No. I don't know how they work well enough yet. In my understanding thus far traps give you the ability To both poll and modify SNMP OID values. The reason I'm Liking SNMP is because I'm _not_ risking a value change... This means that an idiot can check the netapp status with SNMP with no danger of harming the system. That's why I like SNMP. Purhaps this afternoon I'll study traps a bit more......

Can you think of any reasons I might want to use traps?

Have you ever tried to get an SNMP out of one of those traps without killing it ??

Is there any reason not to use snmp traps ?

Hello Toasters.

I'm trying to write a simple dainty application to check for drive failures in our Filers. I'm going to implement this app in a PERL script which will use UCD SNMP to pull variables from the Filers. The problem is that when I walk the SNMP tree on a Filer I only get

network

statistics. I'm getting info in the following manner:

# export MIBFILE="/usr/local/share/snmp/mibs/netapp_1_5.mib" # snmpwalk -v 1 bigfiler public

I get about 2027 lines of output with IP, TCP, UDB, SNMP stats, plus address translation tables. But what I really want to see is the the RAID tables. Any idea what I need to do? I've found no help elsewhere on the net, including NetApp's NOW site. I DID find one page on NOW that listed several SNMP Groups found in the MIB, but I don't know how to access them.

Any help is appreciated.
