Zabbix vs Prometheus

Zero of fourteen models named Zabbix first on the direct prompt; zero named Prometheus. Both were named by all fourteen models and Zabbix carries 46 labels and Prometheus 31, so the shares are not directly comparable.

Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the infrastructure monitoring page.

By framing

How many of the fourteen models made each the first choice, per way of asking, and how many argued against it.

Bold names in an answer are the products the judge labeled a first choice; a model naming several gives each of them that label. The full answer text for every row is in the record.

“Avoid "turnkey" open source stacks when you lack the team to maintain upgrades... an unpatched Prometheus/Grafana deployment is a liability.” Muse Glimmer 30B · negative prompt · soft negative
“Open-source tools like vanilla Prometheus, while powerful, can require significant operational expertise to scale properly.” MiniMax M2.5 · negative prompt · soft negative
“its local storage isn’t clustered or replicated. Don’t treat one instance as a highly available, durable monitoring backend” GPT-6 Luna · negative prompt · soft negative
