snmpwalk

for the command below, does 1.3.6.1.4.1.2021.8.1.101 mean MIB, and the output refer to individual OID.

How can I check the detail of MIB & OID from a Linux server ? Tks

What kind of detail are you looking for?

You can for example do something like this to see details of an OID:

# snmpwalk -v 2c -c user host.domain.com system

Open in new window

This will give you all the details of that OID, in that list you have for example "sysDescr.0", which you can call directly with

# snmpwalk -v 2c -c user host.domain.com sysDescr

Open in new window

The result is passed by my supervisor to get some data from Apache such as invalid request, large object request...

My question is
- how to get 1.3.6.1.4.1.2021.8.1.101 ?
- how to know which OID is the data that I need ... ?

You can search OID's here, that might give you an idea on what to use in your snmpwalk,

Your specific OID refers to "extOutput", so you could try:

# snmpwalk -v 2c -c user host.domain.com extOutput

Open in new window

To clarify my understanding,

Using your provided link : http://www.oid-info.com/get/1.3.6.1.4.1.2021.8.1.101, it return
"extOutput". So, "1.3.6.1.4.1.2021.8.1.101" point to OID extOutput and the output return the subset (UCD-SNMP-MIB::extOutput.1, UCD-SNMP-MIB::extOutput.2 , UCD-SNMP-MIB::extOutput.3 ) under it, correct ?

Actually, I need to find out out each of these value represenent. Where can I get more detail. We are monitoring our Redhat Apache server...

Thanks again.
