Device Status = Unknown

fadhil · Post by **fadhil** » Wed May 30, 2007 4:59 am

Hello everyone,

I'm having a problem with cacti on my Red Hat Enterprise Linux ES release 4 (Nahant Update 2). I'm trying to use cacti to monitor a several SNMP-based devices, such as routers and firewalls.
Status of my devices (including Localhost) is always Unknown (this isn't happening in my Debian 4 box), but the SNMP query to the agent is normal (i think). SELinux and firewall is disabled, PHP 5.1.6, net-snmp 5.1.2, mysql 5.0.27, rrdtool 1.2.18.
Because of that, the graph won't display, but on my debian, it's working nicely.

Is there anyone that could help me?

thanks b4.

Can you confirm that the poller is running every 5 minutes?

is it something like:
php <cactipath>/cmd.php?
i'm running it now, but only the localhost is Up (at least there's something Up), and other is Unknown.

Code: Select all

# php cacti/cmd.php
No log handling enabled - turning on stderr logging
Cannot find module (LM-SENSORS-MIB): At line 0 in (none)
05/31/2007 09:23:09 AM - CMDPHP: Poller[0] Time: 0.0743 s, Theads: N/A, Hosts: 2

I didn't resolved it.

I tried to change the owner of cacti folder to user cactiuser and give all rights with chmod 777 in this folder.

Here is the bottom line. You "may" not have a problem.

1) If you are running cmd.php and have not graphs created, the device remains as unknown as it is not tested since it is not polled for anything.
2) If you are running cactid, it is tested always.

Running either cmd.php or poller.php from the command line always helps.

Code: Select all

php -q cmd.php <host_id1> <host_id2>

Code: Select all

php -q poller.php

Try using the chown cacti:cacti (assuming your using cacti as a user) the rra and logs directories. Then use the cacti user to run the cmd.php and poller.php.

Graph reads the rra files if you have different permission it won't show up.

Hope this help...

In my case it was mistake from web tutorial, on how to put job in /etc/cron.d/cacti I copied everything and forgot to remove # in front of:
#*/5 * * * * cacti /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

so it should be
*/5 * * * * cacti /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

now it works

Hi guys!

I solve this issue changing in Settings > Poller ...
In Host Availability Setting Choose Ping to determine if a host is available for polling.

Done problem solved!

This problem is caused by SNMP which not works.
