Cacti interface data with HP Procurve Switches

[krismc]

Hi,

We've just picked up a couple of Procurve 2626 switches to use instead of our normal choice of Cisco but are having some trouble getting Cacti to read the interface information.

We have Cacti installed on a Debian server and the switch has been added as a Generic SNMP device in Cacti using SNMP v2.

Under 'SNMP Information' on the device page, Cacti displays:

Code: Select all

System: HP J4900B ProCurve Switch 2626, revision H.08.67, ROM H.08.02 (/sw/code/build/fish(f04))

...along with the hostname and uptime as usual. The "SNMP - Interface statistics" line in the "Associated Data Queries" shows

Code: Select all

Success [0 Items, 0 Rows]

and the verbose query output is:

Code: Select all

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

However, when I try to snmpwalk the same OID as cacti appears to be trying, I can enumerate the interfaces:

Code: Select all

support:/var/www/cacti/log# snmpwalk -c community xxx.xxx.xxx.xxx .1.3.6.1.2.1.2.2.1.1
interfaces.ifTable.ifEntry.ifIndex.1 = 1
interfaces.ifTable.ifEntry.ifIndex.2 = 2
interfaces.ifTable.ifEntry.ifIndex.3 = 3
...etc

Any ideas why Cacti can't see this but I can manually from the same machine that Cacti is installed on?

Many thanks,
Kris

Post a walk of the entire ifInterfaces tree please. It would appear that the "number of interfaces" value is not being returned:

Code: Select all

+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1' 
+ No SNMP data returned

Heya,

The following is the output of the entire snmpwalk for that oid.

Code: Select all

interfaces.ifTable.ifEntry.ifIndex.1 = 1
interfaces.ifTable.ifEntry.ifIndex.2 = 2
interfaces.ifTable.ifEntry.ifIndex.3 = 3
interfaces.ifTable.ifEntry.ifIndex.4 = 4
interfaces.ifTable.ifEntry.ifIndex.5 = 5
interfaces.ifTable.ifEntry.ifIndex.6 = 6
interfaces.ifTable.ifEntry.ifIndex.7 = 7
interfaces.ifTable.ifEntry.ifIndex.8 = 8
interfaces.ifTable.ifEntry.ifIndex.9 = 9
interfaces.ifTable.ifEntry.ifIndex.10 = 10
interfaces.ifTable.ifEntry.ifIndex.11 = 11
interfaces.ifTable.ifEntry.ifIndex.12 = 12
interfaces.ifTable.ifEntry.ifIndex.13 = 13
interfaces.ifTable.ifEntry.ifIndex.14 = 14
interfaces.ifTable.ifEntry.ifIndex.15 = 15
interfaces.ifTable.ifEntry.ifIndex.16 = 16
interfaces.ifTable.ifEntry.ifIndex.17 = 17
interfaces.ifTable.ifEntry.ifIndex.18 = 18
interfaces.ifTable.ifEntry.ifIndex.19 = 19
interfaces.ifTable.ifEntry.ifIndex.20 = 20
interfaces.ifTable.ifEntry.ifIndex.21 = 21
interfaces.ifTable.ifEntry.ifIndex.22 = 22
interfaces.ifTable.ifEntry.ifIndex.23 = 23
interfaces.ifTable.ifEntry.ifIndex.24 = 24
interfaces.ifTable.ifEntry.ifIndex.25 = 25
interfaces.ifTable.ifEntry.ifIndex.26 = 26
interfaces.ifTable.ifEntry.ifIndex.63 = 63
interfaces.ifTable.ifEntry.ifIndex.4158 = 4158

Kind regards,
Kris

Sorry,

You did not follow my instructions. Please walk the following:

.1.3.6.1.2.1.2.2

Sorry about that.

Many thanks,

Update:

We've just had someone else query these switches using their own Cacti install which seems to work as expected:

Code: Select all

+ Running data query [1]. 
+ Found type = '3' [snmp query]. 
+ Found data query XML file at '/var/www/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' 
+ Located input field 'ifIndex' [walk] 
+ Executing SNMP walk for data @ '.1.3.6.1.2.1.2.2.1.1' 
+ Found item [ifIndex='1'] index: 1 [from value] 
+ Found item [ifIndex='2'] index: 2 [from value]

Look in your Apache error log for some interesting entries. Also, please confirm wether or not you are using php_snmp.

Interesting indeed:

error.log contains the following after I try to requery the interfaces:

Code: Select all

Unknown output option passed to -O: Q.
Usage: snmpwalk [options...] <hostname> {<community>} [<objectID>]

UCD-snmp version: 4.2.3
  -h            this help message.
  -H            Display configuration file directives understood.
...and the rest of the usage guidelines

That's what I thought. What is happening is that since you don't have the PHP extension php_snmp loaded/built, Cacti is using the snmp binaries, which in your case are quite dated.

So, I guess I would definately update the net-snmp binaries and get away from the ucd-snmp (no longer under development) ones. If you update to net-snmp 5.2.x or even 5.1.x, you should be Ok.

Also, if you have a more recent version of PHP and the php_snmp library, it will speed the interface a bit.

Hello,

i have nearly the same problem. I have an ProCurve 1810G.

Cacti is showing the snmp data on the device list:

Code: Select all

HP Switch (192.168.178.250)
SNMP Information
System:HP ProCurve 1810G - 24 GE, P.2.2, eCos-2.0, CFE-2.1
Uptime: 1541700 (0 days, 4 hours, 16 minutes)
Hostname: PROCURVE J9450A
Location: Keller
Contact: User

Code: Select all

snmpwalk -v 2c -c public 192.168.178.250 .1.3.6.1.2.1.2.2

return nearly the same as krismc.

My NET-SNMP version is 5.4.3

and when i klick on "Verbose Query" i get only:

+ 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 get for num of indexes @ '.1.3.6.1.2.1.2.1.0' Index Count: 25
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1' Index Count: 0
+ No SNMP data returned

In my apache.log there are no matching errors
Can someone help me there?
