Grafana is a tool for working with monitoring metrics. With it, you can get statistics in a user-friendly visual format and track CDN.
We have released a plugin that will allow users to get Gcore CDN statistics in Grafana as easily as possible. Below, we will tell you what CDN monitoring capabilities Grafana comes with, how to connect the plugin and streamline statistics operations.
Grafana at a glance
Grafana is an open-source monitoring tool designed to visualize and work with statistical data. It is chiefly intended to transform metrics into a user- and human-friendly visual form.
Grafana does not collect or store anything. But you can connect the plugin to the system where statistics is accumulated in the form of cold, hard numbers and it will convert such data into a convenient graph, a simple table, or a diagram.
Metrics can be sourced from virtually any data storage system. Statistics can be aggregated from different sources in one place.
Grafana has dozens of visualization methods. Data can be graphed, diagrammed, distributed, or presented in absolute values. Data can be grouped and aggregated into interactive dashboards.
You can configure variables and use them to switch between the data displayed on the dashboard, filter metrics, change the period of time for which statistics is displayed, and so on. Grafana has everything to work with statistics and efficiently analyze data.
How Grafana helps monitor CDN
Statistics, with which you can check the CDN efficiency, comes from your provider. But Grafana will help you âwrap upâ the figures in user-friendly graphs and group information the way you want it.
Grafana will come in handy if you use multi-CDN. The tool will allow you to aggregate statistics from different providers in one place and determine how to best distribute traffic between different content delivery networks.
Besides, Grafana has many useful features to work with CDN statistics. For example, if you receive data on the traffic consumed, you can configure notifications and Grafana will alert you every time traffic consumption hits a certain figure. That way, you can control consumption and avoid overages.
How to get Gcore CDN statistics via Grafana
We provide statistics on:
- total traffic volume
- cached traffic volume
- traffic from CDN servers
- traffic from origin shielding
- origin traffic
- number of requests
- number of 2xx, 3xx, 4xx, and 5xx responses
In Grafana, you can group these metrics by the following parameters:
- clients
- CDN resources
- regions
- countries
- data centers
For example, you can check how much traffic comes from this or that country and see how the load is distributed.
In the early days, you could get Gcore CDN statistics in Grafana via API only. And you had to make complex adjustments, which took time.
And now you can connect our CDN to Grafana and get necessary metrics virtually in a few clicks with the plugin that we released specifically to make your statistics operations easier.

How to add and configure statistics dashboard
1. Add a new dashboard. In the side menu, click + and select Dashboard.
2. Add and configure a panel. Click Add an empty panel. In the new window, select cdn-stats as a data source:
Select metrics, granularity and groupings you need. You can select several groupings.
3. Add and configure a variable. With the variable, you can filter data in the graph. You can add several variables for different parameters.
We will tell you how to add and configure a variable to filter resources. The same will apply to other variables.
In order to add a variable, click the Settings icon at the top:
Select Variables and click Add variable.
Then, you have to configure the variable:
- Enter its name.
- Select the value: resourceID or client.
- Should you so wish, you can specify the order, in which elements are sorted.
- Optionally, you can specify the order, in which elements are highlighted: Multi-valueâselects several values at a time, Include All optionâincludes the All value.
- Click Update.
4. Bind the variable to the dashboard.
Go back to the dashboard:
And enter the variable name in the resource filter (Filters section, Resources field). Type in $ before the name.
That done, you can decide the data of which resources you want to display in the graph.
5. Save the dashboard. In order to save the dashboard, click Save in the top right corner.
Your dashboard is now configured and ready for use.
