+
+  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
+
+      $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.

+
+USAGE: ${PROGRAM} [options]
+       where options include:
+
+  --install <path>           Install netdata in <path>. Ex. --install /opt will put netdata in /opt/netdata, this option is deprecated and will be removed in a future version, please use --install-prefix instead.
+  --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-go               Disable installation of go.d.plugin.
+  --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.
+  --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-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-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.
+
+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]
+
+If you also need to provide different LDFLAGS, use something like this:
+
+  LDFLAGS="<extra ldflag options>" ${PROGRAM} [options]
+
+or use the following if both LDFLAGS and CFLAGS need to be overridden:
+
+  CFLAGS="<gcc options>" LDFLAGS="<extra ld 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

+

+
+apps.plugin is performing a hard-coded function of data collection for all

+any task, so it is pretty safe to do this.
