Parsed and unparsed messages
Normally, the capture mechanism parses all parts of the message that are necessary to collect the information provided by the message. When the message or its part is encrypted, it is possible that the capture mechanism will not be able to decrypt (and parse) the full message contents, but will still be able to determine the type of the message and some PubSub header information. Such case is indicated by one of the unparsed capture types.
For more information to when the unparsed capture types are used, see Security and sniffing.
