# Real User Monitoring

Use the Coralogix MCP server to query and analyze Real User Monitoring (RUM) data directly from your IDE. Find top errors, track user interactions, monitor Web Vitals, and troubleshoot frontend and mobile application performance without leaving your coding environment.

Setup requirements are identical to the existing MCP server configuration.

## Example prompts

### Error and crash analysis

```text
What are the top errors in my web app this week?
```

```text
Show me the most impactful frontend errors by affected users.
```

```text
Are there any network request failures in the dashboard app?
```

```text
What crashes are happening in our mobile app?
```

### Performance monitoring

```text
Which pages have the slowest load times?
```

```text
Show me Web Vitals (LCP, CLS, FID) trends for our portal.
```

```text
Are there any long tasks blocking the main thread?
```

### User behavior analysis

```text
What are users clicking on the checkout page?
```

```text
Show me the most common user interactions on the settings page.
```

### Mobile monitoring

```text
Show me CPU and memory usage from our Android app.
```

```text
What's the crash rate on iOS this week?
```

```text
Are there any ANR issues on Android?
```

## Tools

| Tool                         | Description                                                                                                                                      |
| ---------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| `read_rum_log_intro_docs_v1` | Loads the RUM data reference documentation to help AI agents understand RUM log structure and query patterns. Run this before querying RUM data. |
| `read_rum_sdk_docs_v1`       | Loads the Coralogix RUM SDK setup guide and API reference. Useful for troubleshooting SDK integration issues from your IDE.                      |

## Common use cases

- Find top RUM errors for your application, filter by team or URL, and fix them in your code—without leaving your editor.
- Understand what users are clicking, what they abandon, and identify drop-off patterns that surface underlying errors.
- Track Core Web Vitals and load time trends across pages to catch regressions before they affect users.
