# This script installs telegraf and ioping and our script telegraf-ioping.sh
# to the /usr/bin directory.
#
# The reasons we don't install to /usr/local/bin are:
# 1. On SLES and RHEL, the PATH of sudo (secure_path setting in /etc/sudoers)
#    does not include /usr/local/bin.
# 2. On macOS /usr/local/bin does not even exist early in provisioning.
