Getting cacti to gather network traffic stats

[lga]

Just wanted to post a quick reply to thank rony for the personal help in debugging my cacti install. Stupid user error, fixed.

Thanks again.

How do you fix your error?? To do to work interfaces polling

His error was he edited the lib/snmp.php file and changes something he wasn't suppose to. So, the result was SNMPv1 worked, but SNMPv2 did not.

lga, I don't know what is wrong, but if I had to guess, I would say your traffic templates are screwed up. When you attempt to make graphs, they come up, right? But the never update?

I think I found the error...

In table "snmp_query" the field "data_input_id" for the id 1 "SNMP - Interface Statistic" was equal to "86"! But data_input_id 86 doesn't exists in table "data_input". I refixed this value to "2" as in the default cacti.sql ...
It seems work ... I let to run until tomorrow to see the result ...

Thks,

Lionel.

I didn't change anything in /lib/snmp.php. I checked the value un the cacti database but it's good. The polling on network interfaces is still a failure!

here is my verbose debugging when I add the data query "SNMP - Interface Statistics" :

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/usr/share/cacti/site/resource/snmp_queries/interface.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1'
+ No SNMP data returned
+ Found data query XML file at '/usr/share/cacti/site/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/usr/share/cacti/site/resource/snmp_queries/interface.xml'

Hi,

You've maybe the same problem that me. Check your table "snmp_query".
Verify if the field "data_input_id" fixed to "2". the value "2" of "data_input_id" is in fact "Get SNMP Data (Indexed)".

That was my problem. Since I've modified this, all work right

I just checked it one more time and the value is well fixed.

Another idea?

Thanks,

Same problemm for me , checked everything but impossible to get Traffic graphs displayed.

cacti 0.8.6c-7sarge2
NET-SNMP version: 5.1.2

[fata51]

check your snmp version specified in cacti (net-snmp/ucd-snmp)

I just changed to NET SNMP 5.x et it works now...
