NativeEdge: Device Shows "No Data Available" in Metrics Tab
Сводка: A NativeEdge device shows “No Data Available” in the Dell Automation Platform (DAP) Metrics tab because the telegraf handler depends on a machineID message from the Orchestrator (EO), which may be missing or delayed. ...
Симптомы
A NativeEdge device does not report metrics within the Dell Automation Platform (DAP) Metrics tab.
The message displayed is “No Data Available”.
The node appears online in the DAP interface.
Причина
The Telegraf handler receives a machineID from Edge Orchestrator (EO) from a NATS message (endpoint:telegraf:SetEnv), writes it to the ecetelegraf.env file, and restarts the Telegraf service. This creates a dependency on EO sending a message before Telegraf can report metrics with the correct machine identity.
When this message delivery fails or is delayed, Telegraf cannot report metrics properly. The dependency exists in NativeEdge 4.2.0.0 and earlier versions.
Разрешение
Perform the following steps to restore metrics reporting:
- Run a full factory reset of the affected device.
- Before re‑onboarding the device, remove the voucher from the orchestrator. The user does not need to remove the voucher from the portal.
- Re‑add the voucher to the orchestrator.
- Re‑deploy the system and re‑onboard the device.
- Verify that metrics appear successfully in the Dell Automation Platform Metrics tab.
Permanent fix:
Upgrade to NativeEdge 4.3 or later. This version implements autonomous Telegraf configuration during agent startup, eliminating the dependency on Edge Orchestrator message delivery.
