WeatherMap Not Updating

humanlock · Post by **humanlock** » Fri Nov 13, 2009 3:46 am

Hi,

First, I apologize for my poor english, it is not my native language.

I have just updated and installed Cacti with WeatherMap.

I have start from a running Linux Box Debian Etch,

Then, I update it to Debian Lenny, remove the Cacti installed by apt-get, and install it manually from tar.

Every things works fine, Traffic from my router, and switch are correctly polled.

I've installed then the PA 2.5 and WeatherMap Plugin.

My poller is executed every 5 min, WeatherMap at the same time.

All the graph are nice no problem.

Now here is my trouble. Maps are generated without data.

So, I have modified some things for permission and use www-data as cacti users, change ownership of directory and try with the Forbiden Button.

It worked, but sometimes not. And I realise that the problem is present only If I tried to update map just after the poller.

If I update 2 min after, no problem. It's like data are not complete when you launch map generation just after the poller.

And, the best for the end, the CPU USAGE is not affected by this problem, onlye the network traffic. My Label are changing color correctly.

Do you have experienced any similar issue ?

Stop using the Rebuild Now option. Cacti will update the map by itself if your use the weathermap plugin.

I aren't using it since severals days, I have purge the directory (remove all maps) and waiting.

I have no data for the link, but the CPU label is working.

Hello!

Just a quick heads up from someone who've used a fair amount of time trying to figure out the exact same thing on a Debian 5 (lenny) system: Why does the "Recalculate now" button work, but not when it is updated from the poller/cli?

Actually I don't have an answer to my own question .... 'cause I really don't know why Debian won't draw all the right link colors and other nifty things in my Weathermaps when it is not being updated from the web gui.

I've upgraded to the latest versions of php5 and php5-gd from http://www.dotdeb.org. I've installed the newest gd-lib (2.0.36) and I've run the script from Howie's weathermap plugin "check.php" - and it all says the same in both cli and via www: ALL OK! But it just doesn't work from the cli!

The way I've done this in Debian is to set the weathermap to never update the maps under "Settings" and instead i've created a new entry in my /etc/cron.d/cacti:

Code: Select all

*/5 * * * * /usr/bin/curl http://localhost/cacti/plugins/weathermap/weathermap-cacti-rebuild.php

This way the maps are being redrawn every 5 minutes via the gd-lib from the web-gui (mod_php) and not the non-working gd-lib from cli.

Off course you have to fix the above URL if it doesn't match your cacti's installation.

I hope this helps anyone that faced the same problem as I did....

Regards,
Tommy

You need to edit your file weathermap-cacti-rebuild.php in the weathermap directory. In the file you need to set the correct $cacti_base according to your installation.

Mine is:

Code: Select all

$cacti_base = "/usr/share/cacti/site/";

You probably can't see any difference in the output between CLI and GUI. At least I couldn't.

This sounds like you just need to check the cacti.log - if it's not collecting data, you'll be getting errors about that of some kind.

I get the same output when run from GUI and CLI. As i can see they both collect the data from the rrd-files correct.
