NewColourFromPercent Error

Post by Syngress »

Hi,

After upgrading my weathermap from 0.941 to 0.96a I am seeing the below error in my logs on occasion...

07/07/2009 09:25:10 AM - WEATHERMAP: Poller[0] WARNING: [Map 24] Foundry Network: NewColourFromPercent: Scale DEFAULT doesn't include 0.0099416954208% while drawing item ps-1.CHC2-ps-3.CHC2 [WMWARN29]

Any ideas?

The scale called DEFAULT doesn't have a line that covers percntages from 0 to 1. What should this message have said, that would explain this better? That's a serious question... several people have asked
about this one, and I thought it was obvious, but I guess not.
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).

Hi Howie,

In our 0.941 config files we didn't have a 0 1 - we had a 0.01 10 0 255 0

This meant that any link that had a small amount of traffic was green, and any link with no traffic was automatically white.

I would guess something has been update between 0.941 & 0.96a so I have now amended our configs and everything is ok :)

The log message does make sense, its just it seemed by default in 0.941 the link would have been white (or no fill).

Thanks

Yep - I did add that warning in 0.96. I also added a SET variable to disable it :-) I have just tweaked the message slightly for 0.97, too.

It's not *that* fastidious. You have a scale which doesn't cover the data that you have. So make it cover it!

Usually, it's:

Code: Select all

SCALE DEFAULT 0 1 255 255 255
So that there's a colour defined for 0-1%. Prior to 0.96, the DEFAULT scale that weathermap would insert for you had this problem, which is probably why you have it.

OR, you can disable the warning instead with:

Code: Select all

SET nowarn_scalemisses 1
in the top section of the map config file.

Must the scale entry be 0-1 to cover a percent of 0.x? I have an entry of 0-20 for the bottom of the scale, yet still see the warning for data between 0 and 1.

No... yours should work too. Could you paste your scale lines and the warning please?

Oops I think this was user error. :) I had copied an example scale that started with 1-10 and eventually changed it to 0, but during that period the log was showing a clip of 0.xxx to 1. I now have a scale entry of 0-10 and it seems to be working just fine, including clipping negative percentages from an aggregate to 0. Thanks!
