NaN/0 values on Linksys Switch

Post by absynth »

I have upgraded my cacti installation to 0.8.6i, and tried to recache whatever possible - even went through the whole "NaN debugging" process to no avail. I have a 24-port linksys GBit switch that refuses to deliver data to ONE SPECIFIC cacti installation. It works on a testing machine set up by one of my friends, but not in our production environment.

I have absolutely no clue what I am doing differently on our production box that causes this one host to constantly fail.

I have PHP 4.4.4 without SNMP extension compiled in, net-snmp 5.1.2 and I'm using cactid. This is what I get by polling manually:

Code: Select all

management:/www/cacti$ /usr/local/cactid/bin/cactid  -f 191 -l 191 --verbosity=9 --snmponly -S

The weird thing:

a) the "did not perform snmp due to settings" since the host is up and of course also enabled in cacti, and pinging it was obviously successful
b) the "timeout detected" message is obviously totally idiotic, since the whole poll does not take longer than 550 ms (see last line of output) and there can hardly be a multiple 1000ms timeout be hit.

Any ideas?

With Cactid, goto the Poller tab under Settings and set the MAX OID Per Get Request to 4 or so and see if the problem goes away. You may be overloading your inexpensive Cisco switch.

No, that is definitely not the problem. I think that for some weird reason cacti is accessing the wrong OIDs, since a manual snmpwalk on the device doesn't yield any usable results either on the OIDs that were in my paste.

What really bugs me is that another installation of cacti (on a machine I cannot control) has no problem whatsoever, but uses cmd.php for polling. So, I have basically two possible conclusions:

a) Is there anything wrong with the libsnmp version I'm using? /usr/lib/libnetsnmp.so.5 from Debian Sarge
b) Is there any possibility for differences, e.g. in MIB files that could cause the problem?

If you are talking about this:
Host[191] PING Result: UDP: Host is Alive

Host[191] SNMP Result: SNMP not performed due to setting or ping result
That host is alive I'm pretty sure due to the UDP ping result.

I know that the host is alive. Still, cacti does not get any decent values where other snmp software (including snmpwalk) does. So I guess cacti has the wrong OIDs. Any way to fix this?
