Abstract

Explains how to run queries with Query Builder templates that do not require prior Cortex Query Language (XQL) knowledge.

You can use the Query Builder templates to create effective queries without using the Cortex Query Language (XQL).

How to create a query from a Query Builder template
  1. Select Incident ResponseInvestigationQuery Builder.

  2. In the Query Builder, select the template that you want to use.

    If you want to use the Free Text Search template, see Run a free text query.

  3. Enter values for any of the predefined fields and specify whether to include Empty values in the query.

  4. (Optional) Click Add Field and select the additional filtering fields or aliases to include in the query."

    Note

    • Field names and aliases are listed without their prefix, for example xdm.SOURCE.USER.USERNAME is listed as SOURCE.USER.USERNAME and XDM_ALIAS.ipv4 is listed as ipv4.

    • Fields that are already included in the query template are shown as grayed out.

    • In the Identity and Network templates, xdm.event.outcome shows as grayed out. In these templates, the ACTION STATUS and CONNECTION STATUS fields are linked to the xdm.event.outcome enum. Therefore, you can't duplicate this field in a query.

  5. Click TIME and select a time frame for the query.

  6. Click Run to start the query, or click Schedule to run the query at a specific time.

    You can also click Continue in XQL to open the XQL Query Builder showing the defined XQL fields. In XQL you have the flexibility to add additional stages and functions that are not available in the Query Builder templates.

  7. Review the Results.

    The search is limited to 1,000 results. In the Fields column, you can see all of the fields that were included in the query in the following order: (1) _time, (2) the filtering fields that you defined, and (3) the fields from the template specific fieldset.

    Note

    This order might change if you include a filtering field that is listed in the fieldset. In that case, the field is taken out of the fieldset and ordered at the top of the list with the other filtering fields.

    The query is also saved in the Query Center. In the Query Center, you can identify your query by filtering the Created By column and looking in the Query Description column. Queries created from a template are prefixed with the template name.

Example 19. Example
  • The following query searches for instances of IP 3.3.3.3 with a source host name equal to host1 or host2. IP is an alias field; therefore, the query searches all fields associated with the alias.

    IP ADDRESS = 3.3.3.3, SOURCE.HOST.OS = host1|host2
  • The following query searches for the event outcome success with an event duration value that is not equal to null:

    EVENT.OUTCOME = XDM_CONST.OUTCOME_SUCCESS, EVENT.DURATION != Empty values

What to do next
  • To edit or rerun the query, click Back to edit to review the template, or Continue in XQL to review the XQL.

  • Practice running queries with Query Builder template examples.
