What the models said about Zabbix
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Two of two in this category shown.
“Free/Open Source. Extremely powerful and customizable, but requires significant Linux/sysadmin expertise to maintain and tune. Only choose this if you have strong engineering talent.” Qwen 3.7 Flash · scale prompt · soft negative
“The best network monitoring tool for a company with a limited budget is Zabbix, as it is open-source and free to self-host” Llama 4 Maverick · budget prompt · first choice
What the models said about LibreNMS
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Four of four in this category shown.
“Five-minute defaults, notably associated with LibreNMS, can miss short congestion bursts and interface flapping” Perplexity Sonar · negative prompt · soft negative
“My suggestion: Start with LibreNMS. It strikes the best balance between a modern interface, automatic device discovery, and being entirely free forever” Qwen 3.7 Flash · budget prompt · first choice
“If you have a Linux admin on staff, start with LibreNMS (for network gear) or Zabbix (for everything).” Gemini 3.5 Flash · budget prompt · first choice
“Zabbix and LibreNMS are excellent open-source choices” Mistral Small · budget prompt · first choice
