PHP Network Weathermap 0.8 (now 0.9)

[ScOp3]

Howie i am having some issues with getting the "OVERLIBGRAPH" working.

My config regarding the link where i want the overlib pic to be looks like this.

Code: Select all

LINK node1144164553-node1144310979
	INFOURL Http://<hostename>/cacti/graph.php?action=zoom&local_graph_id=355&rra_id=1&view_type=
	OVERLIBGRAPH http://<hostename>/cacti/graph_image.php?local_graph_id=355&rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300
	TARGET /srv/www/htdocs/cacti/rra/cisco_450701_traffic_in_359.rrd
	NODES node1144164553 node1144310979

But actually nothing shows up. Clear case of DUH?!?!

Here is the log from cacti.log

This is a strange log!

First, I think you have a problem with cactid - it should run for so long with only 90 hosts. I suggest you disable weathermap and see what is going on with cactid first. 293 seconds is the maximum time it can run for before the next poller cycle. Usually that is a fault.

Second, you seem to be running weathermap twice! Is it possible that you have the $plugins[] = 'weathermap' in two places in your config?

Third, neither of the weathermaps is finishing correctly. Normally there would be a line saying ' Weathermap has left the building' as the last thing it writes to the log. I think that if you had DEBUG on, you would see more there, including a line like 'If this is the last you see, you need to increase your memory_limit in php.ini'. Turn on DEBUG to verify that, but my guess at the moment is to increase memory_limit to something like 32M in php.ini, and restart apache.

With your command line problem... when you don't have an --output line, the weathermap command line program produces a PNG called weathermap.png and no HTML, by default.

Howie,

You are right that my php.ini is out of memory and when I change to 64M, the weathermap successfully generate two png files.

As for the weathermap processes running twice within same polling cycle, it is actually caused by the Cactid timeout issue (exceeding 292s), as a result, the program forks two poller processes and two weathermap prcoesses.

I am still working hard to fix the Cactid timeout problem but thanks for your help.

I unpacked the tar file in the plugins directory, added 'weathermap' to the plugins, but I still don't see a tab or the permissions under user management for weathermap. When I attempt to run weathermap from a command line, I get an error stating
"Can't locate Number/Format.pm in @INC (@INC contains....)
BEGIN failed--compilation aborted...

Any ideas? Perl is in the path and working fine 5.8.
This is a Fedora core 5 system.

Where do you save images that you wish to use as a background? I have created a PNG file and currently have it saved in <cacti_install>/plugins/weathermap/images/ but when I use the editor, and click on Map Properties, no backgrounds are available.

Thanks.

1. It's actually a zip, not a tar
2. You seem to have got some perl from somewhere!!!

There is a perl version, but it's really old now, and will never be updated. If you want to use the Cacti plugin, or any of the nice features, you need php-weathermap-0.8 from the link in my sig.

The editor does not do images. The editor does not do images.

You need to edit the configuration file and add a BACKGROUND line, like:

Code: Select all

BACKGROUND images/yourfile.png

Some day, the editor will do everything that everyone wants, and there will be no need to edit config files by hand, but that day is not today, or even this month.

OK. It obviously threw me as you seem to have added the ability to add background images through the editor which is why I posted here.

The editor isn't finished. The intention is that you would go to Manage Images, and use that to upload images which are then pickable in the ICON and BACKGROUND bits. I didn't want to work through all the security implications of file upload, so as a result, it's not there yet.

Actually, I'll try and get the pick-list part going for the next (0.81) release, so you can pick images you uploaded another way into the images folder. The next major release will have a whole new editor (again), but it'll probably work in a similar way for images.

Sorry for the attitude earlier - having a bad day today.

Okay, that worked... I assumed .zip was windows... Back to configuring the maps and such... Thanks!

[klr0514]

when I am going through the editor, I get this message:
Undefined index: map_linkdefaultbwout in /www/htdocs/cacti/plugins/weathermap/editor.php on line 177

Also, I cannot define background images or html/png output through the editor...

I did vi the editor-config.php file and add the background image.

Any ideas?

Assuming that the image actually exists (try pasting that into a browser), then my guess is that you need 'HTMLSTYLE overlib' at the top of the config file. This isn't the default.

Yup you're guess was a perfect hit. Now it works as designed.

Hey, how about a "cycle" option for the weathermaps we create?

Could just be an option added to the current "cycle" plugin that uses weathermaps instead of graphs (which make more sense anyway).

I was planning to add it as a third 'view mode'. To add it to the Cycle plugin would need the co-operation of whomever the Cycle maintainer is (I don't recall who it is). It would be simple enough to add some hooks into weathermap so that other things can extract the list of maps, and URIs to display them. I want to write a screensaver to do a similar thing and float the results around on my screen, when I have masses of spare time.

My own wish along these lines is that someday Cacti will deal with 'Display Objects' instead of graphs, so that maps and other data can appear in Trees and wherever else graphs appear today. I'd like to be able to make Graph Trees with diagrams, weathermaps and HTML chunks (like explanation) in them, so that a graph tree could be a 'living specification' for a customer.

That would be excellent - how long?!

Yes I think, if I understand what you are saying correctly, we share the same dream. It would increase the flexibility and usefulness of Cacti a 100 fold!
