How to extract fields in from this scenario? Fields within a field.

[adrianathome]

I have a field on my events that has the following:

john,12345,mark,2356,maria,4567
rachel,8883,john2,488475
nothing to report
NULL
peter,9993

I am trying to create two fields from this. Field1 is called employee, and field2 would be employeeid. I want my end product to look like this:

employee=john
employeeid=12345
employee=mark
employeeid=2356
...
employee=peter
employeeid=9993

The problem is that sometimes the events have 1 employe, other times more then one, and the field can also be empty.

I have been trying to achieve this with makemv or extract|kv with no successful results.

How would you guys/gals go about getting this done?

I would use a named transform with a regular expression, and use MV_ADD = true. You'll have to tie the transform to the sourcetype with a REPORT-... stanza in props.conf.

In that case, I might look at "mvexpand". The props / transforms that I described above creates a multi-valued field. mvexpand takes each of those values and splits it into its own event.

Awesome! That seem to have worked for the field=value part. Now, what do I need to do so that each field=value has its own event?
