note that you already can link multiple triggers to a link, which will affect it's colour and draw style.
thus this request could be about adding labels to links where items could be used.

edit : it should actually be about changing link style & colour based on an item value

We are about to develop this functionnality.

What is the best way to coordinate with dev team and to submit our patch ?

Today, we have a new type of ligne for links : "link"
We draw an arrow from both host to the label box.

Now we are looking for the way to change the color of the ligne.

Anibody interested in ?

a screenshot of the double arrow line type. See attachment fleche.png

Next step: how to connect the arrow with items ....

A screenshot explaining how to setup a formula for double arrows lines.

See attachment: Popup_zabbix1.png
Today: we will test integration with zabbix 1.9

Is there a zabbix developpers who can help us for integrating our patch ?

I like it in general, not sure how it could be implemented though.

We implemented it in our system.

How can i submit a patch ?

By attaching it here.

ok, il will adapt my code to the last zabbix version and publish a patch here.

Looks a bit like my request in ZBXNEXT-1750.
Maybe we can combine the two?

@raymond: you are right, this is the same request.

In that case I'll close mine, since this issue predates it
For completeness, here is my original line of thought:

—
I would like to build a 'wheathermap' like map in Zabbix.
For this to work, I need to indicate network load on links using colours.

Currently, It is possible to change the format (line type, colour) of a link using trigger statuses however, this will greatly increase the number of triggers in Zabbix for the sole pupose of making pretty maps.
Therefor, I think it would be a good idea to be able to use a mapping based on item values, for instance:

0% - Black
1-10% - Purple
10-20% - Cyan
30-40 % - Blue
50-60 % - Yellow
70-80 % - Orange
80-100 % - Red

I would like to be able to define these mapping globally, just like value mappings so we can reuse them easily in other maps or on other links in the same map.

ZBXNEXT-4906 asks for such a functionality on elements.

Hello Zabbix Team !

any update please ?
