Min

The MIN function returns the minimum value in a set of values. The following demonstrates the syntax of the MIN function.

Stream=firewall | groupby dstcn | select dstcn, min (evtlen)

Here,

• Stream is Firewall

• Groupby function allows to organize similar data into groups i.e. groupby destination country.

• Select function helps you to retrieve records from one or more tables, the records retrieved are known as a result set.

• The min ( ) function returns the lowest value (minimum) in a set of non-NULL values.

In this example, on execution it should retrieve all fields for each event where the stream is a firewall; it retrieves the minimum value in each group. The output is shown as below:
