I'm confused. It's all on the same web page at thingy.com... with instructions, and a tar.gz to download.

My advice would be to install the PHP version on my page (see my sig), as it's easier to install if you don't know what you are doing, but wait for the next version of php-weathermap as it has a couple of important bugfixes. This is ready, and will be available in the next day or so.

You will need the gd extension for PHP to use that version. You can find out if you have this by typing

Code: Select all

php -m

and looking for 'gd' in the list. If you don't have it then you will either need to re-compile php to include it, or install a seperate package or port. It depends on what OS you are using (you didn't say).

You still didn't say what operating system this is... the short answer is "I don't know, and I can't do support for your operating system problems".

I just googled for "how to install php gd module" and found plenty of results, but it depends on your OS! If it uses RPMs or something like that, then it might be very easy, but you didn't say.[/url]

Fedora Core 3 ... Redhat Linux

So I searched google for "installing php gd on fedora", and I got this page

It looks like you need to install the php-gd RPM, if you used Redhat's php RPM.

Ok.
I download your php version. and move as /www/htdocs/weathermap.
Then I run

Code: Select all

php weathermap.php

and i give that result:

[root@cacti-test weathermap]# php weathermap.php
PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php4/gd.so' - /usr/lib/php4/gd.so: cannot open shared object file: No such file or directory in Unknown on line 0

But, my gd.so is located in

/usr/lib/php/extensions/gd.so

Unfortunately i have not gd.dll
SO, clearly problem is about gd.
Now problem is how can configure my php with gd module???
My php version is php-4.3.10.
AFTER THAT ...
I reconfigure my php and make, make install
Then i copy php.ini.dist as php.ini
After that I delete comma in php.ini:

extension=php_gd2.dll

then i run php weathermap.php
I give this:

[root@cacti-test weathermap]# /www/php/bin/php weathermap.php

Warning: fopen(weathermap.conf): failed to open stream: No such file or directory in /www/htdocs/weathermap/Weathermap.class.php on line 685
Couldn't open config file weathermap.conf for reading

is there any suggestion??

I configure gd with

--prefix=/usr/local/gd
..
[root@cacti-test gd]# ls -la
total 24
drwxr-xr-x 5 root root 4096 Jun 16 15:57 .
drwxr-xr-x 18 root root 4096 Jun 16 15:57 ..
drwxr-xr-x 2 root root 4096 Jun 16 15:57 bin
drwxr-xr-x 2 root root 4096 Jun 16 15:57 include
drwxr-xr-x 2 root root 4096 Jun 16 15:57 lib

then
I reconfigure my phpwith

--with-gd=/usr/local/gd

after that

[root@cacti-test gd]# find / -name gd.so
/usr/lib/php/extensions/gd.so

After that:
i copied gd.so to /usr/lib/php4.
Then I run ./weathermap , here is the result:

[root@cacti-test weathermap]# ./weathermap.php

No image (gd) extension was found, or could be loaded. This is required by weathermap.

then I check the my php

Pre-release v0.5 is out now:
http://wotsit.thingy.com/haj/cacti/php-weathermap/

Mainly it's bugfixes including:
Getting the right most-recent value

Windows/RRD bugfixes
other smaller ones

Other new features are the ability to use non-Cacti RRD files, and also to specify decimal bandwidths, both in SCALE and BANDWIDTH.

Tested on RH9 and OS X as usual. Let me know if something's wrong.

Next stop: editor

OK i solve problem about php gd module. and download howie's php weathermap version 5
But another problem is here..
I rename example.conf as weathermap.conf
then I modify something in it.
I run command. And get this:

[root@cacti-test weathermap5]# ./weathermap.php
ERROR: opening 'davutpasa_1a_7206_traffic_in_23.rrd': No such file or directory
ReadData: Link davutpasa_1a_7206-maltepe_2d_7507 had no valid data
ERROR: opening 'data/sync_traffic_in_257.rrd': No such file or directory

Warning: imagecreatefrompng(background.png): failed to open stream: No such file or directory in /www/htdocs/weathermap5/Weathermap.class.php on line 1068
Failed to open background image

As you see there is a "data" directory. where is it?
I think data folder is my rra folder. how can modify this?
And how can I solve background problem?

The 'data' one is easy - you still have an example TARGET line from the example.conf. It is looking for a file that only exists on my Cacti system. Change the TARGET to be the rrd file that you want to use from your system

As for the background, is the background.png file in the same directory as you are running weathermap.php from?

I think I solve some problem like this:
Target is point my rra directory...OK
I copy background from your example to weathermap directory..OK
Last problem !!!
I run:

[root@cacti-test htdocs]# cd weathermap5/
[root@cacti-test weathermap5]# ./weathermap.php

then i go to using my browser:
http://X.X.X.X/weathermap5/weathermap.php
then I get a message:

#!/www/php/bin/php

That's because you shouldn't do that. The weathermap.php is not a normal php web page. If you want to have an HTML page to hold the PNG file, use the --htmloutput commandline option to produce an HTML file as well as the PNG.

It depends.

Yes, if you only want to have the image.

If you want to use the overlib HTML features (when you hold the mousepointer over a link, you see the cacti graph), then you'd need to add in some extra configuration (INFOURL and OVERLIBGRAPH for each link), and use the --htmloutput command-line option to produce an HTML file as well as a PNG. It's more effort, but the result is quite nice.
