Weathermap not updating

rajjinator · Post by **rajjinator** » Fri Jun 05, 2009 8:06 am

Hi have a CactiEZ server on running on VMWARE ESX server. I have recently expanded the disk using VMKFSTOOLS -X and extended the primary partition using GParted to give it the extra space.

Since doing this weathermap will not update (created date does not change), However the main cacti graphs are still being updated fine.

any idea what is causing the weathermap to not update?

when pressing the "recalculate all maps now" button it gives the following errors...

Warning: imagepng() [function.imagepng]: Unable to open '/var/www/html/plugins/weathermap/output/41601a837f84e4805dc3.png' for writing in /var/www/html/plugins/weathermap/Weathermap.class.php on line 2472

ok, i've altered the permissions on the output directory and now the "recalculate all maps now" button has worked. and the map updated, but it still does not automatically update every minute like it used to?

anyone?

Read the GIGANTIC WARNING about using Recalculate Now.

You are breaking the permissions every time you press it.

Do I need to add something else to that warning? What does it need to say to make it clearer what the problem is?

I have the same issue. The maps will refresh if I press the forbidden update button, but do nothing on their own. I have verified the permissions, and have NO ERRORS in the log files.
If it works with the recalculate now, How do I get it to work on its own?

What are the permissions of the output directory and the files in it?
Who is the owner of the output directory and the files in it?

What user does the poller run as?

What *does* appear in the log?

Here's output from Cacti log

Do you have the Weathermap 'quiet logging' turned on? I would expect to see at least 2 lines in the log (WEATHERMAP STATS and WEATHERMAP START) even with no maps configured... With DEBUG logging on, you should see a few dozen lines of logs per poller cycle, even without maps configured.

I don't think it's a permission issue either.

Did anything special happen at 16:06? (e.g. cacti upgrade, install other plugin, etc)

Does Weathermap show up in the Plugin Management page? Does it say 'Old Architecture (Running)'?

Quiet Logging is set to Chatty

16:06 is when I pressed the forbidden button to manually update the weathermap.

Weathermap does NOT show up in the plugin management page.
It does show up in the Updates page though.

Re-installed Cacti, plugin architecture, and several plugins.

Weathermap is working properly now.

Weathermap shows up in the Plugin Management page. It says 'Old Architecture (Running)'.
