Understanding Host Data Structures
This chapter describes the format of the Full Host Profile data block that conveys a set of data describing a single host. The eStreamer server generates and sends these blocks on request for host data. For information about the client request procedure, the message structure, and the delivery method, see Host Data and Multiple Host Data Message Format.
eStreamer uses the series 1 data block structure to package these Full Host profile blocks. For the general structure of series 1 blocks, see Series 1 Data Block Header. The Full Host Profile data block contains a number of encapsulated blocks which are individually described in the subsections where they are defined in Understanding Discovery & Connection Data Structures.
See the following sections for more information about current and legacy Full Host Profile data blocks:
- Full Host Profile Data Block 5.3+ describes the current Full Host Profile data block structure.
- Full Host Profile Data Block 5.0 - 5.0.2 describes the legacy Full Host Profile data block structure for versions 5.0 - 5.0.2.
Full Host Profile Data Block 5.3+
The Full Host Profile data block for version 5.3+ contains a full set of data describing one host. It has the format shown in the graphic below and explained in the following table. Note that, except for List data blocks, the graphic does not show the fields of the encapsulated data blocks. These encapsulated data blocks are described separately in Understanding Discovery & Connection Data Structures. The Full Host Profile data block a block type value of 149. It supersedes the prior version, which has a block type of 140.
Note
An asterisk (*) next to a block name in the following diagram indicates that multiple instances of the data block may occur.
The following diagram shows the format of the Full Host Profile data block for 5.3+:
