OS/Subsystem Panel

The Subsystem panel displays components that represent the health of important subsystem features. This information includes:

Exchange Services

Indicates the sum of CPU utilization for all of the Exchange 2010 services running on this server.

System Disk

Shows the percentage of disk usage for the Windows system disk on this Exchange 2010 server.

CPU Usage

Shows the amount of CPU used on this Exchange 2010 server.

System Memory

Shows the amount of physical memory (RAM) Windows is using. Physical memory usage can normally remain close to the total amount of physical memory installed on the system unless the amount of physical memory exceeds the amount of virtual memory that Windows is using. Windows normally keeps some physical memory available for immediate use.

Ping Time

Indicates the amount of time it takes the computer running the Diagnostic Console to ping the target server.

Top CPU Consumer

Identifies the process that is consuming the most CPU on this Exchange 2010 server.

Top Memory Consumer

Identifies the process that is consuming the most memory on this Exchange 2010 server.

Message Flows

The Exchange 2010 Diagnostic Console contains the following message flows that show the amount of information being sent to various components in your Exchange 2010 environment.

Msgs Submitted/sec

Indicates the rate of messages being submitted per second to this Exchange 2010 transport queues.

Msgs Received/sec

Indicates the rate of messages received by SMTP Receive connector on this Exchange 2010 server.

MAPI Msgs Submitted/sec

Indicates the rate that messages are submitted to the Information Store on the Exchange server by MAPI clients (connected with Outlook).

OWA Msgs Received/sec

Indicates the rate that bytes are received by Exchange server from OWA clients.

ActiveSync Bytes Received/sec

Indicates the rate that bytes are received by Exchange this server from ActiveSync mobile devices.

Indicates the number of bytes per second received from POP3 and IMAP4 clients.

Msgs Sent/sec

Indicates the number of messages sent per second to the transport.

Msgs Delivered/sec

Indicates the rate of messages delivered to all recipients with mailboxes on this Exchange 2010 server.

Indicates the number of bytes received per second from all RPC clients on this Exchange 2010 server information store. RPC clients includes all internal Exchange system components.

Bytes Sent/sec

Indicates the number of bytes sent per second to all RPC clients from this Exchange 2010 server information store. RPC clients includes all internal Exchange system component.

Bytes Read/sec

Indicates the rate at which data is being read from the disk, network, and device subsystems of the Windows server running Exchange. The data is primarily being read from the disk subsystem.

Bytes Written/sec

Indicates the rate at which data is being written to the disk, network, and device subsystems of the Windows server running Exchange. The data is primarily being written to the disk subsystem.

Msgs Queued/sec

Indicates the number of messages queued for delivery per second on this Exchange 2010 server.

Msgs Sent/sec

Indicates the number of outbound messages sent per second by the SMTP send connectors on this transport server.

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:

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

Active Directory Servers

DNS Servers

Transport In/Transport/Transport Out

Clients

Information Store

Exchange Mailbox Databases

Exchange Services

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.

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.

max(x)

the maximum of a set of values in list x

max(x,y)

the maximum of x and y

min(x)

the minimum of a set of values in list x

count(x)

the number of values in list x

sum(x)

the sum of a set of values in list x

if(x,y,z)

if x is true, then return y, otherwise, return z

snull(x)

if x could not be collected, then return true

avg(x)

the average of values in list x
