Extracting multiple field values from a comma seperated list

Josh

Hello All,

What is the best way to extract into a single field mutiple values from a comma-seperated list:

Example: xxxx Books:1,2,3,65,2,5 xxxxxx

From this I have created a field called Books which contains the string 1,2,3,65,2,5 however what I would like to do is create a field called Books which takes each value as a single entry.

So from the above example I would have 6 entries in the field Book for this particular log entry.

If you have extracted the field Books with a single value of 1,2,3,65,2,5 and want it to report as a multi-valued attribute, try this at search time:

Books = * | makemv delim="," Books

Just in case, the other option is to use transforms.conf and fields.conf

This can be easily done through regex on your props.conf & transforms.conf:

  • props.conf
[sourcetype_for_the_csv]
REPORT-multifield = multifield
  • transforms.conf
[multifield]
REGEX = Books:(\d+,\d+,\d+,\d+,\d+,\d+)
FORMAT = book::$1
