Updates selected details of an existing Security Information and Event Management (SIEM) events stream. Running this operation using JSON Patch syntax creates a stream version that replaces the current one. Currently you can patch a stream using only the replace operation. When updating configuration objects such as destination or deliveryConfiguration, pass a complete object to avoid overwriting current details with default values for omitted fields such as tags, uploadFilePrefix, and uploadFileSuffix. Note that only active streams collect and send logs to their destinations. You need to set the activate parameter to true while patching active streams, and optionally for inactive streams if you want to activate them upon request. See Patching streams for details.
