Grafana dashboards are powerful open-source analytical and visualization tools that consist of multiple individual panels arranged in a grid, interacting with configured data sources such as InfluxDB, Telegraf, AWS CloudWatch, and others. They enable users to gain insights into time-series data, allowing for efficient and organized data analysis through queries, informative visualizations, and alerts. With Grafana dashboards, users can share their creations with other team members, explore the data together, and customize the dashboards using open-source templates and variables, making it easy to set up a dynamic and interactive dashboard. The integration of Grafana with InfluxDB provides customized visual presentations of key metrics and events with fast rendering, even over large time spans, making it an ideal choice for real-time analytics based on time series data.
