Using the Real-Time Dashboard
The Real-Time Dashboard provides an overall picture of voice network health. The Summary View displays managed voice device groups and the number of devices in the groups with faults in each fault category. Starting from the Summary View, you can open more detailed views:
•Status View—Displays the status of managed devices in the selected voice device group. From this view you can open a more detailed view of a particular device, called the Device Detail View.
•Device Detail View—Displays relevant details for a particular managed device.
Note Unmanaged devices do not appear in the Real-Time Dashboard.
Both the Summary View and the Status View use System Status indicators to display VHM system health. The status indicator is green if all the processes in the VHM system are communicating with each other correctly. The status indicator is red if one or more processes in the VHM system lose contact with the ESS Bus (CMF Event bus) or the VHM server. When you move the mouse over the System Status indicator, system status information is displayed as a tooltip.
The DFM System Status Indicator shows the DFM server's connectivity with VHM backend processes.
While you are browsing the status of voice devices on the Real-Time Dashboard, you can quickly open an Administration Console (if you have administrative privileges), a Monitoring Console, or other Cisco applications, to provide:
•More data, such as alarms that have been logged—for example, you can view alarms on the Monitoring Console.
•The ability to take an action based on what you have already seen—for example, you can send email about an alarm from the Monitoring Console.
See the "Starting Additional Consoles and Views from the Summary View" section and the "Starting Additional Consoles and Views from the Status View" section for more information.
Managing Data in the Real-Time Dashboard
To help you organize and search the information in the views that the Real-Time Dashboard offers, you can sort the information in any order. You can also use the Find capability to look for a particular device group or device.

Reachability
|
Reflects whether or not DFM can reach the device. If DFM can reach the device, it checks the status of the SNMP agent on the device. If DFM can reach the agent, then the device is considered reachable. Reachability includes both IP and SNMP connectivity.
Note When DFM and VHM run on separate machines, VHM may display a device that DFM cannot reach even when VHM can reach the device.
|
Environment
|
Reflects device parameters. The following environment parameters are monitored:
•Power Supply
•Fan Status
•Chassis Operating Temperature
•Battery State
•Temperature Sensor Status
Note Depending on the system class that the device belongs to, these parameters may vary.

Starting Additional Consoles and Views from the Status View
You can open the Administration Console, the Monitoring Console, and Inventory Collection Scheduling from either the Summary View or the Status View using the same methods described in the "Starting Additional Consoles and Views from the Summary View" section.
The Status View additionally provides a starting point for applications that can provide more details for a specific device:
•Real-Time Dashboard-Device Detail View—Opens a detailed view of the device. See the "Using the Device Detail View" section for more information.
•Display CiscoView—Starts the CiscoView application for the selected device.
•Expand/Collapse ICS 7750—Applies only to the ICS 7750 device. If an ICS 7750 device is not detected, this button is dimmed. You can also expand or collapse an ICS 7750 by right-clicking a device and selecting either Expand (which displays the ICS 7750 device) or Collapse (which displays the ICS 7750 logical device only).
•CallManager Administration—Applies only to devices running the CallManager. Opens the CallManager Administration pages.
•Workflow Administration—Applies only to devices running a workflow application. Opens the Workflow Application Admin pages.
Note CiscoView, CallManager, and Workflow applications are additional products that are not provided with VHM. These products can be started from the Status View if they are already available.
To start an application for a particular device from the Status View:
Step 1 Click a device to select it.
Step 2 Perform one of the following steps:
•Click the button for the application you want to start.
•Select the application from the Tools menu.
•Right-click the device and select the application from the context-sensitive menu that is displayed as a result.
Using the Device Detail View
For each device listed in the Status View, you can start a Device Detail View. The Device Detail View window provides the status reported for the device, as well as general device information. The status values in the Device Detail View window are updated only when you click the Refresh button.
To display the Device Detail View for a device:
Step 1 Perform one of the following steps:
•Double click on the device in the Status View window.
•Right-click a device on the Status View window and select the Device Detail View option.
•Select a device on the Status View window and click the Display Device Detail View button.
•Select Tools > Real Time Dashboard-Device Detail View.
Note The Device Detail View is not real time; use the Refresh button to update the current device status.
The Device Detail View window displays one tab with status information for each applicable category for the device:
•Environment
•System
•Interface
•Application
•Device Information
The number of categories varies with each device. For example, for the ICS 7750, the Device Detail View window contains only two tabs: Environment and Device Information. Other than the power supply, the ICS 7750 device has no system level entities or interfaces and applications; therefore, other tabs are not displayed for this particular device.
Using the Monitoring Console
From the Monitoring Console, you can view alarm logs, obtain more information about alarms and the conditions that may be causing them, and take action in response to alarms. Some examples of voice-specific alarms that may appear in the alarm logs are:
•Voice application problems such as voice applications failing or not responding.
•Gateways losing connectivity with CallManager.
•Virtual memory usage on a media server reaching high levels.
Starting the Monitoring Console
To start a Monitoring Console:
Step 1 Use one of the following procedures:
•From the Voice Health Monitor drawer, select Monitoring Console.
This opens a Monitoring Console that by default:
–Displays two alarm logs: one with VHM alarms only and one with VHM and DFM alarms combined
–Does not display an Inventory Browser
•From any running Administration or Monitoring Console, select File > New > Monitoring Console. This opens a Monitoring Console that displays a single alarm log that includes both VHM and DFM alarms.
•From any Summary View or Status View in the Real-Time Dashboard, select Tools > Voice Fault Monitoring Console. This opens a Monitoring Console that displays a single alarm log that includes both VHM and DFM alarms.
When presented with an alarm log that includes both VHM and DFM alarms, you can identify the server that generated the alarm by examining the domain manager column. The domain manager will be either VHM or DFM.
Note When you open a Monitoring Console using the toolbar button, the console includes an Inventory Browser display. If you open a Monitoring Console by selecting Voice Health Monitor > Monitoring Console, the console does not display the Inventory Browser.
The following related topics are described in the Device Fault Manager User Guide:
•Customizing and saving a console for later use
•Opening a remote console; that is, a console that was saved on another VHM server host
Note For descriptions of all menu options and toolbar buttons in the Monitoring Console, refer to the Device Fault Manager User Guide.
The Monitoring Console gives users the ability to specify which notifications they want to receive on the alarm log display and to further filter those alarms interactively as they view them. See the "Managing Events in the Monitoring Console" section for more information.
Displaying Alarm Notifications
VHM generates notifications for two kinds of events:
•Symptoms—Indicate fault conditions.
•Compounds—Indicate one or more symptomatic events associated with a managed object.
Events are correlated to symptoms for analysis. Notifications are displayed in an Alarm Log whenever events occur, and on the Events Tab of the property sheet for the object where the event occurs. Table 2-6 lists the types of notifications and how they are color-coded in the Alarm Log.

Managing Events in the Monitoring Console
To use the Monitoring Console most effectively, you must be able to perform the following tasks:
•Apply filters to the alarm log—A user can further refine the list of displayed events by applying alarm log filters while viewing an alarm log.
•Take actions based on an alarm—A user can send email or a page or start a script for a particular alarm.
Instructions for setting up the system to perform these tasks, and instructions for the tasks themselves, are provided in the Device Fault Manager User Guide.
Changing Your Subscription Profile
A subscription profile is a saved list of events that have been subscribed to for notification. The events you subscribe to determine the notifications that are displayed in the Monitoring Console. By editing a profile, you can change the notifications that are reported. All users automatically subscribe to the default profile, which subscribes to all types of events (symptoms and compounds). If a user edits the profile, the profile is named according to the user's login and saved in the VHM repository (when you save the inventory). If a user has edited the profile, it is applied whenever the user opens a console.
Caution Be careful when modifying a subscription profile, because changes can have a major effect on what is displayed by your consoles.
Note You can also directly edit the VHM adapter configuration files to either use an existing subscription profile or establish specific classes, instances, and events you want the adapters to track. This information is provided in the Device Fault Manager User Guide.
You can subscribe to (and unsubscribe from) the events you want to be notified of by changing your individual subscription profile, as described in the Device Fault Manager User Guide.
Configuring the Monitoring Console to Remove Cleared Events
To configure the Monitoring Console to automatically remove events on unmanaged devices, you must create a filter.
To create a filter to automatically remove cleared events:
Step 1 Start the Monitoring Console. See the "Starting the Monitoring Console" section.
Step 2 Select an event from the VHM pane of the Monitoring Console.
Step 3 Select Log from the menu bar.
Step 4 Select Filter from the drop-down menu.
The Alarm Filter Criteria dialog box opens.
Step 5 In the dialog box, under the General tab, select the Automatically remove cleared events check box.
Step 6 Click OK.
