# Monitoring

Configure statistics collection and heartbeat emission for monitoring your Talon microservices.

## Overview

Talon automatically collects extensive statistics about message processing, transactions, and system resources. Configuration controls what statistics are collected, how frequently they're emitted, and the performance trade-offs.

Statistics must be balanced against performance impact. Many are enabled by default with minimal overhead, while detailed latency and per-transaction statistics can impact performance and require explicit enablement.
