SunNet Manager and Enterprise Manager Appendix 2: Defining Tables from Your Own

Schema Files

To read data logged by SunNet Manager using a schema file not supported by IT Service Vision, you must first create IT

Service Vision dictionary entries for the tables of metrics defined in the schema file using the %CSSNMSCH and %CPDDUTL

macros. Run these macros iteratively to create suitable definitions in your PDB for the tables in the schema file.

See the IT Service Vision Macro Reference documentation for instructions on using %CPDDUTL.

%CSSNMSCH Syntax

The %CSSNMSCH macro takes the following parameters:

%CSSNMSCH( schema=,

rpcids=,

snmnams=,

outfile= );

where:

schema= Name of input schema file to read

outfile= Name of output file to contain CPDDUTL statements

rpcids= Name of input file that contains RPC ID definitions

snmnams= Name of input file that contains SNM schema name definitions

Creating Dictionary Definitions from a Schema File

Creating IT Service Vision table definitions from a SunNet Manager schema file cannot be totally automated because of the

need for (sometimes) extensive input from the user. This input is in the form of interpretations of what the schema author had in

mind when he or she wrote the schema and provision of a mapping from long, schema variable names to short (less than 8

characters) IT Service Vision variable names. This sometimes results in the user having to edit the schema file and virtually

always means the user will have to manually enter the shortened variable names.

To create IT Service Vision dictionary definitions from a schema file, do the following:

1. Define RPC ids

RPC ids are used by SunNet Manager to map numbers to names (of tables). SunNet Manager uses the /etc/rpc file on

your system to determine how to log data.

Locate the /etc/rpc file on the host that runs SunNet Manager. Make a copy of it and edit it to make its format

resemble that of the example rpc id file !SASROOT/misc/cpe/csrpc.

Submit the %CSSNMSCH macro from the SAS PROGRAM EDITOR window to read your schema file

(presumably one not already supported by IT Service Vision) and the rpc file.

Again edit the copy of the rpc file to supply any missing values.

Loop through these steps until all ids are defined.

2. Map long variable names to short variable names

Schema files use names for tables and metrics. These names are too long for IT Service Vision. You must supply the file

that maps long names to short names and point the %CSSNMSCH macro to it.

Run the %CSSNMSCH macro against your schema file again. It will produce many messages about undefined

variable names.
