To import custom dashboards to Grafana using Helm, you can follow these steps:
- First, you need to have Helm installed on your local machine or in your Kubernetes cluster.
- Create a new folder on your local machine, and navigate to that folder using the command line.
- Create a new Helm chart using the command helm create . This will create a new directory with the chart template files.
- Navigate inside the newly created chart folder using the command cd .
- Open the values.yaml file in the chart folder and modify it to include the necessary configurations. This can include things like ingress settings, service type, and any other required configurations.
- Create a new folder inside the chart folder called dashboards, where you will store your custom dashboard files. You can have multiple dashboard files inside this folder.
- Copy your custom dashboard JSON files inside the dashboards folder.
- Open the templates folder in the chart directory and create a new file called dashboards.yaml. This file will define the configuration to import the custom dashboards.
- Inside dashboards.yaml, add the following code block to define a ConfigMap that will store the custom dashboard JSON files:
1 2 3 4 5 6 7 8 9 10 11 |
apiVersion: v1 kind: ConfigMap metadata: name: {{ include "<chart-name>.fullname" . }}-dashboards labels: {{- include "<chart-name>.labels" . | nindent 4 }} data: {{- range $path, $content := .Files.Glob "dashboards/*" }} {{ $name := $path | base | trimSuffix ".json" }} {{ $content | indent 2 | quote }}: |- {{ $name | quote }}{{ end }} |
- Save the dashboards.yaml file.
- Now, open the deployment.yaml file in the template folder and ensure that the following lines are present:
1 2 3 |
env: - name: GF_PATHS_PROVISIONING value: "/etc/grafana/provisioning" |
- Save the deployment.yaml file.
- Finally, you can install the chart using the command helm install ./.
This will install Grafana along with the custom dashboards defined in the dashboards folder. The dashboards will be automatically imported into Grafana upon installation.

Do custom dashboards need to be in a specific format for Helm to import them?
Yes, Helm requires custom dashboards to be in a specific format for importing them. Helm uses the Grafana Dashboard JSON format for managing dashboards. The dashboard JSON file should follow the structure and format defined by Grafana to ensure successful importing through Helm. This format includes specifying panels, visualization types, queries, and other properties associated with the dashboard.
Can you rollback to a previous version of a custom dashboard if there are issues with the import?
Yes, you can rollback to a previous version of a custom dashboard if there are issues with the import. The rollback process may vary depending on the specific dashboard platform or tool you are using. However, in general, the steps involved in rolling back to a previous version are as follows:
- Access the dashboard management interface or settings for your dashboard platform.
- Look for an option to manage versions or backups of your dashboard.
- Select the appropriate version or backup of the dashboard that you want to restore.
- Confirm the rollback action and proceed with the restoration.
- After the rollback is complete, review and verify that the issues with the import have been resolved.
Remember to save a backup of your custom dashboards regularly to ensure you have previous versions available for rollback if needed.
How do you ensure the custom dashboards are successfully imported and accessible in Grafana?
To ensure that custom dashboards are successfully imported and accessible in Grafana, you can follow these steps:
- Export the dashboard: Go to the Grafana dashboard that you want to export, click on the settings icon (gear icon), and select "Export". This will generate a JSON file containing the dashboard configuration.
- Move the JSON file to the Grafana server: Copy the exported JSON file to the server where Grafana is installed. You can use any method like FTP, SCP, or any file transfer mechanism.
- Import the dashboard: Log in to the Grafana web interface and go to the home page. Click on the "+" icon on the left sidebar and select "Import". Choose the JSON file you copied in the previous step and click on "Upload".
- Configure the data source: During the import process, Grafana will prompt you to select a data source for the imported dashboard. Select the appropriate data source that matches the original dashboard configuration.
- Verify and access the dashboard: After importing, Grafana will show a preview of the imported dashboard. Ensure that all panels, queries, and visualizations are correctly imported and displayed. If everything looks fine, click on "Import" to save the dashboard. The imported dashboard will now be accessible through the Grafana home page.
- Check access permissions: Ensure that the user or user group that needs to access the imported dashboard has the necessary permissions. You can manage users and their access rights in the Grafana settings.
By following these steps, you can successfully import and make custom dashboards accessible in Grafana.
Is it possible to customize or modify the imported dashboards after importing them using Helm?
Yes, it is possible to customize or modify the imported dashboards after importing them using Helm. After importing the dashboards, you can modify the YAML files that define the dashboards and make necessary changes as per your requirements.
You can edit the YAML files directly or use a text editor to modify them. Once you have made the desired changes, you can apply the changes by deploying the updated Helm charts using the Helm CLI.
It is important to note that any changes made to the imported dashboards should be managed carefully, keeping in mind the compatibility with the monitoring tool and any future updates or modifications that may be applied to the dashboards.
Is it possible to schedule automatic imports of custom dashboards with Helm at specific intervals?
No, Helm does not provide a native feature to schedule automatic imports of custom dashboards at specific intervals. Helm is primarily used for managing Kubernetes applications and deploying resources to the cluster.
If you want to schedule automatic imports of custom dashboards, you may consider using other tools or frameworks, such as CronJobs (Kubernetes native), Jenkins, or other CI/CD pipelines, to execute the import operation periodically. These tools can be used to trigger a script or API call that imports the custom dashboards into your dashboarding system, such as Grafana.
What other tools or utilities can be used alongside Helm for managing custom dashboards?
There are several tools and utilities that can be used alongside Helm for managing custom dashboards. Some popular options include:
- Grafana: Grafana is a widely used open-source monitoring and visualization tool that integrates well with Helm. It allows you to create rich dashboards with various data sources, including Helm, and offers a range of visualization options.
- Kibana: Kibana is part of the Elastic Stack and is primarily used for analyzing and visualizing logs and metrics. It can be integrated with Helm to create customized dashboards that provide insights into your application's logs and metrics.
- Prometheus: Prometheus is an open-source monitoring and alerting system that works well with Helm. It collects metrics from your applications and provides a powerful query language to create custom dashboards that show real-time performance data.
- Datadog: Datadog is a popular monitoring and analytics platform that can be integrated with Helm to create custom dashboards. It offers a wide range of visualization options and allows you to aggregate and analyze metrics from various sources.
- Splunk: Splunk is a powerful log aggregation and analysis platform that can be used alongside Helm. It provides rich visualization capabilities, allowing you to create custom dashboards that display logs and monitor application performance.
- InfluxDB + Chronograf: InfluxDB is a time-series database and Chronograf is its user interface. Together, they can be used alongside Helm to create custom dashboards for monitoring and analyzing time-series data.
These are just a few examples, and there are many other tools and utilities available that can be used alongside Helm for managing custom dashboards, depending on your specific needs and preferences.
