If you already have the infrastructure in place to monitor the latency (ie. calling GetNetStats every 30 seconds), you can use Lua's built in File I/O facilities to open the desired log file:

local latencylog = io.open("c:/wowlatency.txt","w")

-- enter whatever loop you may have
  latencylog:write(message_string_about_latency)
  -- don't forget to write a \n if it's not in the string
  -- repeat

-- after finishing the log
latencylog:close()
