extract

The extract compute allows to extract a part of a column and replace this column by this part. The subSeparators value is used to split the original column into an array and the subColumn value is used to chose a single column from this array.

connector:
  # ...
pre: # <object>
  <sourceKey>: # <source-object>

monitors:
  <monitorType>: # <object>
    <job>: # <object>
      sources: # <object>
        <sourceKey>: # <source-object>
          computes: # <compute-object-array>
          - type: extract
            column: # <number>
            subColumn: # <number>
            subSeparators: # <string>

Example

In this example, let's suppose the column 1 is the speed of a CPU in GHz where the value is separated from the unit by a space character:

| 2.5 GHz | | 1.35 GHz | | 3.4755 GHz |

This extract will split this column on every space character and keep only the first value.

          - type: extract
            column: 1
            subColumn: 1
            subSeparator: ' '

Then the value of the column 3 after the extract will be:

| 2.5 | | 1.35 | | 3.4755 |
