Performing a discovery run

You can start an immediate discovery or a scheduled discovery run by clicking the Add New Run link from the Discovery status page. You can perform the following actions for a run:

  • Specify the IP address or range to scan during a normal discovery run.

  • Specify if you want to perform the scan through a registered Outpost or the discovery service (local appliance). This is available only when you select the Targeting type as IP Address and an Outpost is installed and registered.
  • Specify the cloud provider for performing a cloud scan.

  • Schedule a discovery run to occur at any time and for a specified amount of time. For example, you might want to schedule a scan during off hours to avoid the risk of touching critical applications.
  • Enable or disable individual scheduled discovery runs.
  • Assign a company name to a discovery run.
For immediate runs, you can scan specified addresses or ranges immediately, whether or not a regular discovery run is in progress. The specified addresses or ranges are scanned automatically and as soon as possible. 

To perform a snapshot discovery run of IP addresses or ranges 

  1. On the discovery page, click Add New Run.



  2. Enter the information for the snapshot discovery run in the fields.

    Field name

    Details

    Label

    Enter a label for the discovery run. Where the discovery run is referred to in the UI, it is this label that is shown.

    Targeting

    Select the target for the discovery run. This is either:

    • IP Address — Enter IP address information.
    • Cloud — Enter cloud provider information.

    BMC Discovery extends the cloud scanning capabilities to cloud providers such as Microsoft Azure and Amazon Web Services.

    Range

    Enter IP address information in one of the following formats:
    • IPv4 address (for example 192.168.1.100). Labelled v4.
    • IPv6 address (for example 2001:500:100:1187:203:baff:fe44:91a0). Labelled v6.
    • IPv4 range (for example 192.168.1.100-105, 192.168.1.100/24, or 192.168.1.*). Labelled v4.

    Note

    Scanning the following address types is not supported:
    • IPv6 link local addresses (prefix fe80::/64)
    • IPv6 multicast addresses (prefix ff00::/8)
    • IPv6 network prefix (for example fda8:7554:2721:a8b3::/64)
    • IPv4 multicast addresses (224.0.0.0 to 239.255.255.255)

    As you enter text, the UI divides it into pills (discrete editable units), when you enter a space or a comma. According to the text entered, the pill is formatted to represent one of the previous types or presented as invalid.

    (info) Pills are not supported in Opera.

    Level

    Select one of the following levels:
    • Sweep Scan—Tries to determine what is at each endpoint in the scan range and attempts to log in to a device to determine the device type.
    • Full Discovery—Retrieves all default information for hosts, and complete full inference.

    Outpost

    (Available only when you select the Targeting type as IP Address.) Select whether you want to perform the scan through an installed Outpost or the local appliance. 

    The Outpost list displays only registered and enabled Outposts and the discovery service (local appliance). If you have not installed an Outpost and you scan only through the local appliance, this list does not provide options to choose.

    Ping

    Select a ping for the discovery run to be performed. This can be:
    • Use default—Default value to perform the discovery run.
    • Ping before scanning—Allows ping before scanning
    • Do not ping before scanning—Does not ping before scanning. This option should be selected for cloud discovery as public IP addresses do not respond to ICMP pings. All cloud scans would be dropped reporting no response.
    Session logging

    Choose whether to enable session logging for this scan. Session logging captures raw discovery data that can be used to diagnose discovery and data quality issues. The default is not to capture session logs.
    You need to capture session logs only when raising a case with Customer Support.
    This option is not available for Scheduled runs and Cloud scans. For information on viewing session logs, see If you encounter a problem.

  3. Click OK.
    The Currently Processing Runs tab is displayed with the new discovery run.

    Full Discovery—Retrieves all default information for hosts, and complete full inference.

    Outpost

    (Available only when you select the Targeting type as IP Address.) Select whether you want to perform the scan through an installed Outpost or the local appliance.

    Public

    (Available only for a Scheduled run, where the Targeting type is set to IP Address.) Select this check box to enable TPL patterns to initiate scans on IP addresses in this range. Patterns use the TPL discovery.scan function to scan the IP addresses. The IP address can be scanned by patterns even when the scheduled scan enabled time window is not in force.

    Frequency

    Select a frequency for the discovery run to be performed:
    Weekly by day of week
    Once per week
    Monthly by day of month
    Monthly by week of month

    Start

    Based on the selected scan frequency, different options are available to start scheduled scans. Discovery must be running at this time.
    Weekly by days of week—You are provided with buttons for each day and drop-down menus for the start time in hours and minutes. You can select one or more days from the day buttons. The selected buttons appear with a yellow border.
    Once per week—Select the day of the week and the start time in hours and minutes.
    Monthly by day of month—Select the day of the month and the start time in hours and minutes.
    Monthly by week of month—Select the week, the day of the week, and the start time in hours and minutes.

    For example, to start a scheduled weekly discovery run that starts on Friday at 19:30 hrs and continues until Saturday, do the following:

    1. Select the scan frequency as Weekly by days of week.
    2. Click the F and S day buttons.
    3. From the time drop-down menu, select 19 hours and 30 minutes.

    End

    You can end a scheduled scan when it is completed by selecting when completed.
    Alternatively, use the available option to end the scan which is based on the selected scan frequency. If the duration of the end time expires before the scan has completed, then the scan is suspended until the next scheduled time that the scan occurs. The scan resumes from the point at which it was previously suspended.
    Weekly by days of week—Select the end time in hours and minutes.
    Once per week—Select the day of the week and time to end the scan.
    Monthly by day of month—Select the day of the month and the time to end the scan.
    Monthly by week of month—Select the number of days and the time within which the scan must end.

    For example, to end a scheduled weekly discovery run that starts on Friday at 19:30 hrs and continues until 21 hours 30 minutes on Saturday (see the example for the Start field in the previous row), select 21 hours and 30 minutes from the Time drop-down menu.

  4. Click OK.
    The Scheduled Runs tab is displayed with the new scheduled discovery run.
  5. (Optional) To add another scan to the page, click Add New Run
  6. (Optional) To delete an existing scheduled scan, select the entry and click Delete.
