• Group data: Group data for better organization.
• Variables: Use variables for flexible queries.

What is Grafana Data Source Backend Plugin?

A Backend plugin is a type of data-source plugin that runs on the server. You will need access to the Edgecenter API from the Grafana server to properly interact with the plugin.

Installation

Prerequisites

• Grafana >=10.4.0
• EdgeCenter API credentials

Getting Started

To begin using this plugin, download it and place it in the grafana/plugins directory.

Note: This plugin is currently unsigned, so Grafana will block it from loading by default. To enable it, you need to explicitly allow unsigned plugins. If you're using Grafana with containers, you can do this by adding the following environment variable:

-e "GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=edgecenter-cdn-datasource"

This will allow Grafana to load the plugin and start using it.

Configuration

To configure the data source, update the Grafana datasources.yaml file:

apiVersion: 1

datasources:
  - name: 'cdn-datasource'
    type: 'edgecenter-cdn-datasource'
    access: proxy
    isDefault: false
    orgId: 1
    version: 1
    editable: true
    jsonData:
      apiUrl: 'https://api.edgecenter.ru'
    secureJsonData:
      apiKey: '####'

Alternatively, use the Grafana API to add the data source:

curl -XPOST -i http://admin:$ADMIN_PASSWORD@localhost:3000/api/datasources \
     --data-binary '{"name": "cdn-datasource","type": "edgecenter-cdn-datasource", \
     "orgId": 1,"access":"proxy", "jsonData":{"apiUrl": "https://api.edgecenter.ru"}, \
     "secureJsonData":{"apiKey": "####"}}' -H "Content-Type: application/json"

Docker run

This command runs a Grafana container and installs a plugin. Grafana will be available on port 3000.

docker run -d \
    -p 3000:3000 \
    --name=grafana \
    -e "GF_INSTALL_PLUGINS=https://github.com/Edge-Center/grafana-cdn-datasource/releases/download/v1.0.1/edgecenter-cdn-datasource-1.0.1.zip;edgecenter-cdn-datasource" \
    -e "GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=edgecenter-cdn-datasource" \
     grafana/grafana-enterprise:10.4.12

Usage

• Create a new dashboard in Grafana.
• Add a panel and select CDN Datasource as the data source.
• Configure the query parameters to retrieve specific CDN metrics.
• Apply visualizations and filters as needed.
