Get input from user

i recently configured netflow in my network and i created dashboard for monitoring a specific server.
now i want to use same dashboard for monitoring all servers.

for example now i monitor with this dashboard, if i want to monitor what should i do?

one solution is download json file of dashboard and import it and change ip address of server in all panels.

i want to know if there is a better solution like creating a textbox and get ip address of server from user and change ip address in all panels?
