# Monitoring Platform

> Dive into our guide to optimizing ML models and LLM applications with Fiddler’s monitoring tools. Learn key metrics to track data drift, performance, and more.

Fiddler Monitoring helps you detect performance issues in your production ML models and LLM applications. It provides five built-in metric types, plus support for custom metrics that you can monitor and track.

* [**Data Drift**](/observability/platform/data-drift-platform)
* [**Performance**](/observability/platform/performance-tracking-platform)
* [**Data Integrity**](/observability/platform/data-integrity-platform)
* [**Traffic**](/observability/platform/traffic-platform)
* [**Statistic**](/observability/platform/statistics)
* [**Custom Metrics**](/observability/platform/custom-metrics)

These metrics can be visualized through Fiddler's Charts and Dashboards, alerted on using Alerts, and extended with Custom Metrics, allowing for quick root cause analysis alerts.
