Grafana dashboards and plugins

Grafana is a widely used open-source visualization and monitoring tool. It supports querying Metrics from various databases and creating customizable dashboards for data visualization^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].

Dashboards

Grafana allows users to create visualizations of their data through Dashboards^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md]. These dashboards are collections of panels arranged on one or more rows.

Importing Dashboards

There are two primary methods for populating Grafana with dashboards:

  1. JSON Import: Users can import dashboard definitions using JSON files. This allows for the manual loading of pre-configured dashboard setups^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
  2. Community Templates: Users can browse and utilize dashboards shared by the community via the official Grafana website^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md]. These templates often use a numeric ID that can be entered directly into Grafana to load the configuration^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].

Dashboard Configuration

When setting up a dashboard, users must typically configure the Data Source that the dashboard will query^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md]. For example, in Kubernetes environments, dashboards often connect to a Prometheus instance to visualize cluster and application metrics^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].

Plugins

Plugins extend the functionality of Grafana by adding new data sources, visualizations, and applications^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].

Installation

Plugins can be installed using the Grafana CLI tool (grafana-cli) from within the running Grafana container^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].

Common Plugins

Several plugins are frequently utilized in Kubernetes monitoring setups:

  • Kubernetes App: An application plugin for monitoring Kubernetes clusters^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
  • Clock Panel: A visualization plugin for displaying time^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
  • Pie Chart Panel: Provides pie chart visualization options^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
  • D3 Gauge: Adds gauge-style visualizations^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
  • Discrete: A plugin supporting specific state visualization (often used for status monitoring)^[400-devops__06-Kubernetes__k8s-paas__07.Promtheus监控k8s企业级应用.md].
