Request message for grouping by findings.
Expression that defines the filter to apply across findings.
The expression is a list of one or more restrictions combined
via logical operators AND and OR. Parentheses are
supported, and OR has higher precedence than AND.
Restrictions have the form <field> <operator> <value> and
may have a - character in front of them to indicate
negation. Examples include: - name -
source_properties.a_property - security_marks.marks.marka
The supported operators are: - = for all value types. -
>, <, >=, <= for integer values. - :,
meaning substring matching, for strings. The supported value
types are: - string literals in quotes. - integer literals
without quotes. - boolean literals true and false
without quotes. The following field and operator combinations
are supported: name | = parent | '=', ':' resource_name
| '=', ':' state | '=', ':' category | '=', ':'
external_uri | '=', ':' event_time | =, >, <,
>=, <= Usage: This should be milliseconds since epoch
or an RFC3339 string. Examples: "event_time =
"2019-06-10T16:07:18-07:00"" "event_time = 1560208038000"
security_marks | '=', ':' source_properties | '=', ':',
>, <, >=, <= For example,
source_properties.size = 100 is a valid filter string.
Time used as a reference point when filtering findings. The filter is limited to findings existing at the supplied time and their values are those at that specific time. Absence of this field will default to the API's version of NOW.
The value returned by the last GroupFindingsResponse;
indicates that this is a continuation of a prior
GroupFindings call, and that the system should return the
next page of data.
