${TPUT_RED}${TPUT_BOLD}Sorry! This will fail!${TPUT_RESET}
You are attempting to install netdata as non-root, but you plan
to install it in system paths.
Please set an installation prefix, like this:
$PROGRAM ${@} --install /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.
NONROOTNOPREFIX
}
banner_root_notify() {
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 installing netdata permanently on your system, run
the installer like this:
${TPUT_YELLOW}${TPUT_BOLD}sudo $PROGRAM ${@}${TPUT_RESET}
NONROOT
}
usage() {
netdata_banner "installer command line options"
cat <<HEREDOC
USAGE: ${PROGRAM} [options]
where options include:
--install <path> Install netdata in <path>. Ex. --install /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
--auto-update or -u Install netdata-updater in cron to update netdata automatically once per day
--stable-channel Use packages from GitHub release pages instead of GCS (nightly updates).
This results in less frequent updates.
--disable-go Disable installation of go.d.plugin.
--enable-plugin-freeipmi Enable the FreeIPMI plugin. Default: enable it when libipmimonitoring is available.
--disable-plugin-freeipmi
--enable-plugin-nfacct Enable nfacct plugin. Default: enable it when libmnl and libnetfilter_acct are available.
--disable-plugin-nfacct
--enable-plugin-xenstat Enable the xenstat plugin. Default: enable it when libxenstat and libyajl are available
--disable-plugin-xenstat Disable the xenstat plugin.
--enable-backend-kinesis Enable AWS Kinesis backend. Default: enable it when libaws_cpp_sdk_kinesis and libraries
it depends on are available.
--disable-backend-kinesis
--enable-backend-prometheus-remote-write Enable Prometheus remote write backend. Default: enable it when libprotobuf and
libsnappy are available.
--disable-backend-prometheus-remote-write
--enable-backend-mongodb Enable MongoDB backend. Default: enable it when libmongoc is available.
--disable-backend-mongodb
--enable-lto Enable Link-Time-Optimization. Default: enabled
--disable-lto
--disable-x86-sse Disable SSE instructions. By default SSE optimizations are enabled.
--zlib-is-really-here or
--libs-are-really-here If you get 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 Use this flag to opt-out from our anonymous telemetry progam.
Netdata will by default be compiled with gcc optimization -O2
If you need to pass different CFLAGS, use something like this:
CFLAGS="<gcc options>" ${PROGRAM} [options]
For the installer to complete successfully, you will need these packages installed:
gcc make autoconf automake pkg-config zlib1g-dev (or zlib-devel) uuid-dev (or libuuid-devel)
For the plugins, you will at least need:
curl, bash v4+, python v2 or v3, node.js

You may need to check these:
1. The package uuid-dev (or libuuid-devel) has to be installed.
If your system cannot find libuuid, although it is installed
run me with the option: --libs-are-really-here
2. The package zlib1g-dev (or zlib-devel) has to be installed.
If your system cannot find zlib, although it is installed
run me with the option: --libs-are-really-here
3. You need basic build tools installed, like:
gcc make autoconf automake pkg-config
Autoconf version 2.60 or higher is required.
If you still cannot get it to build, ask for help at github:
https://github.com/netdata/netdata/issues

You have kernel memory de-duper (called Kernel Same-page Merging,

To enable it run:

${TPUT_YELLOW}${TPUT_BOLD}echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs${TPUT_RESET}

It seems you do not have kernel memory de-duper (called Kernel Same-page

To enable it, you need a kernel built with CONFIG_KSM=y
