trouble with SNMP - Interface Statistics

[RaduAlexandru]

I'm having trouble with SNMP - Interface Statistics.
The
Data Query Debug Information reads as following:

Code: Select all

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/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 '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'

But I have: "Success [0 Items, 0 Rows]".

Using

• Fedora Core 5 (SELinux disabled, Firewall disabled)
  Apache 2.2
  PHP 5.1
  MySQL 5.0
  Net-SNMP 5.3
  RRDTool 1.0.49

Any ideeas?
Thanks in advance.

Please run

Code: Select all

snmpwalk -c <your community string> -v 1 <your target> .1.3.6.1.2.1.2.2.1.1

and post the results (omitting your community string for sake of security). Does your DEVICE show a red error message in the upper left corner?

Code: Select all

snmpwalk -c public -v 1 192.168.22.33 .1.3.6.1.2.1.2.2.1.1

dosen't output anything

snmpwalk -c public -v 1 192.168.22.33 .1.3.6.1.2.1.2.2.1.1

If that fails, cacti would not make more out of this. Please try to

Code: Select all

snmpwalk -c public -v 1 192.168.22.33 system

If that fails either, then snmpd has not been set up properly for that device. If only the above fails (.1.3.6.1.2.1.2.2.1.1), that OID is not supported by your target

I modified some of the strings in /etc/snmpd/snmp.conf.

[gandalf]

When modifying snmp(d).conf on the target host, don't forget to refresh/restart the daemon to take effect. Then, please

Code: Select all

snmpwalk -c public -v 1 192.168.22.33 interfaces

to check, whether interfaces are shown. Modifying snmp(d).conf on cacti's host won't change anything
Reinhard

[RaduAlexandru]

I had reseted the computer several times when I tried the commands. Here is the output:

Code: Select all

[root@localhost ~]# snmpwalk -c public -v 1 192.168.22.31 interfaces
[root@localhost ~]#
---------------
[root@localhost ~]# snmpwalk -c public -v 1 localhost interfaces
[root@localhost ~]#

I changed the IP of the server. In case it helps I can post the snmpd.conf file too.

[fmangeant]

Hi

can you try with this in /etc/snmp/snmpd.conf :

Code: Select all

rocommunity public
disk /

[RaduAlexandru]

fmangeant: I'm new to snmp... could you give me the exact lines?
Should I change

Code: Select all

####
# First, map the community name "public" into a "security name"

#       sec.name  source          community
com2sec notConfigUser  default       public

to

Code: Select all

####
# First, map the community name "public" into a "security name"

#       sec.name  source          community
com2sec notConfigUser  default       rocommunity public 

?
_________________
Later Edit:
If I use

Code: Select all

####
# First, map the community name "public" into a "security name"

#       sec.name  source          community
com2sec notConfigUser  default       rocommunity public 

and I run

Code: Select all

[root@localhost ~]# snmpwalk -v 1 localhost -c "rocommunity public"
Timeout: No Response from localhost
[root@localhost ~]#

If I don't use double quotes it shows me the help screen.

[fmangeant]

Rename /etc/snmp/snmpd.conf to something else, and put these 2 lines in /etc/snmp/snmpd.conf :

Code: Select all

rocommunity public
disk /

You need to restart the SNMP agent.

[RaduAlexandru]

fmangeant: Ok. I added the two lines at the end of snmpd.conf and when I run the commands here is what I get:

Code: Select all

[root@localhost ~]# snmpwalk -c public -v 1 192.168.22.31 interfaces
[root@localhost ~]# snmpwalk -c public -v 1 localhost interfaces
[root@localhost ~]#

If I erase the content of snmpd.conf and I add the two lines you gave me I get:

Code: Select all

What does that meen? Should I leave the snmpd.conf empty, with only these lines?

[fmangeant]

What does that meen? Should I leave the snmpd.conf empty, with only these lines?

Yes, you can leave the snmpd.conf with these 2 lines.
If you want to graph several filesystems, replace

Code: Select all

disk /

by

Code: Select all

includeAllDisks

You can now graph network interfaces by re-loading the "SNMP - Interfaces traffic" data query.

[RaduAlexandru]

Will it still work if I add some lines like

Code: Select all

System: 
Hostname: 
Location: 
Contact: 

and maby some other that give description?

[fmangeant]

Yes, something like this will work :

Code: Select all

rocommunity public
includeAllDisks
syslocation My site
sysname router_1
syscontact me@howhere.com

[RaduAlexandru]

What other stuff must I add in order to get SNMP - Get Processor Information to work? SNMP - Interface Statistics and SNMP - Get Mounted Partitions work just fine.

And regarding snmpd.conf... after the first two lines there must be a white space. Like this:

Code: Select all

rocommunity public
includeAllDisks

syslocation Romania, Bucharest, str. Vlad Dracu, nr. 3, bl. B12
