Advanced Features

logme includes a set of features designed for real-world production usage.

---

Message frequency control

logme allows limiting how often messages appear.

Examples:

• log once
• log every N times

This is useful in hot paths to reduce log noise.

---

Boot / early logging

log messages can be captured before full configuration is loaded.

This helps diagnose startup issues that would otherwise be lost.

---

Precheck mechanism

Before formatting and argument evaluation, logme performs a lightweight check.

If logging is disabled:

• formatting is skipped
• arguments are not evaluated

This minimizes overhead in performance-critical code.

---

Runtime control

Logging behavior can be changed without restarting the application.

This includes:

• enabling/disabling channels
• changing levels
• adding backends

---

Obfuscation support

logme supports obfuscation of sensitive data in logs.

This allows using logs in environments where security matters.

---

Summary

These features are designed to make logging usable in production systems, not just during development.
