Threshold is a simple application based on systemd that automatically brings down a network interface after a specified amount of data has passed through it. Internally, it reads from the /proc/net/dev file to monitor network usage and uses the netlink package to manage network interfaces.
Since this application requires root privileges, you’ll need to install Threshold as the root user and configure the environment accordingly. Assuming you are already logged in as root, add the following lines to the /root/.bash_profile file:
export PATH="$PATH:$HOME/go/bin"
export GOPATH="$HOME/go"After updating the file, apply the changes by running:
source /root/.bash_profile
You can now install Threshold using the go install command:
go install github.com/enindu/threshold@latest
You can run Threshold using the following syntax:
threshold <command>:<subcommand> [arguments]
threshold [flags]
To display the version message:
threshold -v # or "threshold --version"
To display the help message:
threshold -h # or "threshold --help"
