## What it is
Netflix Servo is a Java library for exposing and publishing application metrics, primarily via JMX, with flexible publishing to reporting systems and services like Amazon CloudWatch. It is deprecated and receives minimal maintenance; new projects should use Netflix Spectator instead.

## Use cases
- expose application metrics from a Java app via JMX
- publish JVM metrics to Amazon CloudWatch
- poll and report application metrics to internal monitoring systems
- instrument legacy Java services with minimal code
- keep existing Netflix OSS apps that depend on servo working

## When to choose
- you maintain legacy software that already depends on Servo
- you need a lightweight JMX-based metrics interface in Java

## When to avoid
- starting a new Java project - use Netflix Spectator instead
- you need actively developed metrics features or modern telemetry (OpenTelemetry)
- you want non-JVM platform support

## Facets
- artifact type: library
- maturity: maintenance
- function: monitoring, logging
- domain: monitoring, developer-tools, backend
- platform: jvm, cross-platform
- tags: metrics, jmx, application-metrics, deprecated, netflix
