What GCP resources do you find hardest to track for cost waste? Sharing a scanner I've been building Been working on a read-only GCP cost scanner for a while. Figured the rule list might be worth sharing, both as a reference and to hear what I'm missing for people running real GCP workloads. **Hygiene rules (5):** * Stopped/terminated Compute Engine VMs (attached disk charges continue regardless) * Unattached Persistent Disks * Disk snapshots older than 90 days * Reserved static external IPs in RESERVED state ($0.01/hr whether used or not) * Cloud SQL instances with zero connections for 14+ days **AI/ML rules — opt-in with** `--category ai` **(5):** * Vertex AI Online Prediction endpoints with an always-deployed replica floor and zero * observed requests — these stay billed even with no traffic * Vertex AI Workbench instances with no activity (still tightening this one) * Vertex AI training jobs running well beyond a normal threshold (still tightening this one) * Cloud TPU nodes in READY state with near-zero…
