[IM-Talk] Custom Probe Help needed

Sat, 25 Mar 2006 12:23:32 -0800 

Hi there,
I'm on the way to create a Custom Probe for some EMC Fibre Channel Switches. But I'm stuck with some basic problem lying in the nature of SNMP OID MIBS. The probe should deliver some In an Out statistics for each of the FibreChannel Switch Ports. 
With these values I would like to do some other stuff in the probe.
So I figured out the needed OIDs for the interface values.

Here is an example output for one of the needed tables:

You can see that if I do a snmpwalk on:


1.3.6.1.2.1.8888.1.3.1.1.3


I get all the values I need from two different switches
(BTW They are exactly the same but different configuration)
As you can also see the complete OID differs for the same value on the two switches.
So I can't use the full OID in the probe because they differ on each of the tested switches. 
I found something similar on this group:

<header>
         "type"                  =       "custom-snmp"
         "package"               =       "com.starkey"
         "probe_name"    =       "snmp.brocade"
         "human_name"    =       "SNMP - Brocade FC Switch"
         "version"               =       "1.1"
         "address_type"  =       "IP"
         "port_number"   =       "161"
</header>


But he works with fixed OIDs for each port.

So my easy question is...
Is there any possibility to read all the 24 Interfaces from a device with only the "short" 
OID an put the results in something like an array.
I think it should be possible because all of the standard intermapper switch probes 
can detect the ifnumber and the port statistics.


Any help welcome.
