Graphite
Graphite is an open-source monitoring and graphing tool designed for storing and visualizing time-series data, such as system metrics and application performance. It consists of three main components: Carbon (a daemon for receiving metrics), Whisper (a database for storing time-series data), and Graphite-web (a web interface for creating graphs and dashboards). It is widely used in DevOps and IT operations for real-time monitoring and trend analysis.
Developers should learn Graphite when they need to monitor infrastructure, applications, or services in production environments, especially for tracking metrics like CPU usage, request latency, or error rates. It is particularly useful in DevOps workflows for performance tuning, capacity planning, and alerting, as it integrates well with tools like StatsD and Grafana for enhanced visualization and automation.
