## What the models said about Datadog

- "costs escalate rapidly, with log management and APM billed separately ... making it hard to predict monthly costs" (Claude Haiku 4.5, negative prompt, hard negative)
- "It is the go-to for SaaS B2B teams already on AWS/Azure/GCP who want rapid onboarding and SaaS management, but it is metered and can get expensive at scale." (Muse Glimmer 30B, direct prompt, first choice)

## What the models said about Zabbix

- "Avoid Nagios and raw Zabbix if you value speed and ease-of-use over granular control." (Qwen 3.7 Flash, negative prompt, hard negative)
- "Avoid Zabbix if you need modern UI and simplicity, as its user interface feels dated." (Claude Haiku 4.5, negative prompt, hard negative)
- "Zabbix – best all-in-one for traditional infrastructure ... Need one install with UI, alerting and auto-discovery and minimal ops overhead → Zabbix." (Muse Glimmer 30B, budget prompt, first choice)
