async changes to support 40749

https://gerrit.openbmc-project.xyz/c/openbmc/sdbusplus/+/40749

Is currently proposing changing these APIs to use C++ asio style
callbacks instead of the javascript callbacks.  This was the only usage
of these callbacks that I found, so this patchset is to move to the new
type.

Requires 40749 to be merged before this will build.

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].
