Grafana is like a canvas where you can paint a picture of your data. It's a tool that helps you create interactive and customizable dashboards to visualize and analyze your metrics and logs. Whether you want to track the performance of your application, monitor server health, or analyze user behavior, Grafana makes it easy to turn your data into meaningful visualizations.
Let's say you have a time-series database like Prometheus that collects metrics from your infrastructure. With Grafana, you can connect to Prometheus and build a dashboard that displays real-time CPU utilization, memory usage, and network traffic for example.
Grafana also supports logging data sources. You can create a dashboard that shows the error rate of your application alongside the corresponding error logs, making it easier to troubleshoot issues and understand the context in which they occurred.
