Grafanalabs

Grafana is the world's most popular open-source platform for monitoring and observability. It allows you to query, visualize, alert on, and understand your metrics no matter where they are stored. Unlike other tools that force you to move your data into their database, Grafana connects directly to your existing data sources (like Prometheus, AWS CloudWatch, SQL, InfluxDB, etc.). It acts as a 'Single Pane of Glass,' meaning you can see data from 50 different tools on one beautiful, customizable dashboard. If a server goes down or a website gets slow, Grafana is the tool that shows you the red spike and sends the alert.
