I took GD-2.23 frlom CPAN and i install it manually !

When i do "make test", i have :

Code: Select all

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/GD..........Testing using gif support.
t/GD..........ok
        3/12 skipped: various reasons
t/Polyline....Subroutine scale redefined at GD/Polyline.pm line 52.
t/Polyline....ok
All tests successful, 3 subtests skipped.
Files=2, Tests=13,  0 wallclock secs ( 0.23 cusr +  0.05 csys =  0.28 CPU)

How about GD itself then? Is it possible that you don't actually *have* png support? :-)

The other variation that causes a non-obvious message is if you give the BACKGROUND parameter a file that does exist but isn't a png. That will give you a wierd message.

Code: Select all

file weathermap-background.png
should let you know if that is the case.

oh, i verify my png and it was not one :p

but it don't work too :o/

I use my own png created :
BACKGROUND fond.png

when i do file fond.png, i have :
fond.png: PNG image data, 389 x 309, 8-bit/color RGB, non-interlaced


but i have the same error message :'(
Can't locate object method "newFromPng" via package "GD::Image" at ./weathermap line 56, <CONF> line 27.

So working backwards, try this test program:
http://wotsit.thingy.com/haj/gd_wm_test.c

It's just a quick test that loads a file called test-input.png, draws a black box on it and saves it as test-output.png

If that doesn't compile or link, or doesn't work, then I think the problem is your gd lib (not perl, or weathermap). You might also try

Code: Select all

nm -g --defined-only /usr/lib/libgd.so.2
to see if gdImageCreateFromPng is listed in your gd lib.

Hi Howie,
I noticed that the timestamp on the two entries is around 5 minutes apart. Is it possible that your poller.php takes that long to run? You can see this in the SYSTEM STATS lines in the cacti logfile.
i think that is the problem, as i see in the log file that it gets to 296 secs time exceeded, or something like that...
i cannot have cactid 0.8.6c or d run properly for some reason... i get: DB_HOSTNAME: unknown command
DB_USER: unknown command
etc and then the graphs dont get updated :(
any idea, or i should open this in a new topic?

Sounds like a new topic :-) Running multiple threads in 0.8.6c definitely helps with this kind of thing. The words 'DB_HOSTNAME' or 'DB_USER' don't appear anywhere in my 0.8.6c install though, so I guess that would be coming from either a 3rd-party script that no longer works with 0.8.6c or some incorrect text in the config.php?

fix your cacti.conf file those are the typical values that need to be configured on install or new version.

check also cactid.conf

thanks folks... as it is a new topic, i will open one if i still need, after having looked carefully at your answers :)

now, to another issue directly related to weathermap:
as my map gets a little crowded, i am trying to increase the size of the backround, so i can spread more nodes on it. however, it seems that the map stays on the top right corner of the screen, and the icons are very very small.
how do i rescale the icons so that they are bigger?
i want in fact to be able to scroll the screen up and down and sideways if necessary, instead of seeing the whole map at once on the screen...

Thanks,
Harel

The icons shouldn't get smaller... that sounds like your browser is auto-scaling the image. Is this using the HTML generated by weathermap, or just by viewing the image in the browser? At least IE and FireFox will scale the image to fit the window, which would do what you describe - on IE, click on the funny orange square that appears if you hover the mouse over the bottom right corner of the image.

dang i am so lost. get that "Can't locate loadable object for module RRDs in @INC " error

so i have gone back to redo rrd with shared perl install and get this error

make[3]: Entering directory `/home/cacti-install/rrdtool-1.0.49/perl-shared'
make[3]: *** No rule to make target `/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE/EXTERN.h', needed by `RRDs.o'. Stop.
make[3]: Leaving directory `/home/cacti-install/rrdtool-1.0.49/perl-shared'

i know this isnt about that but if anyone has any ideas i sure would appreciate it. i really want to get this working.

that did it :)
in update.sh i had it generated by weathermap, but i changed the background png and not the command in update.sh...

now i have to resolve the cactid thing, but other than that, it is working like a charm.
thank you for the excellent work!

Hi,

I'm having a trouble when I use weathermap, it's working for one link but when I try to add another one I've got the following message:

Code: Select all

Illegal division by zero at ./weathermap line 119.
Here is my weathermap.conf:

Code: Select all

BACKGROUND france.png

KEYPOS 1 520

#     low  high   red green blue
SCALE   1   10    140     0  255

        BANDWIDTH 512000

        NODES   marseille evreux
        TARGET  data/wea_routeur_marseille_traffic_in_106.html
        BANDWITH 512000
and here is the line 119

Code: Select all

119: $outrate=(int(($output{$link}/$maxbytes{$link}+0.005)*100)>100)
? 100:int(($output{$link}/$maxbytes{$link}+0.005)*100);
120: $inrate=(int(($input{$link}/$maxbytes{$link}+0.005)*100)>100) ?
100:int(($input{$link}/$maxbytes{$link}+0.005)*100);
Can somebody help me ?

I tried using rrds and html files. And if i'm using only one of the two links alone it works whatever the link i choose.

And here is the command i'm launching

Code: Select all

./weathermap -- HTML-rendement weathermap.html -- rendement weathermap.png -- config weathermap.conf

BANDWIDTH has a D in it (mars-evx link). The default is zero when there is no setting. In the PHP version, I've made the default is 10K to avoid this one. It's useful to not have to specify bandwidths when you are first laying out the map.
