SNMP: how to write trigger expression

[gorodgeroy]

Hi, guys!
I need to monitor printer's toner level. So I have this OID:
.1.3.6.1.4.1.2435.2.3.9.4.2.1.5.5.8.0
It returns string like 0x63 01 04 00 00 00 01 11 01 04 00 00 00 96 41 01 04 00 00 26 AC 31 01 04 00 00 00 01 6F 01 04 00 00 22 C4 81 01 04 00 00 00 5A 86 01 04 00 00 00 10 FF

Interesting part is 31 01 04 00 00 00 01 - last number shows level of toner (01 - full, 02 - low, 03 - empty, 04 - no device).

How can I write expression to find if substring differs from 31 01 04 00 00 00 01? I've found no clues, I know only that I should do something with {#SNMPVALUE} to compare it with 31 01 04 00 00 00 01

maybe the trigger should look somthing like this :

 
{Template SNMP Interfaces:ITEMKEY[{#SNMPVALUE}].str("31 01 04 00 00 00 03")}=1

menning that when ever it catch this string 31 01 04 00 00 00 03 it will fire alert, try this first with 01 to check
