Discrepancy detection is the process of comparing discovered data with imported data and enumerating any differences between the sets of data.

The discrepancy detection process is part of a scan configuration. You can configure a manual scan or a scheduled scan that detects discrepancies.

To configure a scan to detect discrepancies, create or configure a scan and select the Detect Discrepancies option when defining scan properties. The discrepancy detection process will start at the conclusion of the scan on which it is enabled. See "Defining Scan Properties" for more information.

You can configure discrepancy detection on import scans, discovery scans, or assimilation scans. Because discrepancy detection compares data, ensure that you enable discrepancy detection on the last scan before your scan data is complete.

For example, if you are planning to run an import scan, followed by a discovery scan, followed by an assimilation scan, configure the assimilation scan with the Detect Discrepancies option selected.

The results of the discrepancy detection process are displayed in the result of a scan. To view the discrepancy detection progress report, click the scan you wish to view in the Manage Scans table. The Scan Status information is generated in the final section of the Manage Scans table, and is divided into three separate reports:

• Scan Progress

• Discrepancy Detection Progress

• Discrepancy Counts

See "Viewing a Scan Status" for more information on the Scan Progress report.

• Total displays how many times the discrepancy detection process has been run (the scan may also be in progress).

• In Progress shows whether the discrepancy detection process is currently running. If this value is zero, this scan is not currently running.

• Completed displays the number of discrepancy detection processes that have run successfully.

• Error lists the number of discrepancy detection processes that have run unsuccessfully.

  To investigate discrepancy detection failures, refer to the server logs from the Network Integrity application. See Network Integrity System Administrator's Guide for further information about logging.

  The designer of the cartridge pack should also be able to provide information about the cause of these errors.

• Critical lists the discrepancies with a severity of critical. This is the highest discrepancy severity.

• Major lists the discrepancies with a severity of major.

• Minor lists the discrepancies with a severity of minor.

• The Progress bar, in blue, shows the progress of the discrepancy detection process in percentage terms. When it reaches 100 per cent, the status changes to Completed.

• Start Time displays the time at which the discrepancy detection process commenced. The time is displayed in the format YYYY-MM-DD HH:MM:SS, and specifies the local time zone and year; For example, 2009-03-12 04:13:00.

• End Time displays the time at which the discrepancy detection process ended. The time is displayed in the format YYYY-MM-DD HH:MM:SS, and specifies the local time zone and year; For example, 2009-03-12 04:18:24.

• Duration lists the time taken for the discrepancy detection process to complete. The time is displayed in the format (DD) (HH) MMm SSs; For example, 5m 24s.

• Warning lists the discrepancies with a severity of warning. This is the lowest discrepancy severity.

To review the discrepancies discovered during a scan:

• Select Review Discrepancies from the list of tasks.

• Select View Latest Scan Results from the list of tasks. From the Scan Results page, select a scan in the Search Results table.

  Click the Review Discrepancies tab.

• Select Manage Scans from the list of tasks. From the Manage Scans page, select a scan in the Search Results table.

  Click the Review Discrepancies tab.
