Network Scan

Scan any IP range or specific set of IP addresses to discover assets and CIs across your network, using either credential-based or credential-less authentication.

Network Scan is the primary IP-based discovery method in ServiceOps. You define the scope (IP range or specific addresses), supply credentials, and ServiceOps connects to each device to collect asset data. You can run scans manually or schedule them to run automatically.

To access Network Scan, navigate to Admin > Discovery and Agents > Discovery > Network Scan.

Create a Network Scan

1. Click Create Network Scan. The following popup appears.

2. Enter the following details:

   Field	Description
   Name	Enter a name for the network scan.
   IP Range Type	Select the scope of the scan: Entire Network scans all IPs in the network (enter IP Range Start); Specific IP Range scans a defined range (enter IP Range Start and End); Specific set of IPs scans only listed addresses (enter IPs manually or import via CSV using the Import IP Addresses link).
   Authentication Preference	Select Credential-Based to scan using stored credentials, or Credential-Less to scan without credentials using Nmap. See Credential-Less Authentication for details.
   Location	Select the location of the network.
   Department	Select the department.
   Company	Select the company for which the network scan is to be created. This field is available only of Managed Services Provider (MSP) feature is enabled.
   Exclude IPs	Enter IP addresses to skip during the scan. Import excluded IPs in bulk using the Import Exclude IPs link.
   Protocol Type	Select Static or DHCP. If DHCP is selected, DNS configuration is required for Domain Scan.
   Description	Enter a brief description of the network scan.
   Credentials	Select the credentials for the machines you want to discover. Create new credentials inline using the Create Credentials link. New credentials are selected automatically.
   Poller	Select a Poller service to route the scan through that Poller.

3. Click Save. The scan appears on the list page. Now, you can configure a scheduler, or initiate the scan immediately using the Discover New Asset option or poll the existing asset. Once clicked, the discovery process will get initiated and the progress will appear on the Discovery Service page.

Actions on the List Page

After saving a network scan, the following actions are available from the scan row.

Scheduler

Select Scheduler on the scan row to configure automated discovery, polling, and ping runs for that scan. The scheduler popup displays three tabs:

• Discover Scan Schedule: Configure to automatically populate the inventory with newly discovered assets and CIs.
• Polling Scan Schedule: Configure to regularly poll existing assets and CI devices to monitor their status and update their details.
• Ping Schedule: Configure to check the active/inactive status and availability of assets and CIs.

Discover Scan Schedule

Click Create Discovery Schedule and configure the following:

1. Schedule Type: Select the type of schedule:
   • Once: Runs only once on the selected start date.
   • Daily: Runs daily from the selected start date and time.
   • Weekly: Runs once a week on the selected day and time. Provide a start date.
   • Monthly: Choose when the scheduler runs:
     • On Specific Date: Select the Date and Month for the schedule to run.
     • On Specific Day: Select the Occurrence (for example, first or second), Weekday (for example, Monday or Tuesday), and Month.
   • Interval: Set the interval in hours or days within which the schedule runs. Provide a start date.
2. Automatically add Assets in CMDB?: Select Yes to add discovered assets to CMDB automatically after each scan.
3. Email: Enter one or more email addresses to receive scan completion notifications.

Click Save to activate the schedule.

Polling Scan Schedule

Configure to regularly poll existing assets and CI devices to refresh their details. Click Create Polling Schedule and configure the following:

1. Schedule Type: Select the polling frequency:
   • Once: Polls only once on the selected start date.
   • Daily: Polls daily from the selected start date and time.
   • Weekly: Polls once a week on the selected day and time. Provide a start date.
   • Monthly: Choose On Specific Date or On Specific Day and configure the date, occurrence, weekday, and month accordingly.
   • Interval: Set the interval in hours or days. Provide a start date.
2. Email: Enter one or more email addresses to receive polling completion notifications.

Click Save.

Ping Schedule

Configure to check asset availability (active/inactive) on a recurring basis. Credentials are not required for ping scans. Click Create Ping Schedule and configure the following:

1. Schedule Type: Select the ping frequency:
   • Once: Pings only once on the selected start date.
   • Daily: Pings daily from the selected start date and time.
   • Weekly: Pings once a week on the selected day and time. Provide a start date.
   • Monthly: Choose On Specific Date or On Specific Day and configure accordingly.
   • Interval: Set the interval in hours or days. Provide a start date.
2. Email: Enter one or more email addresses to receive ping completion notifications.

Click Save. All scheduled runs appear in the Discovery Service tab at the configured time. View results from the Completed Scan tab and View History once the scan completes.

Discover New Asset

Click Discover New Asset on the scan row to trigger an immediate import of newly added assets. A confirmation dialog appears asking "Do you want newly scanned Entities in Asset/CI list?"

Select one of the following options:

• Yes: Adds the newly discovered entities directly to the Asset or CI list, based on the configured Discovery Preference Rule.
• No, Add in Stage: Runs the scan but places discovered entities in Stage instead of the Asset or CI list.
• Cancel: Closes the dialog without running the scan.

note

This option is available for credential-based discovery only.

Poll Existing Asset

Click Poll Existing Asset to refresh the details of assets already in the system. ServiceOps reconnects to each known device and updates its recorded information.

note

This option is available for credential-based discovery only.

When polling completes, the Discovery Service page reflects the updated results.

Ping Asset

Click Ping Asset to scan the network and identify which devices are reachable. This does not collect asset details and does not require credentials.

Edit and Delete

Click Edit to update the scan configuration. Click Delete to remove the scan if it is no longer needed.

Add Asset in Stage

Select Add Asset in Stage to manually promote staged assets to CMDB. Select the asset type, choose the assets, and click Add to CMDB.

Add CI in Stage

Select Add CI in Stage to promote staged CIs to CMDB. Select the CI filter, choose the CIs, and click Add to CMDB.

Import IP Network

Use Import IP Network to bulk-import network scan configurations from a CSV or Excel file instead of creating each scan manually.

To access this feature, navigate to Admin > Discovery and Agents > Discovery > Network Scan and click Import IP Network on the list page. The IP Network Batches page appears, listing all previous import batches.

Click Import Batch. The Import Batch panel appears with two steps: Upload CSV and Map Fields.

Configure the following in Step 1: Upload CSV:

1. Import File Type: Select CSV or Excel as the file format.
2. IP Range Type: Select the IP range type for all scans in this import:
   • Entire Network: Scans all IPs in the network starting from the IP Range Start address.
   • Specific IP Range: Scans a defined range between the IP Range Start and IP Range End addresses.
   • Specific Set of IPs: Scans only the specific IP addresses listed in the import file.
3. Upload CSV: Download the sample CSV file using the Click here link to see the expected column format. Prepare your file in UTF-8 format with field names in the first row.
4. Select CSV: Click Select CSV to upload your prepared file.
5. Click Next to proceed to the field mapping step.

The sample CSV file contains the following columns:

Column	Description
Name	Name of the network scan.
IP Range Start	Starting IP address for the scan range.
Location Name	Location to assign to discovered assets.
Department Name	Department to assign to discovered assets.
Protocol Type	Protocol type for the scan, for example Static.
Authentication Preference	Set to Credential-Based or Credential-Less.
Description	Brief description of the network scan.
Credentials Name	Name of the credentials to use for the scan.
Exclude List of IP	Comma-separated list of IPs to skip during the scan.
Poller	Poller service to route the scan through.

After the import completes successfully, the batch appears on the IP Network Batches list page with the status, total records, success count, and failure count.
