboard rendering times for any series queried from Prometheus. Most dashboards request the entire time range of data from the time series database, every time a dashboard loads or reloads. Trickster's Delta Proxy inspects the time range of a client query to determine what data points are already cached, and requests from Prometheus only the data points still needed to service the client request. This results in dramatically faster chart load times for everyone, since Prometheus is queried only for tiny incremental changes on each dashboard load, rather than several hundred data points of duplicative data.
