PHP Network Weathermap 0.8 (now 0.9)

You need to add a TITLEPOS line. The default TITLEPOS is -1,-1, which is 'off'. This is because the TITLE existed a few versions ago, just to be used by the editor, and it's only in 0.8 that you can show it on-screen, so I defaulted it to not shown, so as not to break any existing maps.

Interesting, it won't take a 0 position, but:

Code: Select all

TITLEPOS 1 20

works...

OK. That's tweaked to allow 0 in the dev version.

I have some of my bottom level INFOURLs set to be "telnet host" in version 7, not under cacti control. Works great. In fact, depending on the host, some are set to putty (ssh) or https, or whatever.

Under V8, and cacti control, with a config like this:

INFOURL telnet:192.168.2.190

I get a click button more like this:

http://myhost/mycacti/weathermap/telnet:192.168.2.190, which obviously wont work....

Is there any way to override the prepended stuff? I expect that it is part of the system security - but, still, a pain!

I just install weathermap 0.8beta4 in my Cacti(0.86h) in Fedora 4 as a plugin. The Weathermap can successfully generated a png file and put in in output folder. However, when I log on to cacti and under the weathermap tab, cacti complain "(thumbnail for map 4 not created yet)" but I can see the png file created and updated in the output folder.

I would be appreciated if anyone can tell me what's wrong with my installation ?

Nothing is prepended. That would be done by the browser because it thinks that telnet:blah.blah is a relative link. I'm pretty sure it should really be telnet://blah.blah.com/ - that certainly works for me in Safari.

ssh:// also works for me, incidentally.

You should get *two* images for each map - a thumbnail and a fullsize image. It sounds like the thumbnail isn't being created for some reason. A work-around would be to change the weathermap view style to 'Full Images' in the Misc section of Cacti's settings. That would not try and use thumbnails then.

Do you get any error in the Apache error_log or Cacti's log?

It sounds like the imagecopyresampled() function doesn't exist in your php/gd installation. I have FC4 on one of my desktop systems though, and I do get thumbnails with no trouble.

Hi folks!
I want to upload my images, i have exported then in visio 2003, in attachment to yours.

You need to convert these images from JPEG to PNG, so you can use them for ICON lines in NODEs. Try something like
Image Converter to do that.

They also look like they are probably copyright Microsoft (unless you are a good artist!) so I would say don't post them on the forum!

I didn't get any error from Cacti log or Apache. However, I do find out the png file generated has no content. Is it possible because of configuration ? If the configuration is incorrect, does weathermap still generate png file except html ?

Thanks a lot

Has no content as in blank, or 0 bytes?

Most configuration errors cause an error in the Cacti log, and usually they only affect the node or link that it is within. You would have to have an error in ALL the nodes to get a blank map... (that would make the links break too, because the nodes were ignored).

You may want to turn DEBUG on for one poller cycle in Cacti, and look at the logs then. You might also try using the command-line tool from the plugins/weathermap directory:

Code: Select all

php ./weathermap --config configs/yourmap.conf

and if you don't get any errors:

Code: Select all

php ./weathermap --config configs/yourmap.conf --debug

If there's still nothing, then I'd like a copy of your config, please (either PM me or e-mail)

You should still get two PNG files, though: weathermap_1.png and weathermap_thumb_1.png

Howie,

I am able to generate png file shows the network map with --output option. However, when I execute the php ./weathermap command without the --output option, I can't see any file generates inside the weathermap folder or the output folder. There is also no error complained from the debug.

Best Regards

Just put them in the images folder and edit you're conf file. AFAIK you can't assign the pics in the editor yet.

Code: Select all

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.
