>Description:
net/mrtg ships with an envstat2mrtg perl script that intends
to process envstat(8) output to mrtg's
expectations. Unfortunately, what the script expects as input
is not quite what envstat(8) will produce, and so the former's
output is not useful, and probably hasn't been in years.
>How-To-Repeat:
# envstat -s coretemp0:cpu0\ temperature

From the code,
chop $line;
if ($line =~ m|^[\s\t]+(\w+)$|)
{
[...]
envstat2mrtg expects one line starting with whitespace, then
something alphanumeric (which it returns,) then EOL.
It is neither suited to multi-line input, nor would it
recognize current envsys(8)'s '<whitespace> <label with
optional whitespace> <colon> <whitespace> <value> <whitespace>
<unit> <EOL>' format.
>Fix:
Find a Perl hacker, then update the regexps.
Or, better, use the output of 'envstat -s', which was made to
be processed automatically. I guess perl could do that, but
unfortunately, my XML fu is marginal.
