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.

cat << NONROOT
${TPUT_RED}${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() {
netdata_banner
progress "installer command line options"
cat << HEREDOC
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-ebpf Disable eBPF Kernel plugin. Default: enabled.
--disable-cloud Disable all Netdata Cloud functionality.
--require-cloud Fail the install if it can't build Netdata Cloud support.
--force-legacy-cxx Force usage of an older C++ standard to allow building on older systems. This will usually be autodetected.
--enable-plugin-freeipmi Enable the FreeIPMI plugin. Default: enable it when libipmimonitoring is available.
--disable-plugin-freeipmi Explicitly disable the FreeIPMI plugin.
--disable-https Explicitly disable TLS support.
--disable-dbengine Explicitly disable DB engine support.
--enable-plugin-go Enable the Go plugin. Default: Enabled when possible.
--disable-plugin-go Disable the Go plugin.
--disable-go Equivalent to --disable-go-plugin
--enable-plugin-nfacct Enable nfacct plugin. Default: enable it when libmnl and libnetfilter_acct are available.
--disable-plugin-nfacct Explicitly disable the nfacct plugin.
--enable-plugin-xenstat Enable the xenstat plugin. Default: enable it when libxenstat and libyajl are available.
--disable-plugin-xenstat Explicitly disable the xenstat plugin.
--enable-plugin-systemd-journal Enable the systemd journal plugin. Default: enable it when libsystemd is available.
--disable-plugin-systemd-journal Explicitly disable the systemd journal plugin.
--enable-exporting-kinesis Enable AWS Kinesis exporting connector. Default: enable it when libaws_cpp_sdk_kinesis
and its dependencies are available.
--disable-exporting-kinesis Explicitly disable AWS Kinesis exporting connector.
--enable-exporting-prometheus-remote-write Enable Prometheus remote write exporting connector. Default: enable it
when libprotobuf and libsnappy are available.
--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.
--disable-logsmanagement Disable the logs management plugin. Default: autodetect.
--enable-logsmanagement-tests Enable the logs management tests. Default: disabled.
