Wrong scale value being used

[Dunc <dunc.lockwood@xxxxxxxxxxxxx>]

Hi all,

I've got a weird one which I hope someone can help me debug. I've
attached a file with the relevant debug output.

I'm monitoring some temperatures, and most are working just fine, but on
one link the value read, and the value used to generate the colour are
out by a factor of 10^6

The relevant bits are here........

DEBUG: [ReadData@xxxxxxxxxxxxxxxxxxxx:964]
/usr/local/etc/mrtg-tbsh/weathermap/ASHENVIRODEV/php_weathermap.conf:
ReadData complete for LINK Chiller-3Condenser-3Return: 22.5 22.5
DEBUG: [NewColourFromPercent@xxxxxxxxxxxxxxxxxxxx:1256]
/usr/local/etc/mrtg-tbsh/weathermap/ASHENVIRODEV/php_weathermap.conf:
NCFPC Chiller-3Condenser-3Return CONDENSERRETSCALE 2.25E-5 '' 0_1 0 0 0
DEBUG: [NewColourFromPercent@xxxxxxxxxxxxxxxxxxxx:1256]
/usr/local/etc/mrtg-tbsh/weathermap/ASHENVIRODEV/php_weathermap.conf:
NCFPC Chiller-3Condenser-3Return CONDENSERRETSCALE 2.25E-5 '' 0_1 0 0 0


Now in my scale, I have black (0 0 0) for values between 0 and 1, and so
the generated colour is correct for what it thinks the value is, but
I've got no idea why the value changes from 22.5 to 2.25E-5 within the
space of a line above.

Anyone any ideas?


By the way, this happened with 0.97 but I've got the same behaviour with
0.97a too as I've just tried it.

Cheers,

Dunc
