# @brief Configures Netdata alerts and notifications
# @description
#     This script installs additional alerts and enables notifications if Netdata is installed. Email notifications are configured
#     using the provided email address. Slack notifications are configured if `SLACK_WEBHOOK_URL` and `SLACK_NETDATA_ALARMS_CHANNEL`
#     are provided. Syslog integration is configured if `SYSLOG_NETDATA_ENABLE` and `SYSLOG_NETDATA_RECIPIENTS` are provided.
#     If the OS is Debian based, Netdata shows the number of CVEs in currently installed packages.
