## What it is
Munin is a networked resource monitoring tool that surveys servers and nodes, stores metrics in RRD files, and presents them as graphs through a web interface. It is plug-and-play by design, shipping with hundreds of monitoring plugins and supporting custom plugins written in any language.

## Use cases
- monitor server cpu memory and disk usage over time
- graph resource trends across a fleet of servers
- get alerts when a server metric goes wrong
- diagnose what changed before a performance problem
- plan capacity for servers and applications
- monitor services via snmp without agents
- set up server monitoring in under 10 minutes

## When to choose
- you want plug-and-play server monitoring with minimal configuration
- you need historical graphs and trend analysis of system resources
- you want a self-hosted, lightweight alternative to heavier monitoring stacks
- you need to monitor anything via custom plugins in any language

## When to avoid
- you need second-level real-time metrics or high-frequency polling
- you want a modern UI or cloud-native metrics stack
- you need large-scale dynamic environments like container orchestration
- you prefer agent-based push models like Prometheus ecosystems

## Facets
- artifact type: application
