Passing credentials

WARNING

client_id and client_secret are keyword arguments that contain your CrowdStrike API credentials. Please note that all examples below do not hard code these values. (These values are ingested as strings.)

CrowdStrike does not recommend hard coding API credentials or customer identifiers within source code.

aggregate_external_assets

Returns external assets aggregates.

PEP8 method name

aggregate_assets

Endpoint

Method	Route
	/fem/aggregates/external-assets/v1

Content-Type

• Consumes: application/json
• Produces: application/json

Keyword Arguments

Name	Service	Uber	Type	Data type	Description
body			body	dictionary	Full body payload as a dictionary. Not required when using other keywords.
date_ranges			body	list of dictionaries	Applies to date_range aggregations. Example: [   {     "from": "2016-05-28T09:00:31Z",     "to": "2016-05-30T09:00:31Z"   },   {     "from": "2016-06-01T09:00:31Z",     "to": "2016-06-10T09:00:31Z"   } ]
exclude			body	string	Elements to exclude.
field			body	string	The field on which to compute the aggregation.
filter			body	string	FQL syntax formatted string to use to filter the results.
from			body	integer	Starting position.
include			body	string	Elements to include.
interval			body	string	Time interval for date histogram aggregations. Valid values include: year month week day hour minute
max_doc_count			body	integer	Only return buckets if values are less than or equal to the value here.
min_doc_count			body	integer	Only return buckets if values are greater than or equal to the value here.
missing			body	string	Missing is the value to be used when the aggregation field is missing from the object. In other words, the missing parameter defines how documents that are missing a value should be treated. By default they will be ignored, but it is also possible to treat them as if they had a value.
name			body	string	Name of the aggregate query, as chosen by the user. Used to identify the results returned to you.
q			body	string	Full text search across all metadata fields.
ranges			body	list of dictionaries	Applies to range aggregations. Ranges values will depend on field. For example, if max_severity is used, ranges might look like: [   {     "From": 0,     "To": 70   },   {     "From": 70,     "To": 100   } ]
size			body	integer	The max number of term buckets to be returned.
sub_aggregates			body	list of dictionaries	A nested aggregation, such as: [   {     "name": "max_first_behavior",     "type": "max",     "field": "first_behavior"   } ] There is a maximum of 3 nested aggregations per request.
sort			body	string	FQL syntax string to sort bucket results. _count - sort by document count _term - sort by the string value alphabetically Supports asc and desc using | format. Example: _count|desc
time_zone			body	string	Time zone for bucket results.
type			body	string	Type of aggregation. Valid values include: date_histogram - Aggregates counts on a specified time interval. Requires use of “interval” field. date_range - Aggregates counts on custom defined date range buckets. Can include multiple ranges. (Similar to time series, but the bucket sizes are variable). Date formats to follow ISO 8601. terms - Buckets alerts by the value of a specified field. For example, if field used is scenario, then alerts will be bucketed by the various alert scenario names. range - Buckets alerts by specified (numeric) ranges of a specified field. For example, if doing a range aggregation on the max_severity field, the alerts will be counted by the specified ranges of severity. cardinality - Returns the count of distinct values in a specified field. max - Returns the maximum value of a specified field. min - Returns the minimum value of a specified field. avg - Returns the average value of the specified field. sum - Returns the total sum of all values for the specified field. percentiles - Returns the following percentiles for the specified field: 1, 5, 25, 50, 75, 95, 99.
