NetIQ Performance Endpoints

Vivinet Assessor ships with NetIQ Performance Endpoint version 5.1. Performance Endpoints are software agents that must be installed on any computer you plan to include in VoIP Quality assessments.

The endpoint software is not required to run a Network Inventory, to assess device and link utilization and configuration, or to perform Bandwidth Modeling.

Endpoints can be installed in a matter of minutes. Users on the network to be assessed can easily install the software on their desktop computers. You can download it from the Performance Endpoints page, or you can make it available for installation from a central server. Endpoint documentation, including complete installation instructions, is provided at the same Web page.

NetIQ Corporation periodically updates the endpoint software to include more functionality. The latest endpoint software is available free at the Performance Endpoints page.

Known Issues

NetIQ Corporation strives to ensure our products provide quality solutions for your enterprise software needs. Vivinet Assessor had the following known issues at the time of release. If you need further assistance with any issue, please contact Technical Support.

  • Accessing the Vivinet Assessor Console remotely with Windows Remote Desktop Services can cause the CPU usage of the Assessor Console to go to 100%. This problem has been encountered only on the Assess VoIP Quality > Design window, and only if you manipulate the Design window, such as if you use the mouse to manually stretch the window or change its shape. To avoid the problem, click Maximize on the Assessor window instead of using the mouse to resize the window. (ENG311356)
  • Error when attempting to export an assessment. You might receive an error message if you try exporting an assessment that the backup device cannot open. A sample error message could be: "Operating system error 5 (Access is denied)." To address this issue, before you export an assessment to a folder on your computer, ensure that the SQL Server 2005 Express service account has write permissions to that folder. The default SQL Server 2005 Express service account is Network Service. (DOC253598)
  • Installation cannot run from network share. You cannot install Vivinet Assessor from a network share. You must copy it to a local directory on your hard drive. If you downloaded the package, simply extract the contents of VivinetAssessor.exe to a local directory. If you have a copy of the Vivinet Assessor installation CD, copy the entire CD file structure to a local directory. Then install Vivinet Assessor. For more information, see the chapter titled "Installing and Registering Vivinet Assessor" in the Vivinet Assessor User Guide.
  • SNMPv3 might spike CPU usage. Discovering or monitoring network devices using SNMPv3 might produce a temporary spike in processor usage. SNMPv3 requires additional overhead for authentication or encryption of query requests sent to the SNMP agent on the devices.
  • Multiple reports generated simultaneously might raise errors. Reports are generated in Microsoft Word and Excel. If you try to generate more than one report at a time from multiple assessments, you might receive an error message.
  • Illegible characters might appear in Japanese-language reports. These characters are formatted in the wrong Microsoft Word font. If you see any illegible characters in reports generated with the Japanese language support, first highlight the characters. Then click Format > Font and choose a Japanese (Kanji) font from the Font list.
  • "100% Unavailable" might appear in results for the most recent run or verification. Run the verification again, or allow the assessment run to continue to the next set of calls. If endpoints are still unavailable, you might have a DNS problem in your network, or you might have typed a hostname incorrectly.
  • Insufficient privileges error when installing Vivinet Assessor. If the Windows Services Control Panel is open when you are installing Vivinet Assessor, you might receive a Windows error message asking that you verify you have sufficient privileges to install system services. If you receive this error message, close the Control Panel, wait a few seconds, and then retry the installation. If you receive this error message when the Control Panel is not open, you must log on with sufficient administrative privileges.
  • Installer prompt appears during upgrade. When you run the installation program to upgrade your version of Vivinet Assessor, the installer prompts you to close all open programs and displays their names in a list. In most cases, you can safely click the Ignore button and let the installation continue with the programs open. However, the Vivinet Assessor Console and the Analysis Console should always be closed before performing an upgrade.

Hotfix 72175, April 2010

This release resolved the following issues:

  • SNMP error occurs during network inventory discovery. This release resolves an issue in which SNMP requests attempt to use IPv6 MIBs, which are not included with Vivinet Assessor. With this release, Vivinet Assessor ships with IPv6 MIBs, which are installed by default in the Vivinet Assessor\MIBs folder.
  • Cisco switches do not respond to SNMP requests. This release resolves an issue in which Cisco IOS Software Release 12.2(40)SG, for Cisco Catalyst 4900 Series switches, does not respond to SNMP GET or GETNext requests. The SNMP requests fail because they use MIBs that Cisco no longer supports: ifInNUcastPkts and ifOutNUcastPkts. With this release, Vivinet Assessor SNMP requests use newer MIBs that Cisco does support: ifInMulticastPkts, ifInBroadcastPkts, ifOutMulticastPkts, and ifOutBroadcastPkts.

Hotfix 72033, March 2010

This release provided the following enhancements:

  • Support for Microsoft Office 2007. Microsoft Word and Excel are required for generating and printing reports. Vivinet Assessor now supports Microsoft Office 2000, 2002 (Office XP), 2003, and 2007. Earlier versions are not supported.
  • Support for Microsoft Windows 7. With this release, you can install Vivinet Assessor on computers running Windows 7.

Hotfix 71135, January 2009

This release resolved the following issues:

  • SQL Server Express installation fails when service names are non-English. Before you install this release, the installation of Microsoft SQL Server 2005 Express fails on Windows computers with locales set to a language other than English. After you install this release, the installation process uses the default SQL Server 2005 Express services accounts, enabling the installation of Vivinet Assessor to proceed. (ENG242285)
  • No verification when assessment is too large. Before you install this release, Vivinet Assessor does not advise you when your assessment is too large for the capacity of the SQL Server 2005 Express database. Your assessment eventually fails. After you install this release, when you click the Verify button, Vivinet Assessor immediately notifies you when your assessment is too large. (ENG245854)
  • Installation on Windows Server 2008. Before you install this release, the prerequisite checking feature prohibits installation of the application on Windows Server 2008. After you install this release, you can successfully install Vivinet Assessor on Windows Server 2008. (ENG253166)
  • Device utilization always 100% unavailable for supported devices. Before you install this release, Vivinet Assessor might not be able to gather utilization statistics for devices that are generally supported by the product because of a lower default PDU size setting on those devices. This results in a utilization assessment of 100% unavailability for these devices. After you install this release, Vivinet Assessor accommodates these lower PDU size settings in its queries of the devices, enabling it to successfully gather utilization statistics. (ENG249161)

This release also provided the following enhancement:

  • Support for a blank context in SNMP version 3. With this release, you can configure SNMP permissions for devices that do not support context. For more information, see the "Setting up a Network Inventory" topic in the User Guide for Vivinet Assessor, included in the download package and also available at the Vivinet Assessor Documentation page. (ENG249452)

  • Microsoft SQL Server 2005 Express. SQL Server 2005 Express is automatically installed when you install Vivinet Assessor 3.3.

  • Additional granularity for call duration. You can now specify call durations of less than one minute in VoIP Quality assessments.
  • SNMP version 3. This version of Vivinet Assessor provides support for monitoring devices using SNMP (Simple Network Management Protocol) version 3.0. New fields in the Edit SNMP Configuration dialog box allow you to specify SNMP v3 permission information. For more information, see the User Guide for Vivinet Diagnostics or the Help for the Edit SNMP Configuration dialog box.
  • Filtering of Ethernet links during Network Inventory. New fields in the Inventory Network Set Up view and the Add to List of Discovery Ranges dialog box let you specify ranges of Ethernet network interface port numbers to limit the number of Ethernet links that are discovered.
