# Reporting

You can use OpenSearch Dashboards to create PNG, PDF, and CSV reports. To create reports, you must have the correct permissions. For a summary of the predefined roles and the permissions they grant, see the [security plugin](../../security/access-control/users-roles/#predefined-roles).


## Create reports from Discovery, Visualize, or Dashboard

Quickly generate an on-demand report from the current view.

1. From the top menu bar, choose **Reporting**.
1. For dashboards or visualizations, choose **Download PDF** or **Download PNG**. From the Discover page, choose **Download CSV**.

   Reports generate asynchronously in the background and might take a few minutes, depending on the size of the report. A notification appears when your report is ready to download.

1. To create a schedule-based report, choose **Create report definition**. Then proceed to [Create reports using a definition](#create-reports-using-a-definition). This option pre-fills many of the fields for you based on the visualization, dashboard, or data you were viewing.


## Create reports using a definition

Definitions let you generate reports on a periodic schedule.

1. From the navigation panel, choose **Reporting**.
1. Choose **Create**.
1. Under **Report settings**, enter a name and optional description for your report.
1. Choose the **Report Source** (i.e. the page from which the report is generated). You can generate reports from the **Dashboard**, **Visualize**, or **Discover** pages.
1. Select your dashboard, visualization, or saved search. Then choose a time range for the report.
1. Choose an appropriate file format for the report.
1. (Optional) Add a header or footer to the report. Headers and footers are only available for dashboard or visualization reports.
1. Under **Report trigger**, choose either **On-demand** or **Schedule**.

   For scheduled reports, select either **Recurring** or **Cron based**. You can receive reports daily or at some other time interval. Cron expressions give you even more flexiblity. See [Cron expression reference](../../alerting/cron/) for more information.

1. Choose **Create**.

## Troubleshooting

### Chromium fails to launch with OpenSearch Dashboards

While creating a report for dashboards or visualizations, you might see a the following error:

![OpenSearch Dashboards reporting pop-up error message](../../images/reporting-error.png)

This problem can occur for two reasons:

- You don't have the correct version of `headless-chrome` to match the operating system on which OpenSearch Dashboards is running. Download the correct version [here](https://github.com/opensearch-project/dashboards-reports/releases/tag/chromium-1.12.0.0).

- You're missing additional dependencies. Install the required dependencies for your operating system from the [additional libraries](https://github.com/opensearch-project/dashboards-reports/blob/main/dashboards-reports/rendering-engine/headless-chrome/README.md#additional-libaries) section.
