Grafana enables you to query, visualize, alert on, and explore your metrics, logs, and traces wherever they are stored. Grafana OSS provides you with tools to turn your time-series database (TSDB) data into insightful graphs and visualizations.

I’ve blogged extensively on different timeseries projects using grafana on the hashbang blog
