[mrtg] Re: unknown values

[Tobias Oetiker]

Hi Steve,

the reson this works is because mrtg sends the target lines through
an eval pass after substituting the target expressions with perl
variable names ... what it poils down to is, that you can use any
perl code in a target line that does not look like a taret itself
.. and you have to make sure that the target is separated from the
rest of the code by whitespace ...

ps this btw is not new, I just never bragged about it ...
