[SOLVED]Some graphs without values

[firores]

Hello, i have a problem with two graphs. The graphs are displaying but values are always at 0

But in the log files, we can see that cacti manage to retrieve data :

11/14/2009 01:46:02 AM - POLLER: Poller[0] CACTI2RRD: /usr/bin/rrdtool update /var/www/cacti/rra/localhost_traffic_in_34.rrd --template traffic_in:traffic_out 1258159561:589954978:2936321286

It suddently appened, and i don't know why.

Thank you for you help.


edit : It's only those 2 graphs. All the other are displaying correctly.

hi folks,
im new on this board, and it appears I have the same problem as the original poster of this topic.

im running cacti 0.8.7 on CEntos 5.4
have 3 hosts in total, but only one shows the graphs normally (windows7)

the other two show empty graphs (1 ubuntu 9.10 and one centos 5.4).

debug on one of the graphs on the problematic hosts:

Code: Select all

RRDTool Command:

/usr/bin/rrdtool graph - \

RRDTool Says:

OK

from the shell on the cacti server:

Code: Select all

11/14/2009 08:53:14 PM - CMDPHP: Poller[0] Host[8] DS[97] CMD: perl /var/www/html/cacti/scripts/unix_processes.pl, output: 103
11/14/2009 08:53:14 PM - CMDPHP: Poller[0] Host[8] DS[96] CMD: perl /var/www/html/cacti/scripts/unix_users.pl , output: 1

from what I understand, the data has been gathered succefully, yet the graphs are empty.

please help!!

thanks,
K.

ok, i think I got it fixed.

what I did was to install the libtool package.

[firores]

tried to install libtool, but the problem is still here.

edit : problem solved. I just restarted the server.

i had empty graphs too, my problem was the data in my rrd was with timestamp of a few days ago, while the graph is trying to plot data of the last 24 hours
