Weathermap Map Refresh

[mercolino]

I installed weathermap, and its working. I create a Map and it's working only when your recalculate the maps with the button in the Console menu weathermap. But when you enter in the weathermap tab, the map is not refreshing automatically. I am running out of ideas.

Thanks for your help

If you used the recalculate button, then probably the permissions are wrong on the files in the output/ directory. Check the cacti.log file, and it will tell you. chown -R cactiuser output/ will probably fix it. If things ever stop working, there will almost always be some clue in the cacti.log.

I changed the permissions in the Output directory and still I get nothing, in the cacti.log thgere are no references about weather map, only if I activate DEBUG, then there are some references about SQL reading maps in some Tables. Even when I run the command php ./weathermap, no maps are generated in the output directory. i don't know if there is a way where I can tell weathermap to find the configs file and to specify the output folder. Anyway, I edited weathermap and I uncommented the line about debugging, and when I run the script the output is:

The 'weathermap' script only runs one config at a time. You can specify it on the command line, but the default is weathermap.conf in the current directory. It would have created a 'weathermap.png' file in the current directory. You don't need to edit the script to use debug mode, just add --debug to the end. There are lots of options, which are in the Command-Line Reference in the manual.

Anyway, that tells you that most of weathermap is probably working.

Nothing at all in the Cacti logs? You should at least get a "WEATHERMAP Starting" line, even if there are no maps and even in normal logging, unless you have turned on the 'quiet mode' in the Weathermap options (Settings..Misc in Cacti).

I found the problem, finally the errors was shown in the cacti.log and there was an error about permissions in a sessions folder in php.

I am sending my first map.

Cool

You might want to look at the LABELOFFSET command in the manual though - you can adjust those labels so that they don't all overlap so much.

How can i see the refresh rate of weathermap?
It only makes the refresh, when i click on the refresh buton of my browser...

I already went to the "misc" in cacti, and put th refresh time, and refresh interval in 5sec..

Thks.

The refresh time in misc is for the map cycling mode in Weathermap (choose 'automatically cycle' in the top corner).

On the normal or thumbnail displays, Weathermap uses the same refresh time as Cacti itself, which is 300 seconds (5 minutes). I thought you could change that somewhere in the Cacti settings, but I don't see it right now.

None of those things affect when the weathermap is actually recalculated, which is once every poller cycle - usually 5 minutes.

Hello mercolino, I have the same problem that you had.

Can you tell me how can you resolve precisely this problem ?
What kind of permissions errors about php ?

Thanks for your help
