Grafana
Grafana is an open-source analytics and interactive visualization web application for monitoring and observability. It allows users to query, visualize, alert on, and understand metrics from various data sources like time-series databases, logs, and distributed traces. It is widely used for creating dashboards that display real-time data from systems, applications, and infrastructure.
Developers should learn Grafana when building or maintaining systems that require monitoring, such as web applications, microservices, or cloud infrastructure, to gain insights into performance, troubleshoot issues, and set up alerts. It is particularly useful in DevOps and SRE roles for visualizing metrics from tools like Prometheus, InfluxDB, or Elasticsearch, enabling proactive management of system health and resource utilization.
