Only one field is ever populated at any one time so it is a bit redundant to have two fields that hold very similar information. These should just be combined into a single field.

If you always want the two fields to be combined, and they won't both be populated at once, you could make a field alias to rename field1 as field2 or vice versa. Attachments: Up to 2 attachments including images can be used with a maximum of Answers Answers and Comments.

Edited by landen This assumes that field1 and field2 are numeric.

If they are not, you can use the following instead:. Note that a semicolon ; is used as a delimiter, so a semicolon cannot appear in either field1 or field2. Apparently they did, but I could not find where they were. I also had to manipulate this solution some to get what I wanted. I had to fields that had IPs in them so I did this. I found this to be correct. Note that the tostring is not necessary if you use the proper concatenation character.

Your solution would end up with 3 events, not 6. And your 3 events would have a multi-valued field named output. Nothing wrong with that, but it might be hard to work with, depending on what you wanted to do next.

BTW, if you wanted, you could also create field aliases that would make your renames "permanent" so that you don't have to do the renames every time. My specific use case worked as I was dealing with 6 different log events so the source looks like this:. I downvoted this post because the solution does not work.

This runs the search twice Otherwise, this will search over all time - it is not affected by the time selector. Well give more details.

You didn't state that this was going to be used across millions events. Also you need to give more details on the search you're using to generate these fields.

Do field1 and field2 belong to the same search result? Do both fields always occur in all events you want to apply this to? The subsearch naturally carries the time of the outer search unless otherwise specified, as I understand it.

Agreed landen99but that was not true in :. Hiii, I'm having a similar query but not getting output Actually, I have created fields and I want to merge two fields into a single field Can extract the new field directly by merging old two fields???

The specified field becomes a multivalue field that contains all of the single values from the combined events. There are situations where the mvjoin eval function is a better option than the mvcombine command. See Usage. To see the output of the delim argument, you must use the nomv command immediately after the mvcombine command. The mvcombine command is a transforming command. See Command types. You can use evaluation functions and statistical functions on multivalue fields or to return multivalue fields.

The mvcombine command accepts a set of input results and finds groups of results where all field values are identical, except the specified field. All of these results are merged into a single result, where the specified field is now a multivalue field. Because raw events have many fields that vary, this command is most typically useful after paring down the set of available fields with the fields command.

The command is also useful for manipulating the results of certain reporting commands. The mvcombine command creates a multivalue version of the field you specify, as well as a single value version of the field.

The multivalue version is displayed be default. The single value version of the field is a flat string that is separated by a space or by the delimiter that you specify with the delim argument. By default the multvalue version of the field is displayed in the results. To display the single value version with the delimiters add the nomv command to the end of your search. For example Some forms modes of investigating the search results prefer this single value representation, such as exporting to CSV in the UI, or running a command line search with splunk search " Some commands that are not multivalue aware might use this single value as well.

Most ways of accessing the search results prefer the multivalue representation, such as viewing the results in the UI, or exporting to JSON, requesting JSON from the command line search with splunk search " For these forms of, the selected delim has no effect. If the field is a multivalue field and you want a single valued field with a different delimiter, use the mvjoin evaluation function.

For example, a multivalue field contains the values "1","2","3","4","5". Use the mvjoin function and not the mvcombine command. See Multivalue Eval Functions. The results show that the max and min fields have duplicate entries for the hosts that start with www.The fieldsummary command calculates summary statistics for all fields or a subset of the fields in your events.

The summary information is displayed as a results table. The fieldsummary command displays the summary information in a results table. The following information appears in the results table:. In this example, the results in the maxminand stdev fields are formatted to display up to 4 decimal points. The search returns only the top 10 values for each field from the last 15 minutes.
