No data showing up on Grafana dashboards

This page shows you how to visualize your data again when it does not display on your Grafana dashboards, using the SyncGrafanaDataSources endpoint of the Cockpit Global API or the Scaleway CLI.

Important

The Cockpit Global API contains deprecated information that is being updated, you should not use it for any other purpose than the one described on this page.

Before you start

To complete the actions presented below, you must have:

Problem

  • Many Cockpit users often encounter issues with Grafana data sources not synchronizing properly, leading to missing data on dashboards when data should be available.

    When users open their Grafana dashboards, they see a No data message along with an error banner stating: Failed to upgrade legacy queries datasource was not found.

  • Your Cockpit is unavailable.

  • You cannot view your logs and/or metrics in Grafana.

  • Your Cockpit data sources are not configured.

  • You cannot view your dashboards in Grafana.

Cause

These issues often occur due to synchronization failures between Cockpit and Grafana, preventing dashboards from displaying the latest logs and metrics as expected.

Tip

Sometimes, what looks like a synchronization issue may simply be due to the asynchronous nature of the synchronization between Grafana and your data sources. If you have logged into Grafana while the synchronization was still in progress, your data might not appear right away.

Try refreshing your browser page first. If the problem persists, the synchronization may have failed but you can trigger a new one manually using the procedure below.

Solution

Using the Scaleway API

Open a terminal and run the following command to trigger the synchronization of your data sources:

curl -X POST \
-H "X-Auth-Token: $SCW_SECRET_KEY" \
-H "Content-Type: application/json" \
-d '{"project_id":"$SCALEWAY_PROJECT_ID"}' \
"https://api.scaleway.com/cockpit/v1/grafana/sync-data-sources"

Make sure that you replace $SCW_SECRET_KEY with your API secret key and $SCALEWAY_PROJECT_ID with the ID of the Scaleway Project affected by the issue.

Using the Scaleway CLI

Open a terminal and run the following command:

scw cockpit grafana sync-data-sources project-id=<PROJECT-ID>

Make sure that you replace <PROJECT-ID> with the ID of the Scaleway Project affected by the issue.
