## Warned against

- Datadog APM: 17 of 60 labels negative. "Notorious for "bill shock": Invoices commonly run 3-12× higher than initial estimates ... Datadog's billing practices and AppDynamics' post-acquisition decline represent the highest current risks" (Kimi K2, negative prompt)
- Dynatrace: 13 of 62 labels negative. "it is also noted for being the most expensive commercial APM at scale and having a monolithic agent model that may conflict with teams that want fine-grained control" (Llama 4 Maverick, negative prompt)
- AppDynamics: 10 of 42 labels negative. "Avoid these if your enterprise is actively migrating to Kubernetes, multi-cloud environments, or serverless workloads." (Gemini 3.5 Flash, negative prompt)
- New Relic: 7 of 59 labels negative. "your seat bill alone will quickly spiral into millions of dollars... However, be aware that forecasting CCUs is more complex" (Gemini 3.5 Flash, budget prompt)
