First of all, you really should specify the mode you want Perl to open your file with. So:
Secondly, the reason you're getting multiple buttons is because as you go over each line in your log file, you're printing out either a red button, a yellow button or whatever the previous value of $button was. Do you want coloured buttons for every line in your file? Or do you want one just for the last line? Alternately, do you want to have one button representing the biggest problem? As in, if there was something that signalled a "red" button and a "yellow" button that you only get one red one? I'm going to assume that you want the latter. So that if all the lines in the file look boring, you get 1 green button. If any of them are worth warnings, you get a yellow, and if any are red, you get a red; but in all cases you only get one button. I'm also going to assume that you only need to print the header out once, and that you will always print it.
A flaw with this approach is that as time moves on, red buttons may not longer mean anything. For example, if the log file contains data from 2 days ago, then a "DOWN" back then has probably been resolved now. As such, you may find it useful to have a look at Log::Tail to allow you to tail log events on live logs, and to record when the red and yellow events happen so that you can reduce their severity over time. Such a program will be much more complicated than this though. I hope this helps.
