I currenlty only have two visible maps - one of them being the example "simple.conf" that came with the plugin. Their IDs are now 14 and 15. I'm guessing they increment each time you add or remove them from inside Cacti (MySQL)... knowing that helps.

So, the next question, how is it determined which item (node or link) shows on "top" of the other? Order of appearance in config file? All links go behind all nodes?

Yes - add/remove them, but not move them. You don't really need to add/remove them ever. If you want to have them disabled temporarily then just click on the 'Active' link to disable it.

Nodes on top of links. Both drawn in the order they appear in the config file.

If you have overlapping links, there's a problem in the current version that the overlib areas favour the wrong link (the bottom one). That'll be fixed in the next release.

Okay, need some layout/VIA help needed here:

Code: Select all

I guess it would be helpful if I had a grid with a ruler in the editor, but beyond that, I'm just not sure what turns what which way!

I'm trying to get each link to bend opposite directions (not too much since to the right of both of these I have a third link going to that same "Internet" node and the labels step on each other)...?

I find that less VIA points is better than more, usually.

My trick for placing VIAs is to create a NODE in the editor where you want the VIA to be, then edit the file by hand and take those coordinates and turn the NODE into a VIA for the right link.

For yours, I get OK results (for me anyway) with

Code: Select all

LINK node1144090672-node1144090646
        ARROWSTYLE compact
        BWFONT 3

That's a good trick to know! Any way to change where the labels fall on the arrow? I kind of like:

Code: Select all

VIA 300 200
VIA 310 100

But still, as with your example, the cloud I'm using is overstepping the top label.

Only that maybve your maps are disabled in the management view...

You should get some kind of error in between the two 'iterating/iterated' messages, otherwise.

If you run the SQL from the mysql command-line tool, do you get any results?

Code: Select all

select * from weathermap_maps where active='on'

I am experimenting with the overlibgraph option on the nodes. I want the pop up to display some info about the device in a similar fashion as the monitor plugin. Right now I have it pointing to a static page, but all I see on the overlib popup is a broken graphic and no other info. the overlib works fine on the links. The logs do not indicate anything out of the ordinary.
thanks for your help.

That's because it needs to be an image. Whatever you put in there is put straight into an HTML <IMG SRC="">. When you point it at a static page, your browser tries to figure out what kind of image that is, and gives up.

Right now, you'd need to make some kind of script to produce an image from your information. I think imagemagick might render a text file to a PNG, so that's a possibilty...

hehe. it does! Try something like:

Code: Select all

 convert -trim test.txt public_html/test.png

to get a cropped, black-on-white png of the text in test.txt. I've attached a dummy one. That's almost useable, and it'd be a 10-line shell/awk script to make them.

The real answer is to allow embedable HTML in the overlib stuff, but that means having some kind of HTTP client in weathermap, as well as being sure that the HTML fragments that were fetched are valid. Most things will produce a complete page, which isn't valid.

cool! I'm going to try another approach... I will take a snapshot of the html page and save it as an image...

here is the result I was looking for

knobdy · Post by **knobdy** » Tue Apr 04, 2006 4:14 pm

How'd you do it? Can it be done on the fly/on demand? Via a script?

I'd just like what I currently have being displayed at the top of my graph views - system info...

Hi Howie,

I would like to thank you for the tool.
I'm having a problem with the png file.
I've tried testing your addon with 3 network equipments I'm
monitoring and it works well.
I've decided to add all my core network equipments, around
20 of 'em now the weather_15.png is generated blank. The size is about
33k, but when I manually run ./weathermap it generates the whole png.

What seems to be the problem?

Thanks.

What does the cacti log say? What about if you turn DEBUG on for one poller cycle?

(hehe. I can think I need a macro button to type that, like lvm must have...

)

Ah, it was fine with my icons

If it is though, try using one of the node offsets, like SW or SE, so that the arrow starts from the edge. The labels are always 25% and 75% of the way along the link, unfortunately. You can change where 0 and 100% appear, however, with those offsets. You'd need a squarish cloud to stop it looking funny though.

I'm thinking that I'll probably add a pixel offset sometime soon, like LABELOFFSET has, so that you can fine-tune it for non-square nodes.
