### This is observed the trap opEvents is receiving, and
### is the best candidate to become the element property:
STARENT-MIB::starSlotNum=6
### Refering to the vendors mib file starSlotNum is found:
starSlotNum OBJECT-TYPE
SYNTAX Integer32(1..48)
MAX-ACCESS accessible-for-notify
STATUS current
DESCRIPTION
"The slot number"
::= { starSlotEntry 1 } |
Based on this we can write the regular expression to set the element.

2 => {
DESCRIPTION => 'Set element for card number.',
IF => qr/(STARENT-MIB::starSlotNum=\d+)/,
THEN => ["capture(element)"],
}, |
Notice the regular expression will catch an number of digits following the '=' character. This rule 'captures' the element. In this way we can dynamically assign event properties based on a regular expression.
