Distinct

Distinct

The distinct function is used to avoid duplicate values present in any specific columns/table. The following illustrates the syntax of the distinct() function:

stream=firewall |groupby dstip |select distinct(dstip)Copy

Here,

• Stream is Firewall
• Groupby function allows to organize similar data into groups i.e. Destination IP Address.
• Select function helps you to retrieve records from one or more tables, the records retrieved are known as a result set.
• The distinct (field) clause is used to remove duplicates from the result set.

In this example, on execution it should retrieve all fields for each event where the stream is a firewall, the DISTINCT clause kept only the distinct destination IP Address and removed all the duplicate values. The output is shown as below:
