what could be causing it? thanks for the help.

Does the regular plugin part produce maps OK? The error is caused by a missing function in your GD library. I would have thought that the map-generation side of things would fail too. Try adding (say) the example.conf file to your map list, and see if it is generated. If it isn't (after 5-10 minutes), then have a look in your cacti.log. The short version is that you probably need to upgrade your GD library, and possibly recompile your PHP to use the new library.

what do you mean by regular plugin part? my cacti is installed in win2k server. i don't think there is a gd library there. thanks for the reply

OK. Read the installation guide for Weathermap. Follow through the part about adding an example map, and see if that works. You should be able to get a map to appear under the Weathermap tab in Cacti. If that doesn't work, check your cacti.log file for lines that contain "WEATHERMAP", to see if there are any errors to explain why.

You will need the GD PHP module for weathermap to work though. You can find out if it's installed by running php -m from a command prompt. Look for 'gd' in the list of modules that it produces. You might need a newer version of gd to get the createimagetruecolor() function, too.

got this from cacti log

Available in your command-line php program. Please check the output from 'php -i' and your 'php.ini' to be sure!
IMPORTANT: Just because mod_php and php_info() shows gd in a webpage, it doesn't mean it's

No image (gd) extension is loaded. This is required by weathermap.

Hi,
I Install Plugin arch.
Then Install weathermap as plugin
Changed permission weathermap directory as nobody:nobody ( inc. all subfolders and files)
I set cacti log as DEBUG.
I set some config file in configs. dir.
But still there is no graph in weathermap tab.
My cacti log file says that:

09/25/2006 11:11:35 AM - WEATHERMAP: Poller[0] Weathermap 0.82 in da house
09/25/2006 11:11:35 AM - WEATHERMAP: Poller[0] Engaging Weathermap DEBUG mode
09/25/2006 11:11:35 AM - WEATHERMAP: Poller[0] Iterating all maps.
09/25/2006 11:11:35 AM - WEATHERMAP: Poller[0] Iterated all 0 maps.
09/25/2006 11:11:35 AM - WEATHERMAP: Poller[0] Weathermap has left the building

What is the problem you think?

I think the problem is that you didn't go into the Manage.. Weathermaps page and add the config files to the list there.

Yes.
U r right. But still I have one problem.
I have three config file. But I can see only two files when I want to add.
I check the permission of this file there is no difference.

What is the name of the file? I don't think it will treat any files differently, but just in case...

name is backbone.conf

TFC · Post by **TFC** » Mon Sep 25, 2006 5:11 am

I solve it.
When I clear the poller cache, I can see that config file.

I dont know how but when I did this everything is ok

Another question is:
I have two links between two nodes.
But I cant see both links at the same time.
I use VIA parameter.
Here is the config:

Code: Select all

NODE MTP-CR-02
	LABEL MTP-CR-02
	POSITION 640 464

NODE SGT-CR-02 
	LABEL SGT-CR-02 
	POSITION 640 600

LINK MTP-CR-02-SGT-CR-02 
	INFOURL http://10.200.167.214/cacti/graph.php?local_graph_id=3177&rra_id=all
	OVERLIBGRAPH http://10.200.167.214/cacti/graph_image.php?local_graph_id=3177&rra_id=1&graph_nolegend=true&graph_height=100&graph_width=300
	TARGET /www/htdocs/cacti/rra/mtpcr02_traffic_in_3633.rrd
	VIA 600 535
	WIDTH 5
	NODES MTP-CR-02 SGT-CR-02 

	
LINK MTP-CR-02-SGT-CR-02
	INFOURL http://10.200.167.214/cacti/graph.php?rra_id=all&local_graph_id=3307
	OVERLIBGRAPH http://10.200.167.214/cacti/graph_image.php?local_graph_id=3307&rra_id=1&graph_nolegend=true&graph_height=100&graph_width=300
	TARGET /www/htdocs/cacti/rra/mtpcr02_traffic_in_3780.rrd
	VIA 680 535
	WIDTH 5
	NODES MTP-CR-02.1 SGT-CR-02

What is wrong ?
I always see that one:

Code: Select all

LINK MTP-CR-02-SGT-CR-02 
	INFOURL http://10.200.167.214/cacti/graph.php?local_graph_id=3177&rra_id=all
	OVERLIBGRAPH http://10.200.167.214/cacti/graph_image.php?local_graph_id=3177&rra_id=1&graph_nolegend=true&graph_height=100&graph_width=300
	TARGET /www/htdocs/cacti/rra/mtpcr02_traffic_in_3633.rrd
	VIA 600 535
	WIDTH 5
	NODES MTP-CR-02 SGT-CR-02

Both the LINKs have the same name. Rename one or both of them (e.g. MTP-CR-02-SGT-CR-02-a and MTP-CR-02-SGT-CR-02-b). Otherwise the second one just overwrites the first one.
