## Warned against

- Datadog: 19 of 64 labels negative. "Platforms like Datadog ... charge heavily per host, per container, and especially per "custom metric" (high cardinality), leading to highly volatile, unpredictable bills." (Gemini 3.5 Flash, budget prompt)
- New Relic: 15 of 53 labels negative. "Platforms like New Relic charge up to $349/month per Full Platform user... over $4.1 million per year just in seat licenses" (Gemini 3.5 Flash, budget prompt)
- Dynatrace: 9 of 51 labels negative. "When to Avoid: Cost-sensitive orgs or those avoiding deep vendor lock-in (proprietary OneAgent)." (Grok 4.1 Fast, negative prompt)
- Splunk: 7 of 19 labels negative. "When to Avoid: High-volume log-heavy workloads in global setups. Post-Cisco acquisition, integration lock-in has frustrated some users." (Grok 4.1 Fast, negative prompt)
