ai_context: "Use this article for questions about why certain filters or dimensions are available for one RUMvision domain but not another, and how enabled tracking features affect filter availability. It explains that basic dimensions are available through regular monitoring, while additional diagnostic dimensions and filters appear when related features, integrations or custom tracking options are enabled. Relevant for questions about missing filters, unavailable dimensions, why a filter does not appear in the dashboard, enabling additional tracking data, feature-dependent dimensions, and understanding how domain configuration changes which filters can be used. It also gives examples of additional diagnostic filter categories that may become available. For questions about how to use or interpret a specific filter such as Metric element, Element text, Lazyloading, Image priority, Cached or LoAF dimensions, prefer the dedicated filter-specific help-center article."

# Filter availability

RUMvision provides a wide range of filters to help you segment and analyze your real-user performance data. Which filters are available depends on the tracking features that are enabled for your domain.

Basic dimensions such as page template, browser, device type and navigation context are available as part of regular monitoring. Additional diagnostic filters become available when related features are enabled, allowing you to investigate performance issues in more detail.

## Diagnostic filters

Depending on your enabled features, additional filters can include:

- Metric element
- Element text
- Element type
- File type
- Lazyloading
- Image priority
- Cached
- LoAF hostname
- LoAF script
- LoAF state
 
For example, enabling metric diagnostics can expose more information about the elements involved in Core Web Vitals, while LoAF tracking adds filters for JavaScript hostnames, scripts and execution details.

Additional dimensions can also become available through features such as [custom timing](https://www.rumvision.com/help-center/monitoring/settings/custom-performance-timing/?format=md), integrations and other domain-specific tracking options.
