Getting cacti to gather network traffic stats

[fsd]

I am running cacti 0.8.6f on ubuntu (breezy badger), and running it on localhost to gather assorted system stats (mem usage, hdd usage etc) and was wanting to use it to get graphs on the bandwidth usage for eth0.

The problem is involved in actually retrieving the data, when i try to add the data query to the host, it works ok, however receives no data. When i run a verbose query, i get the following:

Code: Select all

Data Query Debug Information
+ 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'
+ Found data query XML file at '/usr/share/cacti/site/resource/snmp_queries/interface.xml'

Any ideas?

Yah, you need to be running snmpd on the box, so that you can graph interface statistics.

Also, moved to Linux

[fsd]

snmpd is running, all other info is retrieved without any issues so snmpd itself is working. have tried stopping/restarting snmpd with no luck

[fsd]

Brand new manual install of 0.8.6g does the exact same thing. Have tried different snmp versions/rrdtool etc, to no effect.

Have you set the community correctly?

When you view the device, does it give you any snmp information at the top?

Hello,

I have the same problem for graphing network stats of a computer with a debian sarge. SNMP informations are well displayed. Informations about processes, users, memory, disk space are well graphed. But no informations about network interface are collected...

is it a bug?

thanks

Same thing with 0.8.6g install on Solaris 9. All other default snmp graphs appear to be functioning. Snmp is installed and running on the box (mrtg is working, snmpwalk functions correctly at the command line). Full paths for snmpwalk/snmpget are referenced in the settings.

Thoughts?

Brand new manual install of 0.8.6g does the exact same thing. Have tried different snmp versions/rrdtool etc, to no effect.

Please select Verbose Query from the Device Screen and post the results. Do a snmpwalk from command line for that host and post the results as well (e.g. snmpwalk -c xxx -v 1 <host> interface)

Here's some more info (verbose query and snmpwalk) from my solaris install:

I've the same problem on RHEL4 and Debian with Cacti 0.8.6g and cactid 0.8.6f-1.
All works but not interface check and traffic.
By example, I see SNMP information of routers but not the interfaces of routers.

Bug ?

Ok, I got rid of the "SNMP Error" on the top of my page by removing execute permission restrictions on the snmp binaries. I'm not sure why I was getting those errors (binaries run as apache user?).

I'm still getting the "No SNMP data returned" issue when trying to snmp queries on my interfaces within cacti.

[rony]

Um, did you update snmpwalk's permissions?

[tonyurban]

Yes, I did, for all of my snmp binaries. That's what cured the "SNMP Error" that was displaying at the top of the page. However, the other error is still present (verbose query is failing with error as above).

[rony]

What are the ulimits for the apache user?

Do you have IM, I will be home in about 1 hours, we can attempt to work on this issue.

[rony]

Was an SNMP version issue..
