GenericSubversionStitcher

Overview

The Unified Assurance Topology Subversion Stitcher is used to create device relationships in the graph database using data gathered from a subversion repository. The stitcher connects to the given SVN repository, retrieves a file list and contents and makes it available to the rules files for special processing and entry into the graph database.

Subversion Stitcher Setup

  1. Update the URL in the configuration so the application connects to the correct subversion repository.

  2. Review the logic in the rules files referenced in the configuration to see the processing that will be done on the devices that are selected:

    • LoadRules will be run during application startup to load data that might be needed during processing.

    • IncludeRules will be read during application startup to load additional files that might be called during processing.

    • BaseRules will be run for each device that is selected based on the configuration.

    Update the logic as needed.

  3. Enable the default Service, unless a specific configuration option is needed:

    Configuration -> Broker Control -> Services

Rules

This application uses the Unified Assurance standard rules architecture in Perl syntax. For information about creating rules, see the following in Unified Assurance Developer's Guide:

Tokens

The stitcher exposes the following tokens for use in rules processing.

Token Description
$AppConfig Hash reference to the application configuration name-value pairs that were configured. (i.e. use $AppConfig->{'Host'} to retrieve the set value for 'Host'.)
$DataRow->{'BaseURL'} URL of repository (same value as $AppConfig->{'URL'}).
$DataRow->{'FileURL'} URL of current file.
$DataRow->{'FileContents'} Current file contents (results of the svn cat).
