can't monitor host through SNMP cause status is Unknown

[silr]

Hey all!

I have installed Cacti 0.8.6d on a Fedora core 3 host, but when I try to monitor remote hosts throught SNMP their status becomes Unknown
{
An example is

LocalSNMP Unknown 192.168.0.112 0 0 100%

The information for the remote host is the following

LocalSNMP (192.168.0.112)
SNMP Information
System: Linux s112.xanadu 2.6.9-1.667 #1 Tue Nov 2 14:41:25 EST 2004 i686
Uptime: 321907
Hostname: s112.xanadu

SNMP Options public /version 1 / 161 / 500
Associated Data Queries
1) SNMP - Get Processor Information (Verbose Query) Uptime Goes Backwards Success [0 Items, 0 Rows]
2) SNMP - Interface Statistics (Verbose Query) Uptime Goes Backwards Success [0 Items, 0 Rows]
}


even though snmpd is running on the remote host and if I use snmpwalk I get

[root@s110 ~]# snmpwalk -v 1 -c public 192.168.0.112

Here is the output of the debug. It seems OK to me.

Any help or pointers would be much appreciated.

Thanks in advance,

Double check you paths, that is not a normal log, especially the path to PHP.

Something is up with you snmpd, restart it. A walk of the tree should yeild more than that. Otherwise, please review you snmpd.conf.

[silr]

I've checked the path for the PHP binary. It's the one stated in Cacti Settings /usr/bin/php).

And the snmpd.conf file (attached) it's the one generated in the setup process.

I'm having the same problem. Can anyone shed some light on this?

[oxy]

same problem, it makes me crazy !!!

[rdilallo]

I had the same problem. I made sure that the community string was properly defined in the settings. I also restarted snmpd I can't explain why this occurs, but that seemed to fix my problem.

FC4 with all the latest updates running.

[mwestern]

it's not something like secure linux that is enabled by default with FC4? i had to turn it off completely with FC3 to get cacti to run.

[rdilallo]

I always turn that off with my installation, however, I was referring to a resolution for the random "unknown" error.

[TheWitness]

Unknown errors are caused when you use cmd.php and either don't have graph/data source items created in the poller cache, or you have a messed up graph/data source/data input method collection that is causing cacti not to place items in the poller cache correctly.

When did you say this started?
