Resolves maybe-uninitialized error for std::function object, which shows
when compiling with optimizations.

Tested:
CI build passed.

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]

How to build

There are two way to build telemetry service:

  • using bitbake in yocto environment
  • using meson as native build

To build it using bitbake follow the guide from OpenBMC docs[5]. To build it using meson follow the quick guide to install meson[6] and then run below commands

meson build
cd build
ninja

After successful build you should be able to run telemetry binary or start unit tests

./tests/telemetry-ut
./telemetry

In case if system is missing boost dependency, it is possible to build it locally and set BOOST_ROOT environment variable to location of built files for meson. After this change meson should be able to detect boost dependency. See [7] for more details.

Notes

More information can be found in OpenBMC docs repository [8].
