## What the models said about LibreNMS

- "open-source is usually a poor fit for mid-market teams" (Gemini 3.5 Flash, direct prompt, hard negative)

- "Start with LibreNMS if you want quick wins, or Zabbix if you want a long-term, scalable solution" (Kimi K2, budget prompt, first choice)
- "Zabbix (robust, but requires setup) or LibreNMS (very easy to start)" (Qwen 3.7 Flash, negative prompt, first choice)

## What the models said about Nagios

- "Nagios: Steer clear if you're not a highly technical user." (Grok 4.1 Fast, negative prompt, hard negative)
- "often an open-source option like Zabbix or Nagios Core, as they provide robust features at zero licensing cost" (Grok 4.1 Fast, budget prompt, first choice)
- "For most small businesses, Zabbix and Nagios Core are the top free choices" (Mistral Small, budget prompt, first choice)
- "Nagios Xi - a broad network and infrastructure monitoring tool with sensor-level control, suitable for mid-market IT teams." (Llama 4 Maverick, direct prompt, alternative)
