3.1.4.1.30.1 Subscription Options
The following options are available for OptionSet block for both collector-initiated and publisher-initiated event subscriptions.
|
Option |
Description |
|---|---|
|
Compression |
This option determines the compression algorithm used. Web Services Management Protocol Extensions for Windows Vista supports the SLDC algorithm, so the only valid value of "SLDC" is allowed. The HTTP packet containing compressed data MUST have the Content-Encoding set to SLDC. It is an ECMA standard (ECMA-321), as specified in [ECMA-321]. |
|
CDATA |
This option determines if the data (event xml) is to be parsed or passed unprocessed. It has the xsi:nil attribute associated with it, whose value, if set to true, indicates that the data is not to be processed by the Web Services Management Protocol Extensions for Windows Vista service. In that case, the data is considered a BLOB and passed as-is to the event subscriber for interpretation. If the option is set to false or is not specified the Web Services Management Protocol Extensions for Windows Vista service MUST parse the event content and validate that it is well-formed XML, and MUST deliver the event as specified in [DMTF-DSP0226] section 10.2. |
|
ContentFormat |
This option determines how the event data will be received by the event subscriber. If the value of this option is "RenderedText", both the event data and rendering information are passed, whereas event data is contained within the element <EventData> and rendering info is contained with the element <RenderingInfo>, so that the event can be displayed by the event subscriber according to a predefined format. The default value for this option is "Raw", which means that only event data will be passed without any rendering information. |
|
IgnoreChannelError |
This option determines if various filtering options resulting in errors in different channels are to result in termination of the processing. It has the xsi:nil attribute associated with it, whose value is set to "true", meaning that the filtering errors in different channels MUST be ignored by the subscription service and processing SHOULD continue. |
|
ReadExistingEvents |
This option has the same effect as the predefined, reserved bookmark http://schemas.dmtf.org/wbem/wsman/1/wsman/bookmark/earliest, as specified in [DMTF-DSP0226] section 10.2.6. If a subscription is received with this option set to "true", the event source SHOULD replay all possible events that match the filter and any events that subsequently occur for that event source.<84><85> |
