Hello cacti community,

I have a question concerning cacti & PHP Network Weathermap, When I use icons on a map, i have a red background behind the icons. I would like that the label color and the background color behind icons to change with the Nagios State (via Ndo Database).

PS : Howie, if you are interested, I can give you the datasource file that I've made in order to get nagios Status for the monitored objects.

Greetings.

Mao.

Well, I'm not sure why you would get the red background in the first place. That sounds like a bug, or that you have icons with some funny transparency. Are they PNG or GIF? Do they actually have an alpha channel? I found that either mono+alpha or grey+alpha didn't work very well (can't recall which).

The normal way to do this is to have three copies of each icon (red, green, yellow, or whatever you need) and then use {node:this:blah} type stuff in the icon name. Have a look for cactihost: in the forums here to see an example for that. It works best if you can get your Nagios datasource plugin to add the extra 'notes' like the cactihost one does, to be used in the filename.

I'd be interested to see that

Ok Howie, thanks 4 your answer.
So i'm agree that it looks like a bug. The problem is ,as you can see on the screenshot below, I've the same comportment with your icons and with nagios icon's.

Nagios icon's are in PNG or GIF format (same result with this 2 extensions).
My GD version is : 2.0.1 (deb packages).

For the color change, effectively I could try with your solution, only if I have not yet the red background behind icons

For my source, I'll send you that on the next week, i have to add some debugging infos.

Thanks 4 your help.

That's quite an old GD. I know that even 2.0.33 has problems with transparency/alpha. The left icon looks like the problem I remember - I think I had that with grey+alpha pngs.

Could you post the original image files for your icons please? I'll try them with my (known working) install, and that way we can figure out which of those problems is GD and which is the image format But I think at least part of the problem would be solved by moving to either the latest GD, or the one built into PHP (which does transparency using different code).

That renders fine for me. My PHP is using the bundled GD (not the system one).

If you are going to upgrade with the debian packages, you need to get at least 2.0.34, because 2.0.33 has another different alpha-channel bug

Howie, finally I think I've updated to version 2.0.34
Deb packages :
- libgd2-xpm_2.0.34-1_i386.deb
- php5-gd_5.2.2-2_i386.deb

Phpinfo give always : "GD Version: 2.0 or higher" which isn't very helpful. Is there any Gd function which could return the precise version ?

Thanks.

No, I wish there was, because then check.php could use it

The 2.0.34 in the package name is the best way to tell.

I suppose it's possible that it could be a libpng problem...
