Where to look when a pipeline misbehaves. Start with Troubleshooting VAST DataEngine for symptoms without a message, and search the DataEngine error reference when a command prints an error.
- Troubleshooting VAST DataEngine: Diagnose pipelines stuck in InProgress, events that don't arrive, handler failures and changes that don't take effect, by symptom.
- DataEngine error reference: Error messages from vastde, the cluster and the runtime while you build, register and deploy, with the cause and fix of each.
