Goto Graph Management and choose the broken graph. In the uper right corner there should be "Turn on Graph Debugging Mode".
Click on this on and post the result here.

If you click on verbose query, any data get returned?

validate with snmpwalk if the interface are working.

[rmuhammadali]

Dear BSOD2600,

Attached is the result of the verbose query after clicking SNMP - Interface Statistics debugging.

Dear All,
I captured the windows machine it will give the interface statistics without any problem. but on linux machine it creates problem. Any body help to get interface statistics on linux machine also.

Did you check that your linux is answering snmp queries?

Try directly, from the linux shell:

snmpwalk -c <community> -v1 127.0.0.1 .1.3.6.1.2.1.2.2.1.1

According your screenshot, it tells you "No SNMP data returnet". Focus on it

[rmuhammadali]

Dear lcano,

I have already check and know that the query is not returing anything. my question is why it fetches the interface information of windows system and why not of linux (even it is installed on linux). second thing is how to fetch this information on linux (centos) machine.

Please help me or give some idea.

Regards
RMA

[lcano]

Are you running an snmp server in the linux to answer that queries?

[rmuhammadali]

i am using this (net-snmp-5.3.2.2-7.el5.i386.rpm) as a snmp responder.

[lcano]

Are you sure it is running?

Try with

netstat -an | grep 161

You should get something similar to this

udp 0 0 0.0.0.0:161 0.0.0.0:*

Check the snmp server configuration. It is not a cacti issue.
