> Monitor asset usage and compute costs in the reporting center dashboard. Track storage consumption, identify least-used assets for deprecation, and analyze top queries and most expensive assets across your data estate.

:::warning Who can do this?
 You must be an [admin user](https://docs.atlan.com/llms/governance/access-control/delegate-administration/llms.txt) in Atlan to view the reporting center. If [enabled by admins](https://docs.atlan.com/llms/governance/access-control/access-control-settings/llms.txt), [member users](https://docs.atlan.com/llms/governance/access-control/delegate-administration/llms.txt) can also view the [assets](https://docs.atlan.com/llms/catalog/reporting/how-to-report-on-assets/llms.txt), [glossary](https://docs.atlan.com/llms/catalog/reporting/report-on-glossaries/llms.txt), [Data Exploration](https://docs.atlan.com/llms/catalog/reporting/report-on-queries/llms.txt), and [usage and cost](https://docs.atlan.com/llms/catalog/reporting/report-on-usage-and-cost/llms.txt) dashboards.

Optimize your data estate by monitoring usage and compute costs in the reporting center dashboard. Track storage consumption, identify the most popular and most expensive assets, find least-used assets for potential deprecation, and analyze query patterns and cost breakdowns across users and asset types.

The reporting center supports [usage and cost metrics](https://docs.atlan.com/llms/catalog/usage-and-popularity/interpret-usage-metrics/llms.txt) for the following connectors:

- [Amazon Redshift](https://docs.atlan.com/llms/connectors/amazon-redshift/mine-amazon-redshift/llms.txt) - tables, views, and columns. Expensive queries and compute costs for Amazon Redshift assets are currently unavailable due to limitations at source.
- [Databricks](https://docs.atlan.com/llms/connectors/databricks/extract-lineage-and-usage-from-databricks/llms.txt) - tables, views, and columns. Expensive queries for Databricks assets are currently unavailable due to limitations of the [Databricks APIs](https://docs.databricks.com/api/workspace/queryhistory/list).
- [Google BigQuery](https://docs.atlan.com/llms/connectors/google-bigquery/mine-google-bigquery/llms.txt) - tables, views, and columns
- [Snowflake](https://docs.atlan.com/llms/connectors/snowflake/mine-snowflake/llms.txt) - tables, views, and columns

Usage and cost metrics for [Microsoft Power BI](https://docs.atlan.com/llms/connectors/microsoft-power-bi/mine-microsoft-power-bi/llms.txt) will be added in the future.

## Filter asset usage by users

You can track total assets queried and storage consumption by users in your organization.

To filter asset usage by a user:

1. From the left menu in Atlan, click **Reporting** and then click **Usage & Cost**.
2. From the _Usage & Cost_ dashboard, click the **Queried by** filter and select the user by whom you want to filter usage metrics.
3. (Optional) To further [refine your search](https://docs.atlan.com/llms/catalog/discovery/use-the-filters-menu/llms.txt), click **More filters**.

You will now be able to view usage and cost metrics for a specific user! 🎉

## View least used assets

You can find suggestions for deprecating assets based on the following factors:

- Tables and views without any lineage
- Asset size less than 100 GB
- Assets not queried at source in the last 30 days
- Less popular assets not updated at source in the last 3 or 6 months

To view least used assets:

1. From the left menu in Atlan, click **Reporting** and then click **Usage & Cost**.
2. From the _Usage & Cost_ dashboard, scroll down to _Review your tables & views_.
3. (Optional) To further [refine your search](https://docs.atlan.com/llms/catalog/discovery/use-the-filters-menu/llms.txt), click **More filters**.
4. Click **View assets** for any card to view a list of suggested assets for deprecation in the sidebar.
5. (Optional) In the top right of the sidebar, click the **Export** button to [export filtered assets](https://docs.atlan.com/llms/governance/integrations/export-assets/llms.txt) to a spreadsheet.

## Filter assets by context

Discover the top 25 most popular, most expensive, and most queried tables and views from the usage and cost dashboard. This can provide you with additional context regarding asset usage across the organization.

:::info **Did you know?** 
 The compute cost for an asset is split between read and write queries, allowing you to better understand the cost breakdown for individual assets.

:::

To filter assets by context:

1. From the _Usage & Cost_ dashboard, scroll down to _Top tables & views_.
2. In the _Top tables & views_ section, click the filters menu, and depending on the type of asset metrics you'd like to view:
 - Click **Most** **Popular** to view the top 25 most popular assets. 
 - Click **Most** **Expensive** to view the top 25 most expensive assets.
 - Click **Most Queried** to view the top 25 most queried assets.
