Q-Advisor Architecture and Overview

Graphical User Interface is browser based for easy access from anywhere on the network.

Multiple access, user/group/password security for tests and result data.

RedHat Enterprise Linux 5 Operating System

MySQL 5 Relational DataBase

Scalability is ensuredSOAP/XML Northbound and Southbound interfaces for integration with other systems.

Flexible collection of results from multiple tests and sources—low impact on the network.

The Main Menu Bar consists of drop down menus organized by function:

• System Admin: All tasks necessary to configure and manage the Q-Advisor

• Q-Probe: All tasks necessary to configure and manage the network probes

• IPTV: All tasks necessary to create and run IPTV tests, and manage the results

• VoIP/SIP: All tasks necessary to create and run VoIP and SIP tests, and manage the results

• Data: All tasks necessary to create and run Data tests, and manage the results

Note: The IPTV, VoIP/SIP and Data menus follow the same structure and are self-containedSymmetricom offers separate QuickStarts for the IPTV, VoIP/SIP, and Data applications

Network Probe Activity

Select Q-Probe>Managementto see the status of the network probes.

You can configure a test using any network probe that

shows a status of UP.

Additional information on thenetwork probes is available by clicking on the link.

Network Probe Updates

Network Probes are remotely managed and updated. To update the Network Probe Software:

Select all the Network Probes to be updated, using the check boxes

First, browse to the “Application” update file on your workstation, named:netapp-4.0.0000xx-tar.gz select it, and hit the button

After approximately one minute, the network probe will automatically restart(verify by the network probe Status changing from DOWN to UP)

Next, browse to the “Kernel” update file on your workstation, named:kernel-4.0.0000xx-tar.gz select it, and hit the button

Finally, reboot the Network Probe by hitting the button.

Verify the changes by clicking on the link, and checking the Application and Kernel Version Numbers.

13

Network Probe Discovery

To find the probes, pick Q-Probe>Discovery from the menu bar.

Enter the IP address range for the probes. Note: subnet masks will allow the discovery of multiple probes.

Click Start Auto-Discovery.

Q-Advisor will discover the Q-xxx Network Probes, display them as they are found, and stop by itself.

Set the Q-Advisor's Local Time

Log into the Q-Advisor (shell, not GUI) as root.

Navigate to /usr/share/zoneinfo (cd /usr/share/zoneinfo ).

Select the continent and city pair that best matches your location, such as Europe and Roma.

Copy the time zone to the system. For example, for Europe and Roma, enter cp /usr/share/zoneinfo/Europe/Roma /etc/localtime

Update the java environment by completing the following:

Add the time information to the /etc/profile file. For example, for Europe and Roma, enter export TZ=“Europe/Roma"

Enter the following to execute the change: . /etc/profile service tomcat stop service tomcat start

Log into the Q-Advisor GUI, select System Admin > Setup >Q-Advisor; select Local vs. UTC Time; click the Update button.

Verify that the change occurred by checking the Server Date updated on your Q-Advisor (System Admin > Scheduler) is the easiest place to check

To change the local time in the Q-Advisor, use a monitor and keyboard, or a SSH (Secure Shell) connection, to the server and follow the steps below.

20

Backup the Q-Advisor Database

To backup the Q-Advisor database called qosmetrix_v40 in a file named backup:

Note: Make sure no test scenarios are running and all users are logged off before proceeding.

Using a keyboard and monitor, or an SSH connection to the Q-Advisor, log in as root.

At the # prompt, enter: # mysqldump –unetadvsr –pimedia123 qosmetrix_v40 > backup <Enter>

To restore a Q-Advisor database backup from a file named backup:

Prepare mysql first: # mysql –unetadvsr -pimedia123 qosmetrix_v40 -A <Enter>mysql> drop database qosmetrix_v40 <Enter> mysql> create database qosmetrix_v40 <Enter> mysql> quit <Enter> Bye

Then, perform the restore:# mysql –unetadvsr –pimedia123 qosmetrix_v40 <backup <Enter>

21

Change the IP Address for Eth0

Login in as root

Enter cd /etc/sysconfig/network-scripts

Enter vi ifcfg-eth0

In the eth0 file, change the network, netmask, gateway, and IP address as required for your network. The following shows example entries:

DEVICE=eth0#BOOTPROTO=dhcpBOOTPROTO=staticONBOOT=yesBROADCAST=10.100.255.255IPADDR=10.100.17.230NETMASK=255.255.0.0NETWORK=10.100.0.0GATEWAY=10.100.0.1

Save the file, and then restart the network:

service network restart

NOTE: You’ll need to use a monitor, keyboard, and vi editor to complete this procedure.
