Are your wea*.html files getting updated?

[madjeff]

So, is anyone else having trouble getting the script to run in cron, or is it just me?

Well, no, but I changed the values in the html file 'by hand', so this shouldnt be the problem..

I got 104 rrd-files in my /rra dir, but the script posted by David R. only makes 57 .html files. Anyone know why?

Hi

I've tried running cacti2weathermap.pl and the weathermap.pl scripts and have the html files generated, however my .png file appears broken. I cant open it.

I'm running windows 2000 and cacti 0.8.6c No perl errors, so I'm a little confused. Is this a basic windows/linux compatibility thing? Do I need to do something imaginative with GD?

Any thoughts greatfully received.

Cheers

Ross

I'm in the exact same boat as Rossco... Win2K, 0.8.6c, HTML's generated fine, no Perl errors... It creates a .png output file that won't open. The output file is oddly 11k smaller than the original, so it's evidently not completing the file.

Can't seem to get the -v debug switch to display anything more than "Network Wearthermap v1.1.1 - http://netmon.grnet.gr/weathermap/"

Was just trying to start simple with two sites and one link. I can paste the HTTP TARGET link to the data file into a browser and it comes up fine (and has in & out data like it should).

My weathermap.conf file:

...and the config section of the weathermap file:

If I had to guess, I would say that I screwed up the in GD Graphics Library since I wasn't quiiiiiiite sure exactly what to do with it on a Windows system.

Anyone got this to run from a Windows box yet?

Thanks,
Jason

The output file is oddly 11k smaller than the original, so it's evidently not completing the file.

Try adding

Code: Select all

binmode(PNG);

directly after the

Code: Select all

open(PNG,">$OUTPUT")||die("$OUTPUT: $!\n");

line.

Windows Perl opens files in ascii mode by default, if I remember correctly, which will silently break any binary file saved (like a PNG).

Hi,

what do you get when you run the script by hand in debug mod (removing the comment line in the script to see the output when a rrd file is not treated.

Regarding the cron proble I had an issue also on RH ES, when I did try to get the script run evry 5 minutes, don't know why, putting it to 3, worked.... weird.
Heres' my cron (located in cron.d directory):

Code: Select all

[admin@webutil admin]$ cat /etc/cron.d/weathermap

*/3 * * * * apache ( /usr/local/bin/c2weather 2>&1 && /usr/local/bin/weathermap -c /usr/local/etc/weathermap.conf &>/dev/null )

(c2weather is the script)

David.

ps: first remove all the wea_* files

[Rossco]

Howie, you da man!

Graphics now outputting correctly - links dont work, but I'm certain thats my mistake.

Thanks for your help.

Kind Regards

Rossco

Make sure you have a directory inside your graphs directory called "weatherm". Create it if not. By default, graphs go to wherever/cacti/graphs/weatherm/

Good luck!

I can run cacti2weathermap.pl from the command line and it creates the files perfectly. But when I run it via cron, it doesn't create/update the files. Any idea what might be causing this?

Sorry, another "bump" for help. I'm just getting back to this after the long weekend, and I'm still having trouble getting this to run in cron.

What use do you run the cron job as? Is it the same use that owns the directory and the files that you are trying to create?

If you tested it as root, then added a cron job for your cactiuser for example, then it will indeed fail. In that case:

Code: Select all

chown -R cactiuser /var/www/directory_with_weathermap_data

ought to fix it for you.
