Telemetry

This component implements middleware for sensors and metrics aggregation.

Capabilities

This application is implementation of Telemetry proposed in design[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]
