About VoIP Monitoring Manager

VoIP Monitoring Manager is a Voice over IP (VoIP) Quality of Service (QoS) monitoring tool. It
enables you to monitor and review the quality of a call on an AVAYA™ VoIP network. Using the VoIP Monitoring Manager, you can view the Jitter, Round Trip Time (RTT) and Packet Loss experienced at the endpoints and during a session. The QoS data displays currently active endpoints or for endpoints active in the past. With this information, you can begin to troubleshoot and isolate problems.
If you are new to using the VoIP Monitoring Manager, the following information explains what you can do with this tool.

Search for Endpoints

You search endpoints active from some time in the past or within a date range. The Advanced Search options enable you to narrow your search to match phone numbers, SIP user names, network addresses, or QoS level.

View Reports

Once you have completed your search, you can view a summary or a detailed report. The reports display the QoS data for selected endpoints. This is particularly useful for monitoring Gateways or locating problems at a particular endpoint. You can also view a report for endpoints involved in a session. This will assist with determining problems that occur between two endpoints or in an isolated area of the network.

Generate Automatic Alarms

You can generate SNMP Traps/Alarms , which enables the VoIP Monitoring Manager to alert you when the Jitter, Round Trip Time or Packet Loss reaches certain levels. This assists you to routinely monitor the network, and troubleshoot problems.

About VoIP Monitoring Manager Client

The VoIP Monitoring Manager (VMM) Client provides the graphical user interface (GUI) for VoIP Monitoring Manager. The VMM Client does not communicate with the VMM RTCP Monitor and does not use SNMP. The data that is displayed is gathered from the VoIP Monitoring Manager (VMM) Server.
The VMM Client may be installed on the same machine as the VMM Server, or it may be installed on another machine on the network. It is possible for the VMM Server and the VMM Client to communicate over a dial-up connection.

About VoIP Monitoring Manager Web Client

The VoIP Monitoring Manager (VMM) Client can run as a web application in a browser. This is useful if you only have the VMM Server installed.
The VMM Server needs to be running a web server. If you purchased Avaya Integrated Management, the Apache web server will already be installed and running. If you choose to run the Apache web server, the VMM installation will assist with configuration. The machine running the VMM Web Client needs to have the Sun Java Plug-in installed to run the Web Client.
Configure the web server to publish the file to the following default install path:
C:\Program Files\Avaya\VoIP Monitoring Manager\jars\ClientApplet.htm
If you run the web client you will not have access to all the functionality available in the application. This includes features such as copy and connect to a new server. For more information see Starting VoIP Monitoring Manager Web Client.

About VoIP Monitoring Manager Server

The VoIP Monitoring Manager Server acts as a proxy between the VoIP Monitoring Manager Client and the VoIP Monitoring Manager RTCP Monitor. The main purpose of the VoIP Monitoring Manager Server is to reduce the amount of traffic to the VoIP Monitoring Manager Client by performing large data downloads and extensive processing of the MIB data stored on the RTCP Monitor. The VoIP Monitoring Manager Server can reside on the same PC as the RTCP Monitor.

Components of VoIP Monitoring Manager

The VoIP Monitoring Manager (VMM) application comprises the VMM RTCP Monitor and the VMM Server, which accepts connections from the VMM Client. If you only have the VMM Server installed, you can run VMM Client as a web client.
To ensure it will run correctly, you will need to have configured the Switch Administration Forms, have a Windows SNMP Agent installed on the Server and the Monitoring Manager Server needs to be installed onto the network.
The components and their relationship are described in more detail in the following links:
VoIP Monitoring Manager Server  VoIP Monitoring Manager RTCP Monitor  VoIP Monitoring Manager Client  VoIP Monitoring Manager Web Client  Database

About Licenses

VoIP Monitoring Manager requires licenses that you must purchase from Avaya. You can purchase these licenses in sets of 2000 phone endpoints and 40 media gateways. The Avaya licenses are managed by the WebLM server, which is provided with VoIP Monitoring Manager.
By selecting Help>About in the VMM Server or the VMM Client, you can view the following information:
the number of licenses purchased  the number of phones at the local server. This number represents the phones that
reported to VMM in the last 28 days. This number will increase if you move phones (for example, change extensions or IP addresses). In this case, these phones appear to be new endpoints to VMM. Since there is a 30-day grace period, this will not be a problem.
the number of phones at the local server that exceed the license (that is, the number of
phones that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more phones stored in the database than licenses purchased.
the number of media gateways at the local server. This number represents the media
gateways that reported to VMM in the last 28 days.
the number of media gateways at the local server that exceed the license (that is, the
number of media gateways that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more media gateways stored in the database than licenses purchased.
Each VMM RTCP monitor periodically checks the number of endpoints it knows about and requests/renews the licenses for them. If there is more than one RTCP monitor and the total number of endpoints known exceeds the number of licenses, the RTCP monitor that requests licenses first will get its licenses. The RTCP monitor that requests licenses last will be denied licenses. If you enter the 30-day grace period because license limits were exceeded, the About dialog box will appear every time the VMM Server and VMM Client are started. If you exceed the 30-day grace period, VoIP Monitoring Manager stops collecting RTCP data.
Avaya provides a 90-day trial version of VoIP Monitoring Manager. After 90 days, VoIP Monitoring Manager stops collecting RTCP data. You have the option of purchasing the VoIP Monitoring Manager license key from Avaya to fully activate the VoIP Monitoring Manager beyond the 90-day trial period. When a license key is purchased, an instance of WebLM License Server is required to manage the license key.
Contact your authorized Avaya Sales Representative to purchase additional VMM licenses.

Installation Checklist

Installation Checklist

The VoIP Monitoring Manager Server (VMM Server) needs to be installed on the VoIP network. Before you install the software, you need to configure the Switch Administration Forms.
1. Configure Switch Administrator forms
You need to configure the System-Parameters IP-Options Form and the IP-Network­Region Form to send RTCP reports to the RTCP Monitor.
2. Make one port 1099
The VMM Client and Server communicate using Java Remote Method Invocation (RMI), and uses port 1099 as its default port on the machine running the VMM server. If port 1099 is not available, another port must be made available.
3. Check for Windows SNMP Agent
The SNMP Agent must be installed for the VoIP Monitoring Manager Server to function. You can check if the Windows SNMP Agent has been configured to run at startup automatically. The installation also checks to see if the Windows SNMP Agent is installed.
If the Windows SNMP Agent is not installed, the Add/Remove Windows Components starts automatically and you are be prompted for the Windows 2000 CD location to install the Windows SNMP Agent.
4. Check for a valid SNMP Community ID
You must set an ID with the correct privileges.
5. Configure SNMP agent for sending traps
Although SNMP is installed and running, it dies not send the required traps until you configure it.
6. Download VoIP Monitoring Manager or Install from CD
If you are downloading the program from a web site, select to Run this program from its current location and the installation program starts automatically. Alternatively, you can
select to save the file to disk, which may be the faster option. Once saved to your hard drive, double-click the saved program's name to start the install. If you are installing the program from a CD-ROM, insert the CD into your drive and follow the instructions.
7. Connect to a database
When you first install VoIP Monitoring Manager, you need to connect Server to a database.
Solving Installations Problems: If you are experiencing difficulties running the application after installation the following checks may assist you:
Check Windows SNMP Agent is Running  Check for a Valid Community ID

Configure IP-Network-Region form

There are two Switch Administration Forms (SAT) that need to be configured to send RTCP reports to the RTCP Monitor. These forms are called the ip-network-region form and the system­parameters ip-options form.
Configuration for the ip-network-region form
Set the RTCP Reporting Enabled? field to y (yes).  Set Use Default Server Parameters? field to y (yes). This indicates that this network
region uses the default values specified previously on the system-parameters-ip-options form as well.
Why you might not want to use the default parameters?
Multiple VoIP Monitoring Manager Servers might be installed on a large system in order to reduce the network traffic between a set of endpoints and the RTCP Monitor (e.g. low bandwidth link between endpoints in one network region and a remote RTCP Monitor). The network traffic due to RTCP reports being sent from the endpoints to the RTCP Monitor is usually low, less than 40 bytes per second per currently active VoIP call (RTP session). Therefore, it is usually unnecessary to have multiple RTCP Monitors.
If multiple VoIP Monitoring Manager Servers are installed on the system then the endpoints in each network region can be configured to send their RTCP reports to different RTCP Monitors.
To achieve this set the Use Default Server Parameters? field to n (no) and specify the IP address of the Windows 2000 PC running the VoIP Monitoring Manager Server for that network region.

Make one port available

The VMM client and server communicate using Java Remote Method Invocation (RMI), and uses the port 1099 on the machine on which the VMM server is running.
If this port is not available, the VMM server will attempt to use the following ports: 49177, 51173, or 63006. Although it is unlikely that all of these ports will be in use on a single machine, please ensure that at least one of these ports is available.

Check Windows SNMP Agent is Installed and Running

The Windows SNMP Agent must be installed before you install the VoIP Monitoring Manager Server. You are prompted during the VoIP Monitoring Manager install to install it from the Windows 2000 CD. If the Windows SNMP Agent is not installed or not running, you will experience problems receiving data.
Check if Windows SNMP Agent is Installed and Running
1. Select Start > Settings > Control Panel > Administrative Tools > Services.
2. Scroll down until you see the words SNMP Service. It should have a status as Started and Startup Type as Automatic. If it is not included in the list you will need to install it from the Windows 2000 CD.
3. If it is listed but not set to run automatically, you will need to change its properties as follows:
4. Right-click on SNMP and select Properties from the context menu. The SNMP Service Properties dialog opens.
5. Select Automatic from the Startup Type drop down list.
6. Click OK.
