Hide link when no data ?

[syl22]

Hello Everybody !

simple question:
Is it possible to hide a link when there is no data to display ?

I have a map whose link data are coming from a text file (Target /xxx/output.txt).
I would like to hide link when there is no valid data to display .



Thanks in advance !

I guess the closer you can get to that is

Code: Select all

OUTLINECOLOR 255 255 255
BWOUTLINECOLOR 255 255 255

If your background color is white and the scale defines 255 255 255 for 0 1, to say something. But it'd be a pain to edit those links hehe

No other way that I'm aware of.

I'm just curious, may I ask in what case would this be useful for you?

I just saw this... have you tried with DEBUG logging? (or even checked the cacti.log?) You should get more information about what is going on. Look for lines with ReadData in them.
