[saurabh-gore]

Describe what happened:
We are trying to enable power support for datadog-agent.We were able to build version 7.33.1 on ppc64le( RHEL 8.4).
However while testing we observed 4 test failures. ( please refer attached test logs datdog-agent logs.txt )

bash  : # invoke test   --skip-linters --build-exclude=systemd

Output =>
