This documentation supports the 21.3 (12.3) version of BMC Discovery.


Viewing the discovery status

The status of the discovery and the reasoning process is displayed on the Home page in the Discovery Status summary.

The Discovery Status page is the central point for running discovery. The page contains the following sections:

Section nameDetails
Discovery summary

The summary panel displays the current status of discovery. Use this to diagnose where credential failures and transient failures are occurring, and to see where nodes are aging. Non-zero totals link to a list view page of the total. The following totals are displayed:

  • Successes—successfully scanned devices. If multiple node kinds are found, a multi kind list is displayed.
  • Transient failures—endpoints previously scanned for which there is one No Response or No Access discovery access result. When endpoints in this state are scanned again and there is another No Response or No Access discovery result, the endpoint is moved to the No responses category.
  • Credential failures—endpoints which can be contacted but for which the credential is invalid.
  • Identity changes—endpoints which appear to have changed identity.
  • No responses—endpoints previously scanned which are not responding and are aging out of the model. 
Tabs
  • Currently Processing Runs—Shows the first 10 runs that are in progress.
  • Recent Runs—Shows the 10 most recently completed runs.
  • Scheduled Runs—Lists scheduled runs.
  • Exclude Ranges—Shows the first 10 excluded ranges and enables you to add new exclude ranges.
Add New Run

Click to add a new snapshot or scheduled discovery run.

Add New Exclude

Click to add a new exclude range.

To view the discovery status

  • From the BMC Discovery main menu, click Manage > Discovery.
    The Discovery Status page displays a green RUNNING or a red STOPPED icon to show the current state. It also provides a START ALL SCANS button or a STOP ALL SCANS button, depending on whether BMC Discovery is running.

Important

By default, the discovery process is off. To start it, you must click START ALL SCANS. If a passphrase has been set on the credential vault, you must supply that before you can start discovery.

The following screenshot displays the default view of the Discovery Status page, where a passphrase is required before starting discovery.

Playback and record modes are for diagnostic support and testing. If one of these modes is in operation, a label is displayed on the right side of the page. For more information, see discovery settings

The following screenshot shows a sample Recent Runs tab on the Discovery Status page:

Consolidated discovery data

An appliance can be configured to be either a consolidation appliance or a scanning appliance. Consolidation refers to the centralization of discovery data from scheduled or snapshot scans on multiple scanning appliances, to one or more consolidation appliances. For a detailed description of consolidation, and how to configure it, see Consolidation.

Discovery status tabs

The Discovery page displays the status of various discovery scans. These scans can be currently running, completed, or scheduled to run at regular intervals. You can also view the range of endpoints that are excluded from scans. Each status is available in a separate tab, named as Currently Processing Runs, Recent Runs, Scheduled Runs, and Exclude Ranges. For information about the details available in each tab, click the required tab name listed below.

    The Currently Processing Runs tab shows the first 10 discovery runs that are in progress. The tab contains the following fields:

    Field name

    Details

    Label

    The descriptive label that is applied to the run by the user who created it.

    Started

    The scan start time. This time is when the discovery run was requested, rather than the actual start time. In practice, these times are almost identical; the only time that a large discrepancy is seen is when a discovery run is requested at the end or outside of a scan window.

    Outpost

    The medium through which the scan is performed. This can be one of the following:

    • ID of the Outpost used for the scan.
    • Local discovery, if the scan is performed from the local appliance (the discovery service).
    • Any, if you do not select a specific Outpost ID or Local discovery for scanning.

    Range

    The IP address range that is being scanned in this discovery run. For a large list of IP addresses, the range shows the first two IP addresses and the number of other IP addresses in the queue.

    Endpoints

    The total number of IP addresses being scanned in this discovery run.

    Type

    One of the following scans:
    • Open
    • Scheduled
    • Snapshot

    Level

    One of the following levels:
    Sweep Scan—Performs a sweep scan, trying to determine what is at each endpoint in the scan range. It will attempt to login to a device to determine the device type.
    Full Discovery—Retrieves all default information for hosts, and complete full inference.

    Percent Complete

    A progress indicator showing how much of the scan has been competed and how many are in progress.

    User

    The user name of the user who created the scan.

    If a discovery run is in progress but has been stopped because the scan window in which it can take place has ended, it is on hold. On hold scans are shown on the Currently Processing Runs tab and are marked as such.
    You can select a discovery run and cancel it using Cancel. The discovery run stops, although individual commands in progress continue to run to completion.

    For information about adding new discovery runs, see Performing a discovery run.

    The Recent Runs tab shows the 10 most recently completed discovery runs, and contains the following fields:

    Field name

    Details

    Label

    The descriptive label that is applied to the run by the user who created it.

    Outpost

    The medium through which the scan is performed. This can be one of the following:

    • ID of the Outpost used for the scan.
    • Local discovery, if the scan is performed from the local appliance (the discovery service).
    • Any, if you do not select a specific Outpost ID or Local discovery for scanning.

    Range

    The IP address range that was scanned in this discovery run.

    Endpoints

    The total number of IP addresses scanned in this discovery run.

    Timing

    The scan start time, finish time, and elapsed time. This time is when the discovery run was requested, rather than the actual start time. In practice, these times are almost identical; the only time a large discrepancy is seen is when the discovery run is requested at the end or outside or a scan window.

    Complete

    States whether the scan was completed or canceled by the user.

    Type

    The type of scan:
    • Open
    • Scheduled
    • Snapshot

    Level

    One of the following levels:
    Sweep Scan—Performs a sweep scan, trying to determine what is at each endpoint in the scan range. It will attempt to login to a device to determine the device type.
    Full Discovery—Retrieves all default information for hosts, and complete full inference.

    User

    The name of the user who created the scan.

    Actions

    A Rescan Now button is provided in this column, enabling you to rescan the discovery run. If you rescan a scheduled scan, it is scanned immediately as a snapshot scan with the same label.

    The Scheduled Runs tab shows up to 10 scheduled discovery runs, and contains the following fields:

    Field name

    Details

    Selection

    • Local discovery, if the scan is performed from the local appliance (the discovery service).
    • Any, if you do not select a specific Outpost ID or Local discovery for scanning.

    Range

    The IP address range to be scanned in this discovery run.

    Level

    One of the following levels:
    Sweep Scan—Performs a sweep scan, trying to determine what is at each endpoint in the scan range. It will attempt to login to a device to determine the device type.
    Full Discovery—Retrieves all default information for hosts, and complete full inference.

    Date Rules

    Describes the schedule for this discovery run: the days on which the discovery run takes place, the time it starts, and the period during which the scan is permitted to run.

    State

    The scan start time.

    Enabled

    Whether the scheduled run is enabled or disabled. Yes for enabled, No for disabled.

    Pattern Access

    Displays Yes or No depending on whether you selected or cleared the Public check box for an IP Address scan in a schedule. (Selecting the Public check box enables TPL patterns to initiate scans on IP addresses in the specified range.)

    User

    The name of the user who created the run.

    Created

    The date that the scheduled run was created.

    Actions

    A Scan Now button is provided in this column, enabling you to scan the discovery run. If you scan a scheduled scan, it is scanned immediately as a snapshot scan with the same label.

    You can enable, disable, or delete selected scheduled runs by using the EnableDisable, or Delete button at the foot of the table. See scheduled runs for more information about enabling and disabling scheduled runs. Disabling a scheduled run that is in progress cancels that run.

    For information about adding scheduled discovery runs, see Scheduling discovery runs.
