Given a Multiline Event, Can I Create a KV Fields from each row?

[mzorzi]

I have some log like following:

13:47:04 -2 receive request [type=0|desc=TimeStamp] <---event one
| [8 ] [BCA3.5]
| [9 ] [56]
| [35 ] [0]
| [49 ] [UBDHKH]
| [56 ] [LEHUBAUS]
| [34 ] [1709]
| [52 ] [20100512-05:47:05]
| [10 ] [182]
13:47:03 -2 sending request [type=0|desc=Request Change] <---event two
| [35 ] [0]
| [57 ] [INADM]
| [56 ] [UBDHKH]
| [49 ] [LEHUBAUS]
| [34 ] [2179]
| [52 ] [20100512-05:47:03]
| [8 ] [BCA3.5]
| [9 ] [0065]
| [10 ] [041]
........

The number of the left hand side is some meaningful code internally, I want to use left hand side as fields and it is the value for right hand side.

I've tried to extract the fields using REPORT- in props.conf, but the REPEAT_MATCH=true seems not working on Search-extracted fields and also a FORMAT value like : FORMAT=fields_$1::$2 is not correctly recognized.

Correct, unfortunately search-time extractions won't let you do anything more exotic than $1::$2 to map keys and values. However, you can actually use numbers as field names (it probably gets ambiguous syntactically for some commands, but you can deal with those ad hoc). Just add CLEAN_KEYS = false to your transforms.conf stanza, and use $1::$2 to create KV pairs, and you'll wind up with fields named 35, 10, etc.
