[oplossing]
Topic mag dicht. de oplossing zat hem in het feit dat de Cron niet liep. De cacti user was aangemaakt maar kon de homedir niet vinden. Na de map /usr/share/cacti aangemaakt te hebben en een chown cacti -R op deze folder te doen, is de cron gaan lopen. Het duurde even maar 3 uur later heb ik nu netjes de grafieken.
[/oplossing]

ik zit met het volgende probleem. Ik heb nadat ik Cacti heb geinstalleerd in een VM zonder problemen. Cacti geinstalleerd op onze monitor server waar onder andere ook nagios draait. Alleen krijg ik op deze bak NAN errors.

wat ik allemaal al heb gedaan:

- de rechten op de RRA en log folder gecontroleerd:

code:

~]# ls -al /var/www/html/cacti/rra
total 536
drwxrwxrwx.  2 cacti apache   4096 Apr 10 12:19 .
drwxr-xr-x. 13  1000 users    4096 Nov 23 20:18 ..

-rwxrwxr-x.  1 cacti apache  94816 Apr 10 17:29 gateway_abboda_traffic_in_9.rrd

-rwxrwxrwx.  1 cacti apache  47992 Apr 10 17:29 localhost_users_6.rrd

de timezone in de php.ini aangepast naar de huidige tijdzone:

code:

~]# cat /etc/php.ini | grep timezone
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone =Europe/Lisbon

services herstart.
logfiles Cacti gecontroleerd.

ik heb de nan erros zowel op een host als op de localhost. Ben een beetje ten einde raad.

versie RRDTOOLS:

 rra]# rrdtool
RRDtool 1.3.8  Copyright 1997-2009 by Tobias Oetiker <tobi@oetiker.ch>
               Compiled Apr  3 2014 13:07:03

Alle hints op de verschillende cacti fora hebben het over rechten issues, maar deze staan goed.

Kan iemand mij hier een zetje in de juiste richting geven?

edit ik zie nu wel in de rrdtool info datapoints terugkomen.
