ZAPP Listener

Mon, 01 Jan 0001 00:00:00 +0000

A ZAPP Listener runs a telemetry pipeline from a YAML configuration file. A listener can receive ZAPP payloads, poll Redfish endpoints, process payload batches, forward telemetry to the ZAPP Aggregator, or expose telemetry directly to consumers.

A listener pipeline can poll BMC Redfish endpoints and expose the resulting time-series telemetry directly through a grpcServer component.

ZAPP Aggregator

Mon, 01 Jan 0001 00:00:00 +0000

The ZAPP Aggregator receives telemetry from ZAPP Listeners and exposes a stable API surface for consumers. Use it when you need centralized listener fan-in, manifest visibility, and one client endpoint for telemetry subscribers.
