# Monitoring

This section covers receiving and viewing telemetry (statistics) from running Talon applications.

## Overview

Talon automatically collects and reports statistics at multiple levels:

* **XVM (Server) Statistics**: Load average, memory usage, per-thread CPU utilization
* **Engine Stats**: Message throughput, object pool usage, transaction statistics
* **Per-Transaction Statistics**: Detailed performance metrics at the transaction level

By default, statistics reporting is conservative to minimize overhead. You can configure the level of detail based on your monitoring needs.

## Monitoring Components

* [**XVM Heartbeats**](/talon/operating-applications/monitoring/xvm-heartbeats.md) - Server-level statistics and health monitoring
* [**Memory Stats**](/talon/operating-applications/monitoring/memory-statistics.md) - Detailed memory statistics (heap, off-heap, IO buffers, entity lifecycle)
* [**Engine Stats**](/talon/operating-applications/monitoring/engine-statistics.md) - Message processing and engine metrics reference
* [**Per Transaction Stats**](/talon/operating-applications/monitoring/per-transaction-statistics.md) - Transaction-level performance metrics
