define hostgroup{

alias basic clients
members mymachine1, machine2
}
define hostgroup{
hostgroup_name your-routers
alias routers
members router1
}
define hostgroup{
hostgroup_name linux-servers ; the name of the hostgroup
alias linux Servers ; Long name of the group
members localhost, linuxmachine1, linuxmachi
}
define hostgroup{
hostgroup_name windows-servers
alias Windows Servers

}
