- "Datadog Network Performance Monitoring - a versatile end-to-end monitoring solution suitable for mid-market MSPs." (Llama 4 Maverick, direct prompt, first choice)
- "If you're cloud-heavy or growing fast, LogicMonitor or Datadog offer better scalability but at higher operational cost" (Kimi K2, scale prompt, alternative)

## 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)
