ServiceNow Service Mapping Basics

Introduction

This tutorial will guide you through the basics of ServiceNow Service Mapping. You will learn how to discover the service map of a two-tier Java-based web application, understand different types of service maps, and see how pattern-based discovery is utilized. This knowledge is essential for effectively managing application services in ServiceNow.

Step 1: Understand Service Mapping Basics

• Service mapping is a process that identifies and maps the relationships between application services and the underlying infrastructure.
• It helps organizations visualize their service architecture and improve the management of IT services.
• Key components of service mapping include:
  • Application services: The software components that deliver business functionality.
  • Service maps: Visual representations of how these components interact and depend on each other.

Step 2: Explore Application Services and Types of Service Maps

• Application services can be categorized into different types based on their architecture and dependencies.
• Common types of service maps include:
  • Physical maps: Show the physical infrastructure and how it supports services.
  • Logical maps: Focus on the logical structure of services without detailing the physical components.
• Both types provide insights into service dependencies, which are crucial for incident management and change planning.

Step 3: Discover the Service Map for a Two-Tier Java-Based Web Application

• To discover a service map for a two-tier Java-based web application, follow these steps:
  1. Set up the MID Server: Ensure that the MID Server is properly installed and configured. Refer to the installation guide here.
  2. Initiate Discovery: Use ServiceNow to start the discovery process for the application.
  3. Monitor Progress: Check the discovery progress and ensure that all components are being accurately detected.
  4. Review the Service Map: Once the discovery is complete, review the generated service map for accuracy and completeness.

Step 4: Utilize Pattern-Based Discovery

• Pattern-based discovery is a method used to identify and map services automatically based on predefined patterns.
• This approach simplifies the discovery process by:
  • Reducing manual input and configuration time.
  • Allowing for rapid mapping of new or changing services.
• To implement pattern-based discovery:
  1. Define Patterns: Create patterns that represent the expected structure and behavior of your services.
  2. Run Discovery: Execute the discovery process using these patterns to identify application services.
  3. Validate Results: Ensure the discovered services match organizational expectations and standards.
