# Sigma Usage Data

Euno tracks warehouse workloads generated by Sigma resources to help teams understand cost drivers, identify frequently accessed content, and maintain a healthy BI environment.

{% hint style="info" %}
If you want user-level impression data from Sigma exports stored in S3 or GCS, see [Sigma Impressions Data](/using-euno/usage-optimization/sigma-impressions-data.md) and the [Sigma Impressions integration setup guide](/sources/business-intelligence/sigma-impressions-integration.md).
{% endhint %}

### **Warehouse Query Records (from your data warehouse)**

**Definition:**\
Read queries issued to the data warehouse as a result of users interacting with Sigma workbooks, and elements. When Sigma submits a query to the warehouse, it includes metadata that allows Euno to attribute the workload back to a specific Sigma resource.

**Source:**\
Warehouse query logs (e.g., Snowflake), provided that Sigma usage observation is enabled in your data-warehouse source configuration in Euno.

{% hint style="info" %}
This feature is currently supported only for Snowflake, with additional platforms planned for future releases.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.euno.ai/using-euno/usage-optimization/sigma-usage-data.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
