Cortex Query Language comp sum aggregate returns the sum of an integer field in the result set.
Syntax
comp sum(<field>) [as <alias>] by <field_1>,<field_2> [addrawdata = true|false as <target field>]
Description
The sum aggregation is a comp function that returns the sum of an integer field, for all records that contain matching values for the fields identified in the by clause.
In addition, you can configure whether the raw data events are displayed by setting addrawdata to either true or false (default), which are used to configure the final comp results. When including raw data events in your query, the query runs for up to 50 fields that you define and displays up to 100 events.
Examples
Return the sum of the action_total_download field for all records that have matching values for their actor_process_image_path and actor_process_command_line values. The query returns a maximum of 100 xdr_data records and includes a raw_data column listing the raw data events used to display the final comp results.
dataset = xdr_data | fields actor_process_image_path as Process_Path, actor_process_command_line as Process_CMD, action_total_download as Download | filter Download > 0 | limit 100 | comp sum(Download) as total_download by Process_Path, Process_CMD addrawdata = true as raw_data
