Parser for AQL queries and GUI expressions from CSV files.

class axonius_api_client.api.wizards.wizard_csv.WizardCsv(apiobj, log_level='debug')[source]¶

Bases: Wizard

Parser for AQL queries and GUI expressions from CSV files.

Notes

This wizard can create as many saved queries as you like. The first row of the CSV must always have a type value of “saved_query”. All rows under that row will be added to that saved query until another row with a type value of “saved_query” is found. Repeat this pattern as you see fit.

The description, tags, and fields columns are only used for types of “saved_query”

Examples

Create a client using axonius_api_client.connect.Connect and assume apiobj is either client.devices or client.users

>>> apiobj = client.devices  # or client.users

Define a CSV string to parse

>>> content = '''
... type,value,description,tags,fields
... saved_query,name of sq,description  of sq,"tag1,tag2, tag4","os.type,default, aws:aws_device_type"
... simple,hostname contains test,,,
... simple,os.type equals windows,,,
... saved_query,name of second sq,description  of sq,"tag1,tag2, tag4",
... simple,hostname contains test,,,
... complex,installed_software // name contains chrome // version earlier_than 82,,,
... simple,os.type equals windows,,,
... '''

Parse the CSV string into a query and GUI expressions

>>> parsed = apiobj.wizard_csv.parse(content=content)
>>> for sq in parsed:
...   sq['name']
...   sq['query'][:80]
...   len(sq['expressions'])
...
'name of sq'
'(specific_data.data.hostname == regex("test", "i")) and (specific_data.data.os.t'
2
'name of second sq'
'(specific_data.data.hostname == regex("test", "i")) and (specific_data.data.inst'
3

Or parse a CSV file directly

>>> parsed = apiobj.wizard_csv.parse(path="~/test.csv")

Use the result to create saved queries that the GUI understands

>>> sqs = [apiobj.saved_query.add(**sq) for sq in parsed]
>>> for sq in sqs:
...    sq['name']
...    sq['uuid']
...    sq['view']['query']['filter'][:80]
...
'name of sq'
'5f79e90be4557d5cbab26344'
'(specific_data.data.hostname == regex("test", "i")) and (specific_data.data.os.t'
'name of second sq'
'5f79e90be4557d5cbab26359'
'(specific_data.data.hostname == regex("test", "i")) and (specific_data.data.inst'
