Link not rendering color (grey) -- solved

[marcosramos]

After a few Links created I started to create links before others because of ones beeing over the others (layer like).

Anyways, some of them are shown in grey like they have no traffic. Like the picture 1 shows.
Other times only half the link is *rendered* (like picture 2)

Anyways, when I hover the mouse at it, it shows the correct graph and there's traffic.

Any ideas about it ?

memory_limit on both php.ini (cli and apache's) is set to 64mb ram. As the box got 2gb ram (quite enough)

The map picture is 1100x800 +-

Great work on this great tool!

If your SCALE lines don't cover the full 0-100% range, you can get white links. If you are getting exactly 0, then you can get grey ones.

Be aware that 0->1 and 2->3 doesn't cover 1.3, for example

Check your cacti.log though - I think you'll see some warning in this situation.

If you are getting 0 and you don't expect to, it might be that the DS names are different for those RRDs. That sounds unlikely in your situation, but again, there would be a warning in the cacti.log

Hey Howie,

Thanks for that quick help. Yes indeed I had some issues in the config that needed correction.
Anyways, why, in some cases, the link is only half rendered and some other times full rendered ?

I don't really understand what you mean here. Apart from being white, those links look normal to me

Howie,

Nevermind, the error just confused me and I've got a load of work.

I'm greatful for your help! Thank you very much and keep up the good work

Howie:

Afterall I was not work-drunk

There's a picture of what I meant.
There is traffic, there are no errors on the log but half the link is displayed in white color. Seems it is *random*...

memory_limit is now set with 128mb ram (apache was restarted after).

EDIT: The next weathermap appeared like pic 2

EDIT2: There is always traffic on those links. Noticeable links.

What do your SCALE lines look like?

[marcosramos]

Code: Select all

SCALE DEFAULT 1 24   0 240 0   240 240 0
SCALE DEFAULT 25 74   240 240 0   240 0 0
SCALE DEFAULT 75 100   240 0 0   15 15 15

EDIT: Do i need to set 1 24 to 0 24 ?

DUH .. that might do it...

[Howie]

Right. So if your value was 0.5% or 25.5% or 74.5%, then there would not be a matching line in the scale, and you would get white.

Try:

Code: Select all

SCALE DEFAULT 0 25  0 240 0   240 240 0
SCALE DEFAULT 25 75   240 240 0   240 0 0
SCALE DEFAULT 75 100   240 0 0   15 15 15 

instead.

Ok mate that should do it.

Thanks for the support!

Anyways for a 0% traffic usage could i set

SCALE 0 0 some color
SCALE 0 25 other color ?

So that real 0% is in <some color> and >0% is in <other color> ?

SCALE 0 25 other color ?

Yes. That's correct.

[marcosramos]

Code: Select all

SCALE DEFAULT 0 255 255 255 [b]< real 0%[/b]
SCALE DEFAULT 0 1 165 249 165 0 240 0 [b]< greater than 0% until 1%[/b]
SCALE DEFAULT 1 25 0 240 0 240 240 0 [b]< and so on...[/b]
SCALE DEFAULT 25 75 240 240 0 240 0 0
SCALE DEFAULT 75 100 240 0 0 15 15 15

The problem is: when a link is reall 0% (down for example) it takes the 2nd value and not the 1st...
If you want i can send another screenshot.

[Howie]

Code: Select all

SCALE DEFAULT 0 255 255 255 [b]< real 0%[/b]
[/quote]

that should be
[code]
SCALE DEFAULT 0 0 255 255 255

(TWO zeros). You should see in the cacti.log that the first line is currently being ignored, because it's invalid.

great great great!

Perfect now mate!

All perfect!

Thank you very much once again!
