Telemetry

This component implements middleware for sensors and metrics aggregation.

Capabilities

This application is implementation of Telemetry proposed in OpenBMC design docs [1].

It's responsible for:

• on-demand creation of metric reports,
  • aggregated sets of sensor values available in system [2],
• access to metric report in both pull and push model (triggers),
• run-time monitoring of sensor[3] updates.

Use-cases

• generic and centralized way to observe telemetry data inside system
• back-end for Redfish TelemetryService[4]
