hi,

I chowned all my cacti web directory plus rras to user and group www-data, but i still have the same problem :

The fix will be in lib/datasources/WeatherMapDataSource_rrd.php

on line 266 and 270 (roughly), change the preg_match() lines to say

/^\-?\d+(,\.)?\d*e?[+-]?\d*:?$/i

instead of
/^\-?\d+\.?\d*e?[+-]?\d*:?$/i

so that it will match a , or a .

I do not know if it is a problem, but i ind the line only once, at line 243.

i tried to run it manually on command line, with version 0.9a and 0.9b, with and without code modification, and it is still the same problem

what is the difference when i run it through cacti site ?

tomate · Post by **tomate** » Mon Dec 01, 2008 4:35 am

another point is that with this :
/^\-?\d+(,\.)?\d*e?[+-]?\d*:?$/i

i ve got the same problem when i use "Recalculate all Maps"

You could also try the current subversion copy of this file, which already has this 'fix' applied... see if it helps you.

it still works with recalculate button, but still the same problem

what exactly is the difference between command line/poller and the recalculate button ?

i upgraded my cacti with debian package, version 0.8.7b-2.1, and plugin arch too, in version 2.2
still the same

Only the user it runs as.

If you are using the actual command-line weathermap script and not the poller, then it's possible that it's using a different rrdtool - the rrdtool path is in the script itself, whereas Recalc Now and the poller both use Cacti's path to rrdtool.

my rrdtool is in /usr/bin/rrdtool
weathermap uses /usr/local/bin/rrdtool, that is a symlink to /usr/bin/rrdtool

i have just tested on another installation : new installation of apache2, mysql5, php5, cacti 0.8.7b-2.1
all debian packages

only 1 host and 1 graph in cacti, i am waiting for first results

as you can see, there is still ',' instead of '.'

and i use your new WeatherMapDataSource_rrd.php
line 364 :

ok, i really think the problem comes from the regexp
with this '/^\-?\d+[,\.]?\d*e?[+-]?\d*:?$/i'
i have some weird results but results are not invalid nor 0 !
i have to learn more about perl regexp

I've given up trying to follow what you've changed.

It seems that you have a system where rrdtool's output changes without you doing anything.

it seems that the regexp does not match for the moment when there is ','
but i do not know how to fix it

i tried with a third new installation from cacti package, not debian one and the result is the same

so you think i should try to install rrdtool from sources ?
