Monitoring a ProCurve 2824 via SNMP

Oliver_36 — Tue, 18 Jan 2005 05:57:45 GMT

Hi,

I would like to monitor some ProCurve 2824 via SNMP from a linux box. Is there an documentation of the snmp-variables? For example I would like to monitor the fan status and speed and so on.

thx help!

Regards,
Oliver

You can start by downloading the MIBs
http://www.hp.com/rnd/software/MIBs.htm

You can also walk the MIBs with the walkMIB command as explained in the documentation that comes with the switches. I prefer to walk it with MG-SOFT.

I have downloaded the MIBs, at the moment i use the net-snmp tools to get the information from the switches. Where can I found the software walkMIB or MG-SOFT? I'm not very familiar with the HP Software.

Hi !

In net-snmp you can use this command :

snmpwalk -On -c public -v 1 IP-ADDRESS

Then you can browse the switch to see what
snmp information you can get out of the switch.

WalkMIB is a switch OS CLI command
MG-SOFT is available from http://www.mg-soft.com/index.html

Use Advent MIB Browser. its a java program with GUI user friendly.

or

As you have Net-SNMP installed you can use the following command on terminal to get information

snmpwalk -v 2c -c

you can walk without giving any OID or use this OID < .1.3.6.1.4.1.11>.

I understand how to use the net-snmp package, my question is: which OID is for the fan status, fan speed, the thermal sensors and so on - is there an document that describe these things?

Oliver

Is there a document publicly available? I think not. That is where a good SNMP tool like MG-SOFT can be your friend. You could of course just scour through the uncompiled MIBs since almost every OID has some sort of description, but if you use MG-SOFT to walk the MIB, you can see both the OID and the description.

BTW, I just did a quick walk through my 2848 and did not see any values in the OIDs you are looking for so I suspect that HP may not report those values. Maybe if you are lucky, someone will prove me wrong.

HI!
first lets make clear you must Load the correct MIB file to get the OIDs for fan, sensors and temp etc.

try to load the correct MIBs in ur MIB BROWSER and then try to walk ,you might get what you are actually looking for.

http://www.oidview.com/mibs/detail.html
select enterprise HP then you get a lots of MIB files on the link above for different information.depending on your requirement download the Mibs and load it on MIB BROWSER

I am attaching a HPentmib try using it first.

Hi Rajinikanth,

thx for your informations.

I load the HP MIBs in my MIB Browser but I can't walk through the OIDs. For example:

There is an OID: .1.3.6.1.4.11.2.3.7.8.3.3 (icfTemperatureSensor)

If I do:
snmpwalk -v 2c -c public 10.0.255.200 .1.3.6.1.4.11.2.3.7.8.3.3
I get: SNMPv2-SMI::private.11.2.3.7.8.3.3 = No Such Object available on this agent at this OID

I think this OID should available on the switch if there is an entry in the MIB Browser?

thx for help!

did you tried to walk via a mib browser
software

if u use the snmpwalk CLI u must have the mibs in ur NET-SNMP folder where it looks for MIBs source file.

I don't know where you are getting that OID information from, but even if you tried walking that MIB from a TelNet session on the switch itself, it would fail.

HP ProCurve Switch 2848# walkmib 1.3.6.1.4.11
No such variable: 1.3.6.1.4.11.
HP ProCurve Switch 2848#

When you walk the MIB in that way, since it is at the switch, there is no need for any MIBs to be loaded or compiled.

I have to assume that you typod on that OID. Even compensating for it and entering the correct OID and working backwards, returns no values.

HP ProCurve Switch 2848# walkmib
Incomplete input: walkmib
HP ProCurve Switch 2848# walkmib 1.3.6.1.4.1.11.2.3.7.8.3.2
No such variable: 1.3.6.1.4.1.11.2.3.7.8.3.2.
HP ProCurve Switch 2848# walkmib 1.3.6.1.4.1.11.2.3.7.8.3
No such variable: 1.3.6.1.4.1.11.2.3.7.8.3.
HP ProCurve Switch 2848# walkmib 1.3.6.1.4.1.11.2.3.7.8
No such variable: 1.3.6.1.4.1.11.2.3.7.8.
HP ProCurve Switch 2848# walkmib 1.3.6.1.4.1.11.2.3.7
No such variable: 1.3.6.1.4.1.11.2.3.7.
HP ProCurve Switch 2848# walkmib 1.3.6.1.4.1.11.2.3
No such variable: 1.3.6.1.4.1.11.2.3.
HP ProCurve Switch 2848#

What I said already "BTW, I just did a quick walk through my 2848 and did not see any values in the OIDs you are looking for so I suspect that HP may not report those values. Maybe if you are lucky, someone will prove me wrong." still stands.

ok, I unterstand you but there a some mibs from HP with this OIDs (fan, temperature and like this) this is strange......

I use the MIB browser from iReasoning (www.ireasoning.com) and mbrowse on my linux box.

I don't like to be the bearer of bad news, but I believe those OIDs are just not supported on the 28xx. If they were, walking the MIB at the switch would have revealed values. Like I said, no MIB files are involved when walking at the switch's console.

The MIBs from HP are general purpose for several models and just because they define certain OIDs, does not mean that every model of HP switch will support every OID.

Sorry
