## What the models said for it

- "start with Zabbix or Nagios if you need comprehensive monitoring" (Mistral Small, Infra monitoring)
- "Stick to well-established, actively maintained tools like SolarWinds NPM, PRTG, Nagios, or Zeek" (MiniMax M2.5, Network monitoring)
- "Very small / legacy environment with simple host/service checks: Nagios Core." (Muse Glimmer 30B, Infra monitoring)

## And against it

- "Self-hosting tools like old Nagios configurations or unpatched legacy open-source scripts can introduce severe security vulnerabilities" (Gemini 3.5 Flash, Uptime monitoring)
- "Avoid or migrate away from these if running cloud-native, containerized, or rapidly scaling infrastructure." (Gemini 3.5 Flash, Infra monitoring)
- "Nagios is outdated and shows its age, and you should avoid it if you have cloud-native infrastructure" (Claude Haiku 4.5, Infra monitoring)
