You are attempting to install netdata as a non-root user, but you plan
to install it in system paths.
Please set an installation prefix, like this:
$PROGRAM ${@} --install-prefix /tmp
or, run the installer as root:
sudo $PROGRAM ${@}
We suggest to install it as root, or certain data collectors will
not be able to work. Netdata drops root privileges when running.
So, if you plan to keep it, install it as root to get the full
functionality.

${TPUT_RED}${TPUT_BOLD}IMPORTANT${TPUT_RESET}:
You are about to install netdata as a non-root user.
Netdata will work, but a few data collection modules that
require root access will fail.
If you are installing netdata permanently on your system, run
the installer like this:
${TPUT_YELLOW}${TPUT_BOLD}sudo $PROGRAM ${@}${TPUT_RESET}
NONROOT

USAGE: ${PROGRAM} [options]
where options include:
--install-prefix <path> Install netdata in <path>. Ex. --install-prefix /opt will put netdata in /opt/netdata.
--dont-start-it Do not (re)start netdata after installation.
--dont-wait Run installation in non-interactive mode.
--stable-channel Use packages from GitHub release pages instead of nightly updates.
This results in less frequent updates.
--nightly-channel Use most recent nightly updates instead of GitHub releases.
This results in more frequent updates.

--disable-exporting-prometheus-remote-write Explicitly disable Prometheus remote write exporting connector.
--enable-exporting-mongodb Enable MongoDB exporting connector. Default: enable it when libmongoc is available.
--disable-exporting-mongodb Explicitly disable MongoDB exporting connector.
--enable-exporting-pubsub Enable Google Cloud PubSub exporting connector. Default: enable it when
libgoogle_cloud_cpp_pubsub_protos and its dependencies are available.
--disable-exporting-pubsub Explicitly disable Google Cloud PubSub exporting connector.
--enable-lto Enable link-time optimization. Default: disabled.
--disable-lto Explicitly disable link-time optimization.
--enable-ml Enable anomaly detection with machine learning. Default: autodetect.
--disable-ml Explicitly disable anomaly detection with machine learning.
--disable-x86-sse Disable SSE instructions & optimizations. Default: enabled.
--use-system-protobuf Use a system copy of libprotobuf instead of bundled copy. Default: bundled.
--zlib-is-really-here
--libs-are-really-here If you see errors about missing zlib or libuuid but you know it is available, you might
have a broken pkg-config. Use this option to proceed without checking pkg-config.
--disable-telemetry Opt-out from our anonymous telemetry program. (DISABLE_TELEMETRY=1)
--skip-available-ram-check Skip checking the amount of RAM the system has and pretend it has enough to build safely.
--dev Do not remove the build directory - speeds up rebuilds
