When you first start to use ITM, you may be interested in the answers to the following questions:
•
How Are ITM and ITM Multi-View Different?
ITM and ITM Multi-View both provide the features described in the "What Is ITM?" section. The differences between them are described in Table 1-1.
Table 1-1 Comparison of ITM and ITM Multi-View
Number of enterprises that you can manage from a single platform
One.
Up to ten.
Each enterprise is managed from a separate partition. A Partition Administrator assigns devices and users to partitions. Network Administrators and Network Operators log in to ITM and monitor devices in one partition. For more information on partitions, see the "What Is a Partition?" section.
User roles and security
Uses standard CiscoWorks user roles to control access to tasks. For more information on CiscoWorks user roles, see the "Understanding Your User Role" section.
Uses standard CiscoWorks user roles in addition to a unique CiscoWorks user role: the Partition Administrator. Only a Partition Administrator can manage partitions, assigning devices and users to them.
Although the Network Administrator and Network Operator user roles are granted permission to perform ITM tasks, they can do nothing if they have not also been assigned to a partition by a Partition Administrator.
Configuration tasks
You need only perform configuration tasks once with respect to the needs and situation of your enterprise.
A Network Administrator can perform any configuration task.
Each Network Administrator should perform configuration, as needed, taking into account the needs and situation of the enterprise in the active partition. Each Network Administrator might, for example, do the following:
•
•
There are certain configuration tasks that only a Partition Administrator can perform. See the "Tasks for Partition Administrators" section.
System administration
An admin user can back up, and restore, all ITM data.
An admin user can back up, and restore, all ITM Multi-View data. In addition, a Partition Administrator can save and restore the data for a partition.
Device monitoring
Users have access to information about any device ITM manages.
Users have access to information about the devices ITM Multi-View manages in one partition: the active partition.
Device management
After you add or import devices, ITM initiates discovery, begins polling, and starts to manage the devices.
The process is illustrated in the "Example: Importing a Voice Gateway into ITM" section.
After you add or import devices, ITM Multi-View moves the devices to the default partition and initiates device discovery. However, ITM Multi-View does not begin polling until a Partition Administrator assigns the device to an active partition.
The process is illustrated in the "Example: Importing a Voice Gateway into ITM Multi-View" section.
IP phone information1
Users have access to information about phones that ITM discovers.
Users have access to information about phones that:
•
•
1 IP phone information is available only if you have downloaded and installed Incremental Device Update (IDU) 2 or later from the ITM download site: http://www.cisco.com/pcgi-bin/tablebuild.pl/item-3des.
Example: Importing a Voice Gateway into ITM
Figure 1-1 shows the series of activities that ITM performs when a user imports a voice gateway, including showing how a user can confirm that these activities have occurred. To see the same example illustrated for ITM Multi-View, see the "Example: Importing a Voice Gateway into ITM Multi-View" section.
Figure 1-1 Importing Devices to ITM
ITM performs the following tasks after a user imports a device:
•
•
•
Note
RME Synchronization is available only if you have downloaded and installed Incremental Device Update (IDU) 2 or later from the ITM download site: http://www.cisco.com/pcgi-bin/tablebuild.pl/item-3des.
Example: Importing a Voice Gateway into ITM Multi-View
Figure 1-2 shows that when a user imports a voice gateway, ITM Multi-View moves it to the default partition, P0. Only after a Partition Administrator assigns the voice gateway to an active partition, P1, does ITM Multi-View discover the gateway, assign it to system-defined groups, and prepare to poll the voice gateway.
Figure 1-2 Importing Devices to ITM Multi-View
What Is a Partition?
As you work with ITM, use the online help, or read the documentation, you will encounter the term partition. A partition is a logical grouping of a set of managed devices. These devices can belong to only one partition at any time. A partition also has a set of users who can perform operations on the devices in the partition.
If you are using ITM Multi-View, each device that ITM manages must be assigned to one of ten partitions. Users must also be assigned to one or more defined partitions, and can only view and act upon devices in one partition at a time.
If you are using ITM, all of your devices are in one partition and all users are assigned to that single partition.
Is ITM Ready to Use?
The person or team that installed ITM should have completed the initial configuration before you start working with ITM. The instructions for configuring ITM are included in Installation and Configuration Guide for IP Telephony Monitor. The following table lists the tasks that should already be complete before you start to work with ITM.
Step 1
Create at least one user in the Partition Administrator role

1 Alternatively, a Partition Administrator can import devices before creating a partition. See the "Tasks that a Partition Administrator Can Perform in Partition 0" section.
2 Only users who want to integrate ITM with a network management system (NMS) or trap daemon on another server must perform this task.
After the tasks in the previous table are complete, ITM is ready to monitor and analyze events, and provide notification of alerts on the Alerts and Activities display. ITM uses the default polling parameters and threshold values, default rediscovery and purging schedules, and default views. You should determine whether the default values are adequate for your use.
Table 1-2 lists tasks that you may attend to, at your discretion, after the initial configuration. The table lists optional configuration tasks and some day-to-day tasks that you may want to address when you first start to use ITM.
Table 1-2 Tasks to Consider when Initially Setting Up ITM
Subscribe users to receive e-mail notification of alerts and subscribe hosts to receive ITM-generated SNMP traps.
ITM displays the operational health of the IP telephony environment and IP fabric on the Alerts and Activities display. In addition, you can subscribe users and hosts to receive e-mail or ITM-generated SNMP traps, respectively, in response to alerts.
Update polling parameters and threshold values.
ITM provides default values. However, you can update the values based on your experience with and knowledge of the IP telephony environment and IP fabric. You should plan to apply the changes during a time of low activity on the network.
Set up confidence tests to monitor IP telephony application health.
You can configure various tests to run at intervals against IP telephony elements, such as Cisco CallManagers.
Import phones and configure phone monitoring.1
ITM monitors key phones.
Set up phone reachability tests to check the availability of key phones.2
You can configure ITM to test the availability of key phones in your network.
Set up Survivable Remote Site Telephony (SRST) tests.2
After you import devices to ITM, import a list identifying the source routers and target SRST routers in ITM inventory. This enables ITM to perform regular tests and to notify you when a branch office fails over to SRST.
Update device rediscovery schedules.
ITM provides a single default schedule for device rediscovery. You can use that schedule or suspend it and create additional rediscovery schedules.
Update phone discovery schedules.2
ITM provides six default schedules for phone discovery. You can update or delete them; you can also add phone discovery schedules (up to a maximum of ten.)
Set up RME Synchronization.2
You can automatically synchronize ITM inventory with RME inventory.
Add Alerts and Activities views.
Alerts and Activities views control which groups of devices are the focus of the Alerts and Activities display. ITM provides two default views. You can add more views.
Update the daily purging schedule.
By default, ITM purges the database at midnight. You can modify the schedule.
1 Phone Monitoring is available only if you have not downloaded and installed Incremental Device Update (IDU) 2 or later from the ITM download site: http://www.cisco.com/pcgi-bin/tablebuild.pl/item-3des.
2 Phone reachability tests, SRST tests, RME synchronization, and phone discovery schedules are supported only if you have downloaded and installed IDU 2 or later.
How Will I Use ITM for Day-to-Day Operations?
These topics briefly describe ITM functions that will be used frequently. On a day-to-day basis, operations personnel are likely to use the Alerts and Activities display and Fault History to monitor the IP telephony environment. Operations personnel are also likely to use IP Phone Information Facility to find phones.
Note
Network administrators and operators might similarly use the Alerts and Activities display and Fault History to assess network health. They might also use one of the following:
•
•
Note
In addition, network administrators and operators will use:
•
•
To make the most effective use of ITM on a day-to-day basis, network administrators and operators also need to understand the impact of operations on configuration and administration tasks. An overview is provided in the "Performing Scheduling Tasks" section.
The ITM functions that support day-to-day operations are further described in the following topics:
•
•
•
•
What Is Alerts and Activities?
The Alerts and Activities display provides a consolidated real-time view of the operational status of your IP telephony environment and IP fabric. When a fault occurs in your network, the IP Telephony Monitor generates an event (or events). Events are rolled up into alerts, one alert for each device with a fault.
When an alert occurs on an element in your active view (a logical group of devices), it is displayed on your Alerts and Activities display. You, or a user with administrative privileges, can customize your view to include only those device groups that are important to you.
From the Alerts and Activities display you can also:
•
•
•
•
You can see which components of the device are in the ITM manageable inventory as follows: After you locate the device on the Alerts and Activities display, you can click it and open a Detailed Device View. The Detailed Device View displays the manageable components of the device. From the Detailed Device View, a user in a Network Administrator role can suspend monitoring of a device component and, afterwards, resume monitoring of the device component again.
What Is Device Management?
Device Management involves keeping the inventory of devices that ITM monitors up-to-date. The following scenario describes the process for managing devices:
1.
2.
3.
4.
What Is Notification Services?
In addition to watching network conditions as they change on the Alerts and Activities display, you can use notification services to automatically notify users and other systems when specific changes occur on selected devices. To do so, you create subscriptions for either e-mail notification or ITM-generated SNMP trap notification. Subscriptions comprise:
•
•
•
You can add, modify, and delete subscriptions at any time as your need to disseminate the status and severity of alarms changes.
What Is Fault History?
Fault History provides the history of ITM events and alerts. The stored history includes alert information and annotations (informational text entered by ITM users), and event information and properties (component name and MIB attributes).
You can start Fault History in the following ways:
•
•
You can use Fault History to generate customized tabular displays of specific alerts, specific events, event dates, and event severity.
What Is IP Phone Information Facility?
Note
IP Phone Information Facility helps you to find phones and display pertinent details about them. IP Phone Information Facility includes:
•
–
–
•
–
–

Note
What Is Phone Monitoring Admin?
Note
With phone monitoring, you can monitor the health of important phones in your network. Through the Alerts and Activities display, you can view information about the phones, such as a phone's reachability and its registration with a Cisco CallManager. ITM supports up to 1,000 monitored phones.
How Does ITM Work?
These topics provide a simplified view of ITM user tasks and ITM processing:
•
•
•
Users Perform Device Management and Configuration
Users supply the information that tells ITM what to monitor. Figure 1-3 shows a user importing devices and phones, and performing optional configuration tasks to optimize ITM.
Figure 1-3 The Role of User Input
Users supply the following information:

ITM Performs Ongoing Monitoring, Analysis, and Notification
ITM continuously gathers information from devices and device components, analyzing and prioritizing events, and raising alerts.
Figure 1-4 ITM Continuously Monitors the IP Fabric
ITM generates alerts based on the following activities:
•
•

Users Respond to Notifications and Alerts
Most users will monitor the condition of the IP telephony system by using the Alerts and Activities display; others will respond to e-mail. External hosts will receive generated SNMP traps. Figure 1-5 shows how you can respond using Alerts and Activities.
