Creating a multivalue field from a result?

dshpritz — Thu, 26 Dec 2013 16:39:07 GMT

Hey everyone,

So this feels like something I should be able to do with the standard search language, but I am failing at it.

I have a result, coming from a custom command, that contains field like this:

entries.0.category\_name, entries.1.category\_name,...,entries.n.category\_name

I would like to take all of these and either create a multi-value field with all of the values in them, or create just one string joining all of the values of entries.*.category_name together, with a comma.

I want something like:

| eval mvjoin(entries.*.category_name, ",")

But Splunk does not like that.

Any thoughts?

Thanks,

Dave

Try split command.

| | eval fieldName=split(fieldName, ",")

This will split value in the fieldName by comma and create a multivalued field out of it.

Hey somesoni2,

Thanks for the suggestion, but I want to join the values across an unknown number of fields, each named entries.n.category. That is, my example above is the field names, not the value in the fields.

Thanks,

Dave

So basically he has fields that are named "entries.InsertNumberHere.category_name" and would like to combine them into one multi-value field. Variably Named columns.

Try this:

...| eval categories = "" | foreach entries.*.category_name [eval categories='<<FIELD>>' + "," + categories]| makemv delim="," categories
