Grafana is an open-source data visualization and monitoring tool. It provides a flexible and customizable platform for creating dashboards, graphs, and charts to visualize and analyze data from various sources. Grafana offers support for a wide range of data sources including databases, cloud services, time series databases, and many more. With Grafana, users can connect to their desired data source, query the data using a query language such as SQL or PromQL (Prometheus Query Language), and then create visually appealing dashboards to display the data in real-time. It offers a drag-and-drop interface, allowing users to easily design their dashboards with various panels like graphs, tables, gauges, and alert lists. One of the key features of Grafana is its ability to support time series data analysis. It can handle large volumes of time-based data that are commonly used for monitoring purposes in industries such as IT operations, DevOps, IoT (Internet of Things), and industrial automation. Grafana allows users to plot time series data on graphs with different visualization options such as line charts, bar charts, heatmaps, and more. Grafana also supports alerting capabilities where users can define thresholds or conditions based on their data metrics. When these conditions are met, alerts can be triggered via email notifications or integrated with other notification channels like Slack or PagerDuty. Moreover, Grafana has a plugin system that offers extensive customization options. Users can extend the functionality of Grafana by installing plugins developed by the community or building their own plugins. # What is the relation between Grafana and Prometheus [[Grafana]] and [[Prometheus]] are two popular open-source tools in the field of monitoring and observability. Prometheus is a time-series database and monitoring system that collects metrics from various sources, such as applications, systems, and services. It uses a pull model to scrape metrics from targets at regular intervals. Prometheus provides powerful querying capabilities, alerting functionality, and a simple yet flexible data model. On the other hand, Grafana is a data visualization and dashboarding tool that allows users to create interactive visualizations based on data from various sources. It supports multiple data sources, including Prometheus. Grafana provides a user-friendly interface to create customized dashboards with real-time or historical data from Prometheus. In summary, Prometheus collects and stores metrics while Grafana provides a platform to visualize and analyze these metrics using customizable dashboards. Together, they form a powerful combination for monitoring and analyzing the performance of systems and applications. Grafana and Prometheus are two popular open-source tools used for monitoring and visualizing system metrics and time-series data. Prometheus is a monitoring and alerting tool that collects metrics from various systems, including servers, applications, databases, and more. It has its own query language called PromQL to analyze and retrieve data from the collected metrics. Prometheus stores the collected data in a time-series database. On the other hand, Grafana is a visualization tool that provides a flexible and customizable dashboard for displaying metrics and time-series data. It supports various data sources, including Prometheus. Grafana can connect to Prometheus to fetch the collected data and create interactive visualizations, charts, graphs, and alerts based on that data. In summary, Prometheus collects metrics from various sources while Grafana provides a user-friendly interface to visualize those metrics collected by Prometheus. # Grafana integrated with CIllium and eBPF Grafana can be integrated with [[Cilium]] or [[eBPF]] in several ways to provide monitoring and visualization capabilities. Here are a few common integration methods: 1. Prometheus Integration: Cilium and eBPF can export metrics to [[Prometheus]], which is a popular open-source monitoring system. [[Literature/PKM/Tools/Open Source/Grafana]] can then be configured to pull data from Prometheus and display it in customizable dashboards. This integration allows you to visualize various metrics related to network connectivity, security policies, load balancing, and more. 2. Grafana Dashboards: Grafana provides pre-built dashboards for Cilium that can be imported and customized according to your specific requirements. These dashboards leverage the metrics exported by Cilium or eBPF and offer visualizations such as graphs, charts, tables, and alerts. 3. Data Source Plugins: Grafana supports various data source plugins that can directly connect to Cilium or eBPF APIs. These plugins allow Grafana to fetch real-time data from the respective sources and visualize it in the form of dynamic dashboards. 4. Alerting: Grafana has built-in alerting capabilities that can be configured based on specific thresholds or conditions. By integrating Cilium or eBPF with Grafana's alerting system, you can receive notifications or trigger actions based on predefined rules related to network performance, security events, or other metrics. Overall, the integration of Grafana with Cilium or eBPF enables you to gain insights into network behavior and security events through visually appealing dashboards and real-time monitoring capabilities. # Conclusion Overall, Grafana is widely used for monitoring infrastructure performance metrics, visualizing log analytics data, analyzing time series data from IoT devices, creating executive dashboards for business intelligence purposes, and much more. # References ```dataview Table title as Title, authors as Authors where contains(subject, "Grafana") ```
