Decode XML Wineventlog
editDecode XML Wineventlog
editThis functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
The decode_xml_wineventlog
processor decodes Windows Event Log data in XML format that is stored under the field
key. It outputs the result into the target_field
.
The output fields will be the same as the winlogbeat winlog fields.
The supported configuration options are:
-
field
-
(Required) Source field containing the XML. Defaults to
message
. -
target_field
-
(Required) The field under which the decoded XML will be
written. To merge the decoded XML fields into the root of the event specify
target_field
with an empty string (target_field: ""
). The default value iswinlog
. -
overwrite_keys
-
(Optional) A boolean that specifies whether keys that already
exist in the event are overwritten by keys from the decoded XML object. The
default value is
true
. -
map_ecs_fields
-
(Optional) A boolean that specifies whether to map additional ECS
fields when possible. Note that ECS field keys are placed outside of
target_field
. The default value istrue
. -
ignore_missing
-
(Optional) If
true
the processor will not return an error when a specified field does not exist. Defaults tofalse
. -
ignore_failure
-
(Optional) Ignore all errors produced by the processor.
Defaults to
false
.
