Splunk Search Command Series: mvzip

 

 

Need some help zipping up your data in Splunk? This week’s Search Command should do the trick. The Splunk Search Command, mvzip, takes multivalue fields, X and Y, and combines them by stitching together.

Today, we are going to discuss one of the many functions of the eval command called mvzip. This function can also be used with the where command and the fieldformat command, however, I will only be showing some examples of this function using the eval command.

If you have been following our eval series, I am sure by now you know that the eval command is very versatile. Now let’s dive into another tool in the eval command’s tool belt! Let’s also use another command that we just learned called makemv to help facilitate this lesson. First, let’s make some data that has multiple field values.

I’ve created three new fields called name, grade, and subject. Within each of these fields, we have multiple values. Let’s say we want to create a new field with these values “zipped” together. For example, I want to know what subjects Mike is taking all in one field. This is where mvzip comes in.

Here, I have created a new field called “zipped” with the values from the name and subject fields. Now we can see that Mike is taking Math, Science, History, and English. Next, I want to know what grades Mike has in those subjects (a.k.a. report card time!).

Using mvzip, we can see what grades Mike has in each subject. As you can see from the SPL above, I have mvzip the third field “grade” to the other two by adding another mvzip function. Splunk only allows you to zip three fields together, so this is our limit here! Also, if you noticed I added a different delimiter to our final results. I have a pipe separating my values instead of a comma in my first example. You can use whatever delimiter you want when using the mvzip function by putting quotes around the delimiter.

That is it for now, I hope you enjoyed this lesson and I hope you try this out in your own environment, happy Splunking! P.S. I think Mike could use some tutoring in History and English😂😂
