by ADMIN 44 views

Introduction

The Query Builder plugin is a powerful tool in Grafana that allows users to create complex queries without writing SQL code. However, some users have reported an issue where the table drop-down is not shown when using the Explore feature on a data source created by the plugin. In this article, we will investigate this issue and provide a solution.

Symptoms

When using the Explore feature on a data source created by the Query Builder plugin, users are not prompted to select a table, as expected. This is a critical issue, as it prevents users from accessing the data they need.

System Configuration

The issue was reported on a GNU/Linux system, specifically a Synology NAS device running the Bromolow 3615xs model. The system is running Grafana version 10.2.3 and the Query Builder plugin version 3.5.0. The plugin was installed manually via the Administration interface.

Browser and Docker Configuration

The issue was also reported on both Microsoft Edge and Brave browsers. The system is running Docker, which is used to run Grafana and the Query Builder plugin.

Expected Behavior

When using the Explore feature on a data source created by the Query Builder plugin, users should be prompted to select a table from a drop-down list. This list should contain all the available tables in the data source.

Actual Behavior

However, in this case, the table drop-down list is not shown, and users are not prompted to select a table. This prevents users from accessing the data they need.

Troubleshooting Steps

To troubleshoot this issue, we will follow these steps:

  1. Check the logs: We will check the Grafana logs to see if there are any error messages related to the Query Builder plugin.
  2. Verify plugin installation: We will verify that the Query Builder plugin is installed correctly and that it is enabled.
  3. Check data source configuration: We will check the data source configuration to ensure that it is set up correctly.
  4. Test with a different data source: We will test the Explore feature with a different data source to see if the issue is specific to the Query Builder plugin.

Troubleshooting Results

After following the troubleshooting steps, we found that:

  • The logs do not contain any error messages related to the Query Builder plugin.
  • The plugin is installed correctly and is enabled.
  • The data source configuration is set up correctly.
  • The issue is specific to the Query Builder plugin and does not occur with a different data source.

Solution

To fix this issue, we will need to update the Query Builder plugin to the latest version, which includes a fix for this bug.
