Well, this will only work if you really do mean "at the end of the
string", and not just the last occurrence:

     string.gsub("blabla/in0_input", "_input$", "_alarm")

The '$' character indicates that this search pattern only matches at
the end of the string.

If you DO mean the last occurrence (that may not be at the actual end
of the string), that will be trickier...
