Drilldowns

Each drilldown page contains displays that provide you with specific information about the components of your system. Drilldowns mainly use two different types of displays — tables and charts. Drilldowns have the following features:

•
They can be configured to show all or some of the metrics associated with components.
•
You can access further information about displays in drilldowns by moving the mouse over the displays, or by clicking or right-clicking on them.
•
You can copy the data shown in drilldowns to other applications or save it to a file.
•
You can view a brief description of a drilldown by hovering your mouse over a component, such as a button, dataflow, status ball, or Toolbar button.
To view a drilldown

Right-click a component in a panel and select Show Details.

DNS Servers
•
DNS Servers - Shows information about the DNS servers in use by this Exchange 2007 server. The Exchange 2007 server uses the DNS server that is configured in the IP properties of the network adapter to locate domain controllers and global catalog servers, other Exchange servers, and remote domains.
DNS lookup settings can be specified on the Hub Transport server, which override the settings on the network adapter to route messages.

•
IMAP4 — shows the number of IMAP4 connections to this Exchange 2007 server. The Client Access role provides IMAP4 access to mailbox data for clients that rely on this protocol.

Information Store
•
Average Message Delivery Time — indicates the average time in seconds between the submission of a message to the mailbox store and the delivery to all local recipients (recipients on the same server) for the last 10 messages.
•
Total Logons — indicates the number of clients (including system processes) currently logged to any storage group in the information store.
•
Clients with RPC Latency > 2 sec – indicates the number of client reported RPCs (Remote Procedure Calls) with a latency greater than two seconds.
•
Average Client RPC Latency — shows the average time (in milliseconds) that it takes the server to respond to RPC connected clients.
•
Outlook Anywhere - indicates the number of unique users currently connected to this Exchange 2007 server via RPC/HTTP.

•
Virtual Memory — indicates current memory allocated to this process that cannot be shared with other processes.

Metrics

A metric is an individual piece of information that UC Diagnostics has collected about the performance of a system, such as perfmon counters. The information may be a numeric value (a number or percentage), a string of text, or some other piece of data.

To view the perfmon counters
•
Right-click a component and select Metrics.

The perfmon counter is visible in the Metric help section in the General tab.

Every time that the UC Diagnostics window is refreshed, UC Diagnostics retrieves the latest value of the metric, which can then be displayed in a drilldown or on the home page.

The Metric editor allows you to view and edit the properties of UC Diagnostics metrics, including their thresholds and severities. You can open the Metric editor for a component or a drilldown by right-clicking on the component and choosing Metrics from the invoked shortcut menu.

When you open the Metric editor, the General tab is open by default. Several metrics contain data source descriptions for the metric. The data source descriptions use the following list of functions.

 
Table 11. Exchange 2007 metrics.

Introducing the Exchange 2010 Diagnostic Console

The Exchange 2010 Diagnostic Console provides a real-time representation of the messaging system processes and components within specific connected Exchange 2010 servers. You can diagnose and resolve issues using the Exchange 2010 Diagnostic Console.

The Exchange 2010 Diagnostic Console contains the following:

•
Home pages that highlight targeted areas of the Exchange 2010 server activity.
•
Graphical flows that illustrate the rate at which data is moving between server components. Colorful buttons, gauges, queues, spinners, and containers display the value of key statistics and metrics.
•
Visual warnings if the performance metrics exceed acceptable thresholds, which you can adjust. The buttons, gauges, queues, and other visual objects, collectively referred to as components, change color to show you the source of the problem.
•
Warning messages that are displayed well before the traffic levels of a server become critical.
•
A range of reports and graphs that provide you with detailed information about a server. You can view this information on the screen or you can print it.
