# @brief Connects Netdata with Netdata's free cloud dashboard and applies some system optimizations, if necessary
|
|
# @description
|
|
# This script connects Netdata with Netdata Cloud if Netdata is installed, the `NETDATA_TOKEN` is provided, and the
|
|
# `NETDATA_ROOM` is defined. This allows you to graphically browse through system metrics on all your connected devices
|
|
# from a single free web application.
|
|
#
|
|
# This script installs additional alerts and enables notifications if Netdata is installed. Email notifications are configured
|
|
# using the provided primary email address. If the OS is Debian based, Netdata shows the number of CVEs in currently installed packages.
