Cacti graph 0 or NaN values

[diskun]

Hi all,

Hope you can help me with a problem on cacti.

Yesterday I started to configure many devices to monitor with Cacti. Right now I have 40 or 41 graphing devices.

But now if I add more devices, problems appears.
First, Cacti doesn't create the .rrd files on new devices. This is because the new device was not in state "Up". I've solved setting the "Downed Device Detection" to "Ping or SNMP Uptime" instead "SNMP Uptime".
Now the graphs of the new devices are created, but show 0 or NaN values.
This is not true because when I run command "snmpwalk", devices returns correct values.

Any idea?

Cacti version: 0.8.8 (Debian repository)
OS: Debian wheezy 7 64-bit

Sorry, my english is poor

I have also run the command:

(67 is hostt's id that fails)

And on that host graph in that time interval (5 minuts). But if I run the command:

Code: Select all

php-q /usr/share/cacti/site/cmd.php

The host with id 67 and 68, not graph.

I do not understand
