Hi @Rajesh77 ,

I have tried merging up and summarising few of the documentation, hope this helps you get an idea.

1. Discovery Range Set and Discovery IP Ranges

Discovery Range Set

A Discovery Range Set in ServiceNow is a logical grouping of IP ranges. It helps you to organize and manage the discovery process more effectively by grouping related IP ranges. This way, you can apply different discovery schedules, credentials, or probes based on the range set.

Discovery IP Ranges

Discovery IP Ranges are specific ranges of IP addresses that you want the ServiceNow Discovery to scan. You define these ranges to specify which devices in your network should be discovered.

Creating and Managing Discovery Range Sets and IP Ranges:

1. Navigate to: Discovery > Administration > IP Ranges

2. Click: New to create a new IP Range

3. Fill in the form:

   • Name: A descriptive name for the range.
   • IP Range: Specify the start and end IP addresses.
   • Range Set: Optionally, associate it with an existing Range Set.

4. Save the IP Range.

Example:

• Name: Data Center Servers
• IP Range: 192.168.1.1 to 192.168.1.255
• Range Set: Data Center Range Set

2. Reviewing Schedules and Discovery Logs

Reviewing Discovery Schedules

Discovery Schedules determine when and how often Discovery runs. You can configure schedules to run at specific times, intervals, and frequencies.

1. Navigate to: Discovery > Schedules

2. Here, you will see a list of all Discovery schedules.

3. To review or modify a schedule:

   • Click on the schedule name.
   • Review the details:
     • Name: The name of the schedule.
     • Run: Specifies how often the schedule runs (e.g., daily, weekly).
     • Active: Indicates whether the schedule is active.
     • IP Range Sets: The IP ranges included in this schedule.

4. To create a new schedule:

   • Click: New
   • Fill in the form:
     • Name: A descriptive name for the schedule.
     • Run: Set the frequency (e.g., Daily at 2:00 AM).
     • IP Range Sets: Select the Range Sets or IP Ranges to be included.
   • Save the schedule.

Reviewing Discovery Logs

Discovery Logs provide detailed information about the Discovery process, including which devices were scanned, what was discovered, and any errors or issues encountered.

1. Navigate to: Discovery > Status

2. Here, you will see a list of all Discovery statuses.

3. To review a specific Discovery run:

   • Click on the Discovery status you want to review.
   • Review the details:
     • Status: Indicates if the discovery was successful, partially successful, or failed.
     • Duration: How long the discovery took.
     • Discovered Devices: List of devices discovered during the run.
     • Errors: Any errors encountered during the discovery.

4. To view logs for a specific device:

   • Click on the device name under Discovered Devices.
   • Review the device-specific logs and details.

Summary

• Discovery Range Set: A logical grouping of IP ranges.
• Discovery IP Ranges: Specific ranges of IP addresses to be scanned.
• Reviewing Schedules: Navigate to Discovery > Schedules, review, and configure schedules.
• Reviewing Logs: Navigate to Discovery > Status, review discovery run details and device-specific logs.

Thanks.

Hope it helps.
