Lowest

Lowest

Returns lowest non-null value from the list of int values. @param default (optional), Type int. If provided none of the input values are non-null, returns default, Input must be a number or list of numbers.

This function is helpful when a user wants to get the lowest value from a dataset (or set of column values).

Example 1:

Step 1: Create an empty lowest_example_1 using AIOps studio as shown in the below screenshot.

Empty pipeline

Step 2: Add the following pipeline code/commands into the above-created pipeline as shown in the below screenshot:

You can copy the below code into your pipeline and execute that in your environment. ##### This pipeline creates a list of rows with various numbers (int values) for various ##### ids using AIOps studio. ##### RDA function lowest is used to demo this example. In this pipeline, each row added ##### has three columns with various numerical values. Pipeline uses RDA dm function ##### lowest to pick the lowest value from set of values and prints that value ##### for each row/id. @dm:empty --> @dm:addrow id = 'a1' & x = 10 & y = 3 & z = 9 --> @dm:addrow id = 'a2' & x = 1 & y = 13 & z = 4 --> @dm:addrow id = 'a3' & x = 7 & y = 3 & z = 3 --> @dm:addrow id = 'a4' & x = 4 & y = -1 & z = 9 --> @dm:map to = "MIN_VALUE" & from = "x,y,z" & func = 'lowest'

Pipeline code added to empty pipeline created

Step 3: Click verify button to make sure syntax and pipeline code is correct (as shown below)

Pipeilne code is verified using 'Verify' button as shown above.

Step 4: Click execute button and execute the pipeline. RDA will execute the pipeline without any errors (as shown below)

Successful execution of pipeline without any errors

Step 5: RDA uses the dm function 'lowest' to select the 'lowest' numerical number (or value) from the dataset and map that to variable "MIN_VALUE" and prints the output for each dataset (or row) as shown in the following screenshot.

Lowest value is printed for each dataset in the MIN_VALUE

Similarly, dm: function 'lowest' can be used to select the lowest value(s) from the selected dataset.
