Data Model Columns and Rows Transpose using Eval

TreeHut — Fri, 15 Feb 2019 00:34:28 GMT

Hello-
How do you transpose columns inside the Data Model using eval?

My goal is to filter a column called column1 inorder to extract data from a second column called column2. A third column would be created to only hold vales transferred from the second column. The name of this column would be column3.

column1
filter1
filter2
filter3

column2
data1
data2
data3

column3
null
data2
null

This code pulls the value randomly:

|eval if(like(column1,"filter2"),column2,NULL)

Field Name = column3

I need to extract the value from column2 using the same row referenced in column1.

Thanks!

Why use LIKE? Is not this a ”filter2%”?

Like this:

|makeresults | eval _raw="column1='filter1 filter2 filter3' column2='data1 data2 data3'"
| kv
| foreach column* [ rex field=<<FIELD>> mode=sed "s/'//g" | makemv <<FIELD>> ]
| eval filter="filter2"
| eval column3 = mvindex(column2, mvfind(column1, filter))
