Poetry

Clone the repository and run:

poetry install

Overview

The ipfabric-snow integration is a powerful command-line tool designed to facilitate the synchronization of network inventory data between IP Fabric and ServiceNow. This Python application is built with minimal dependencies, ensuring ease of setup and maintenance. Key features and requirements of this tool include:

  • Staging Table Requirement: ipfabric-snow requires a staging table in ServiceNow. This table acts as an intermediate location where data from IP Fabric is temporarily stored before being processed or transferred to the final destination table. In ServiceNow, this is referred to as a import set. Reference ServiceNow’s documentation on import sets.
  • Transformation Maps: The integration utilizes transformation maps, a component in ServiceNow, to map and transform data fields from IP Fabric to corresponding fields in ServiceNow. See ServiceNow’s documentation on transformation maps.
  • Diffing with CMDB Network Gear Table: The main functionality of ipfabric-snow is its ability to perform differential analysis between the data in IP Fabric and the existing data in ServiceNow’s CMDB (Configuration Management Database) network gear table. This feature allows users to identify and synchronize any discrepancies between the two data sources.
  • Command-Line Interface: ipfabric-snow is a command-line utility, offering a user-friendly interface with various commands and options. This approach makes it versatile for different environments and use cases, allowing automation and scripting.
  • Dry Run Feature: Supports a “dry run” mode, which allows users to simulate the synchronization process without making actual changes.
