Introduction

Grafana is an open-source data visualization and analytics tool that helps users explore and visualize their time-series data, making it ideal for monitoring applications, infrastructure, and services. It is often used alongside monitoring tools like Prometheus, Elasticsearch, and InfluxDB to provide interactive dashboards, charts, and graphs. Grafana is widely adopted in cloud-native and microservices environments due to its flexibility, extensive plugin ecosystem, and ease of integration with various data sources. It enables businesses to gain actionable insights from their data, promoting data-driven decision-making.

Prerequisites

• Basic understanding of monitoring and time-series data.
• Familiarity with web-based tools and dashboards.
• Knowledge of data sources like Prometheus, InfluxDB, or Elasticsearch.
• Familiarity with basic Linux commands and systems for setup.
• Understanding of cloud-native and containerized environments like Kubernetes (optional).
