Populate and maintain your CMDB with ServiceNow Discovery

Gain deep infrastructure visibility with reliable data from ServiceNow Discovery

BEFORE YOU START, YOU NEED:
  • A designated IT admin overseeing the discovery process 
  • Intermediate understanding in Windows/Unix/Linux system administration 
  • Basic to intermediate grasp of networking principles such as IP routing
  • Ability to deploy and use primary network analysis tools 
  • Knowledge of configuration management methodology 
  • A ServiceNow Discovery license 
  • An understanding of configuration management plans

Introduction

Achieving complete visibility into your enterprise infrastructure requires reliable configuration data for physical and virtual servers, computers, routers, switches, applications, cloud instances, and more. This means you need an updated configuration management database (CMDB) at all times. Many organizations fail to keep their CMDB current due to the lack of an automated process that discovers network infrastructure and applications. Yet, when implementing more automated discovery processes, IT operations groups often fail to establish clear expectations with network, server, security, CMDB, and other groups. This leads to project delays.

A solid configuration management plan will help keep your CMDB healthy—and give you a solid foundation for implementing automated discovery. To set up an effective configuration management plan, see our best practice titled Plan your successful CMDB deployment.

In this best practice guide, you’ll learn how to set up ServiceNow® Discovery in a way that lets you keep your CMDB current and reliable. The guide explores how creating comprehensive goals and getting agreement from stakeholders helps you set the stage for success. You’ll also learn best practices for implementing your Management, Instrumentation, and Discovery (MID) servers and for establishing a credentials strategy and schedules. 

Terms and definitions

  • MID Server  Each MID Server is a lightweight Java process that can run on a Linux, Unix, or Windows server. During discovery, the MID Server executes probes and patterns and returns the results back to the instance for processing. It doesn’t retain any information.
  • Probes and sensors  Probes and sensors are scripts that collect data on the host, process it, and update the CMDB. Several probes and sensors are provided out of the box. You can also customize them or create your own. 
  • Patterns – These are a series of operations that also collect data on a host, process it, and update the CMDB. Patterns differ from probes and sensors in that they are written in Neebula Discovery Language (NDL) rather than JavaScript. You use them during the last two phases of discovery. Discovery comes with default patterns out of the box, but you can customize them or create new ones using the pattern designer.

Follow these four stages to achieve complete visibility into your infrastructure when you have reliable data in your CMDB.

Then, to optimize ServiceNow Discovery, set up recurring schedules that complete within your desired timeframe. In order to keep the CMDB current, define schedules for your on‑premises and cloud networks by geographic location or IP ranges.

Each MID Server is a lightweight Java process that can run on a Linux, Unix, or Windows server. During discovery, the MID Server executes probes and patterns and returns the results back to the instance for processing. It doesn’t retain any information.
