Hi Team!

I've installed Cacti Version 0.8.6j on my Debian/Sparc.

I can graph locahost resources fine, but i can't graph a snmp (cisco) device.

Cacti can see snmp information and router interfaces, so I assume that snmp is working fine on the system.

But the graphs aren't generated, due to a device down or unknown status.

Code: Select all

RRDTool Says:

ERROR: opening '/var/www/cacti-0.8.6j/rra/roul01_traffic_in_12.rrd': No such file or directory
I've already changed my polling method from just SNMP to SNMP+PING, but nothig happends :(

Also changed the user running the poller.php

Code: Select all

# CACTI POLLER
*/5 * * * * root /var/www/cacti/poller.php > /dev/null 2>&1
Really, I don't know what do :(

I used cacti before, but never had this problem. It just worked from the begining of the installation :)

Please, help :)

Here we can see this devide configuration in cacti, and how it's reachable by snmp.

Hi

usually a device is marked "unknown" until next time the poller is run.

Can you run the poller by hand ?

Also, are you sure you want to run the poller as root ?

Hi fmangeant,

Thanks for your fast response!


I can run the poller by hand. Here's the result:

Code: Select all

BUE-LAB07:~# php /var/www/cacti/poller.php

Warning: pclose(): 48 is not a valid stream resource in /var/www/cacti-0.8.6j/lib/rrd.php on line 48
BUE-LAB07:~#
Besides, i leaved "root" in crontab as i read somewere that it's needed when the poller is configured as SNMP+PING. I'm going to change it to "www-data" again.

Any suggest?

BRegards.-

Hi Reinhard,

I'm following the "NaN Debbuging"

1. Check Cacti Log File

My log file has 500K+... so here's a 1 cycle polling log in debug mode:

I would think that RRDtool is crashing. What version are your running of RRDtool and what version of PHP? How much memory in PHP.INI for Scripts. Make sure it is at least 64mbytes.
