Splunk Search

Multi-line, Multi-value Key Extraction Issue

Hello Splunkers 🙂

I'm trying to perform some field extractions in a log similar to the one below:

29/02/2012 16:00 - Printer Usage Report
Printer 1: Canon (123)
Printer 2: Brother (456)
Printer 3: Xerox (789)
Printer 4: Epson (012)
Printer 5: HP (345)
**** END REPORT ****

From this I'm looking for Splunk to extract the 5 values for the field "printer" as well as the values in the parentheses into a "toner_level" field. All from a single event.

What should be my approach here? I've been looking at the various doco (props, transforms, fields) but can't really make any headway...

Any help would be greatly appreciated!

You can do it two ways.

1.From Search Bar:

... | rex max_match=10 "(?i)printer\s\d+:\s(?<printer>\w+)\s+\((?<tonner_level>\d+)\)"

2.You can persist extractions using props.conf and transforms.conf combination:

props.conf

[my_sourcetype]
REPORT-my_report = report_mv

transforms.conf

[report_mv]
REGEX = (?i)printer\s+\d+:\s(\w+)\s+\((\d+)\)
FORMAT = printer::$1 toner_level::$2
MV_ADD = true

Notice the MV_ADD attribute in transforms.

Hope this helps.
