Viewing discovery status

The status of the discovery process is shown on the Home tab in the Discovery Status summary. This shows the current status of the discovery and reasoning process.

Click Discovery is currently by the green RUNNING or red STOPPED button to display the Discovery Status page.

In order to start the discovery process, you must click START ALL SCANS, as by default discovery is off.

The Discovery Status page

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

The Discovery Status page also provides a START ALL SCANS button or a STOP ALL SCANS button depending whether discovery is running or not. The default view of the Discovery Status page, with a snapshot scan in progress, is shown in the following screen.
This screen illustrates the default view of the Discovery Status page.

Consolidation

An appliance may 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 about consolidation and how to configure it, see Consolidation.

Currently Processing Runs

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

Field Name

Details

Label

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

Started

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

Range

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

# of IPs

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

Type

The type of scan. This is one of:
• Snapshot
• Scheduled

Level

The level for the discovery run. This is one of:
Sweep Scan: This will do 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: Retrieve all the default info 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 in the Currently Processing Runs tab and marked as such.
You can select a discovery run and cancel it using Cancel. The discovery run will stop though individual commands in progress will run to completion.

Adding new discovery runs is described in Controlling discovery.

Recent Runs

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. This is the label applied by the user who created the run.

Range

The IP range that was scanned in this discovery run.

# of IPs

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

Timing

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

Complete

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

Type

The type of scan. This is one of:
• Snapshot
• Scheduled

Level

The level for the discovery run. This is one of:
Sweep Scan: This will do 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: Retrieve all the default info 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 which enables you to rescan the discovery run. If you rescan a scheduled scan, it is scanned immediately as a snapshot scan with the same label.

Scheduled Runs

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

Field Name

Details

Label

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

IP Range

The IP range to be scanned in this discovery run.

Level

The level for the discovery run. This is one of:
Sweep Scan: This will do 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: Retrieve all the default info 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 in which the scan is permitted to run.

State

The scan start time.

User

The name of the user who created the run.

Created

The date that the scheduled run was created.


Adding scheduled discovery runs is described in Scheduled Discovery Run.

Exclude Ranges

The Exclude Ranges tab shows the ranges which have been specified as not to be scanned, and contains the following fields:

Field Name

Details

Label

The descriptive label that was applied to the exclude range.

Range

The IP range that is not to be scanned in any discovery run.

Description

A description for the exclude range.

User

The user who created the exclude range.


Adding new exclude ranges is described in Exclude Ranges.

Topology Runs

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

Field Name

Details

Label

The descriptive label that was applied to the topology run.

Completed/LANs

The number of LANs which have been processed and the total number to be processed.

Timing

A description for the exclude range.

State

The current state of the run. This may be Processing, Complete, or Canceled.

User

The name of the user who created the run.


Adding a new topology run is described in Adding a topology run.

    Topology Run tab described here is not present in 8.3SP1 as that functionality's being replaced by Edge Switch connectivity feature.
