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
