“Paessler PRTG is not well-suited for cloud-native or container-heavy environments.” Claude Haiku 4.5 · negative prompt · hard negative
“Limited to 100 sensors in the free tier ... paid tier can get expensive ... the UI feels dated” DeepSeek V4 Flash · negative prompt · soft negative

“PRTG - If you want a more established tool with a free version and willing to scale up later” MiniMax M2.5 · budget prompt · first choice
“the best *default* choice is usually PRTG Network Monitor” Perplexity Sonar · direct prompt · first choice

What the models said about Prometheus
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Three of three in this category shown.
“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
