Graph Generated but no inbound & outbound info

[alexito]

Hi Guys,

I just joined the forum and I am having abit of a problem. My graphs are displaying but they appear empty. There are no inbound and outbound traffic generated for any of the devices I am polling from. I can attach devices and cacti can talk to them all right but I get empty graphs with no inbound and outbound traffic information on them.

This is my OS environment

Redhat Enterprise Server AS
Apache 2.0.52
PHP 4.3.3
rrdtool 1.0.49
net-snmp 5.1.2
mysql 4.0.21
cacti 0.8.6g with all patches applied

Please assist, as I am new to cacti and will appreciate any help.

Here are the output from my cacti logs

"Results from SNMP not valid" tells us, that there is an snmp problem. Please switch to DEBUG mode (see: Settings) on run at least one polling cycle. Look at your cacti.log a you'll see the failing OID. Check that OID using snmpwalk from command line.

Thanks for replying. I am new to cacti so you will have to be a little patient with me.

[Please switch to DEBUG mode (see: Settings) on run at least one polling cycle]

I hope this is what you are talking about, please tell me if I am doing the wrong thing.

Is this the way to run the polling cycle?

[Check that OID using snmpwalk from command line. ]

How do I do that?


Thanks

[rony]

In your settings, what SNMP Utility Version do you have selected?

[alexito]

net-snmp-5.1.2

Please, how do I check the OID using snmpwalk from command line?

[nugai]

Please, how do I check the OID using snmpwalk from command line?

Try this for a list of interfaces:

Code: Select all

snmpwalk -v 1 -c  public 62.56.205.3 .1.3.6.1.2.1.2.2.1.1

The notation is:

Code: Select all

"snmpwalk -v 1 -c  <community>  <IPaddress>  <OID>", where:

"-v 1" defines the SNMP version (in this case SNMP version 1).
"-c  <community>" defines the SNMP community name ("-c public" is usually the default).
"<IPaddress>"  is the IP address your polling (e.g. "62.56.205.3")
"<OID>" is the OID (e.g. ".1.3.6.1.2.1.2.2.1.1" .

BTW: Your debug shows:

Code: Select all

Timeout: No Response from 62.56.205.3:161. 

In my limited experience (I too am new to cacti and SNMP), this indicates a SNMP version problem (e.g. sending SNMP v2 instead of SNMP v1).

Good luck.

[alexito]

ok.

I did just that

snmpwalk -v 1 -c public 62.56.205.3 .1.3.6.1.2.1.2.2.1.1

and I got

Timeout: No Response from 62.56.205.3

I installed net-snmp-5.1.2 as stated on the .pdf documentation on cactis' website.

How do I fix this problem. Thanks for your help for far, at least we have identified the problem.

[alexito]

ok.

I did just that

snmpwalk -v 1 -c public 62.56.205.3 .1.3.6.1.2.1.2.2.1.1

and I got

I installed net-snmp-5.1.2 as stated on the .pdf documentation on cactis' website.

[nugai]

OK. Try the next higher SNMP version:

Code: Select all

snmpwalk -v 2c -c  public 62.56.205.3 .1.3.6.1.2.1.2.2.1.1

[nugai]

In your firewall(s), do you have IP ports 161 and 162 open on both the host that is polling and the device being polled?

[nugai]

Can you log into the device being polled and verify whether the SNMP community is "public" or something else?

[alexito]

There are no firewall rules and the community string for the device is correct. What I noticed is that when connecting to the device, if I use version 1 on the host, it generates a SNMP error but when I use version 2, it polls information from the device all right. This shows that version 2 of SNMP is running on the device.

We use intermapper to monitor all traffic on our network and it works well. We want to give customers the ability to check their bandwidth usage with cacti.

Can you advice what next I should do, should I re-install net-snmp.

[nugai]

What I noticed is that when connecting to the device, if I use version 1 on the host, it generates a SNMP error but when I use version 2, it polls information from the device all right. This shows that version 2 of SNMP is running on the device.

Does that mean you are getting a response using snmpwalk with version 2?

[alexito]

The host uses SNMP version 2. I don't know what version I am using on my server. How can I find that out?

[nugai]

The terms "host", "device" and "server" seem to be used in different contexts. Which is which and what are they?
