# View Gcore Managed Logging data in Grafana with OpenSearch plugin

The [OpenSearch Grafana Data Source](https://grafana.com/grafana/plugins/grafana-opensearch-datasource/?tab=overview) plugin integrates logs from OpenSearch Dashboards into Grafana, providing a consolidated view of all metrics in one place alongside Grafana's advanced alerting and visualization features. It also enables granular access control over who can view and manage logs, protecting sensitive information.

## Step 1. Set up Managed Logging in the Gcore Customer Portal

Configure Managed Logging in the Gcore Customer Portal to obtain the OpenSearch API endpoint URL and credentials needed in later steps. For details, see [Configure Managed Logging and view logs](/cloud/logging-as-a-service/configure-logging-and-view-your-logs).

## Step 2. Install OpenSearch plugin in Grafana

If the plugin is already installed, skip to **Step 3**.

To install the plugin:

1\. In Grafana, navigate to the **Administration** section and click **Plugins**.

2\. Search for the OpenSearch plugin. In the **State** dropdown, select **All** to ensure the plugin appears in the results.

3\. Click **Install**.

<Info>
  After selecting **Basic auth**, the following error may appear: "OpenSearch error: no permissions for \[indices:admin/mappings/get] and User \[name=test2, backend\_roles=\[], requestedTenant=null]". This is a mapping-fetch error that does not affect data retrieval or plugin functionality — ignore it and continue.
