Create custom logs

Change configuration for the Control Plane, customize Platform Services

There are several use cases for customized log collection. The central logging stack is deployed within your environment, as with any other application, streamlining the customization process.

Customizing OpenSearch logging

The version of OpenSearch, the EC2 host size, and the control plane configuration are all deployed based on the configuration you define in the Service Description. Use this procedure to customize the Service Description according to your requirements.

You must make Service Description changes before you enable central logging. If central logging is enabled, you cannot edit the description using the Service Description window.

  1. In the DuploCloud Portal, navigate to Administrator -> System Settings.

  2. In the Service Description tab, in the Name column, select duplo_svd_logging_opensearch. The Service Description window displays.

  3. Edit the YAML in the Service Description window as needed.

  4. Click Update when the configuration is complete to close the window and save your changes.

Updating the Control Plane by editing the Service Description

You can update the Control Plane configuration by editing the Service Description. If the control plane is already deployed using the Service Description specification, then updating the description is similar to making a change to any application.

Note that Control Plane Components are deployed in the DuploCloud Default Tenant. Using the Default Tenant, you can change instance size, Docker images, and more.

Updating the OpenSearch log retention period

You can update the log retention period using the OpenSearch native dashboard by completing the following steps.

  1. From the DuploCloud portal, navigate to Administrator -> Observability -> Logging.

  2. Click Open New Tab to access the OpenSearch dashboard.

  3. Navigate to Pancake -> Index management -> State management policies.

  4. Edit the FileBeat YAML file and update the retention period.

For more information see the OpenSearch documentation.

The new retention period settings will only apply to logs generated after the retention period was updated. Older logs will still be deleted according to the previous retention period settings.

Customizing Elastic Filebeat logging

You can modify Elastic Filebeat logging configurations, including mounting folders other than /var/lib/docker for writing logs to folders other than stdout.

You need to customize the log collection before enabling logging for a Tenant.

If logging is enabled, you can update the Filebeat configuration for each tenant by editing the Filebeat Service Description (see the procedure in Defining Control Plane Configuration).

Alternately, delete the Filebeat collector from the Tenant and the platform automatically redeploys based on the newest configuration.

  1. In the DuploCloud Portal, navigate to Administrator -> System Settings.

  2. Select the Platform Services tab.

  3. Click the Edit Platform Services button. The Platform Services window displays. Select the appropriate Filebeat service. For native container management, select filebeat; for Kubernetes container management, select filebeat-k8s.

  4. Edit the YAML in the Platform Services window as needed.

  5. Click Update to close the window and save your changes.

Third-Party Logging Tools

With DuploCloud, you have the choice to deploy third-party tools such as Datadog, Sumo Logic, and so on. To do this, deploy Docker containers that act as collectors and agents for these tools. Deploy and use these third-party app containers as you would any other container in DuploCloud.
