Splunk Search Command Series: Rare

 

Remember we talked about the TOP command? Well turns out there is a command that works exactly the same way but you get results for the fewest occurrences in your data. 

It is called RARE. Where TOP provides you with the most common values in your data, rare shows you the values that occur the fewest. 

More About Rare

Something we can accomplish with the search below:  

index=main| stats count as count by user | sort count | head 10 

Again, an easy search, but we can make it easier 

Index=main| rare limit=10 user 

Wango Bango! Same results, less…search.

 

How to Use Rare

Let’s explore the syntax: 

|rare <options> field <by-clause> 

Options –  

  • Limit = limit the number of results 
  • Showperc =  show the activity percent field of the value 

Field = filed you want to find the top values of 

By-clause = a field you want to filter by 

And there you have it. Rare command is an easier search… but is important to utilize.
