Unified Communications Diagnostics 8.6.2

Table 8. Exchange 2013 message flows panel.
Message Flow	Description
HTTP Proxy Requests/sec	Shows the rate of the HTTP Proxy requests per second.
Inbound Msgs/Sec	Shows the number of messages (sent inbound into the forest) received by the SMTP server each second.
Msgs Sent/sec	Shows the number of messages sent by the SMTP Send connector per second.
Msgs Received/sec	Shows the rate of messages received by SMTP Receive connector on this Exchange 2013 server. The SMTP Receive connector is part of the Microsoft Exchange Transport service on Exchange 2013 holding Mailbox server roles. It controls message processing through a series of SMTP Receive agents performing anti-spam, antivirus, and other tasks before messages are submitted to the categorizer.
Messages Sent/sec	Shows the rate of messages delivered to the mailbox database using Exchange Remote Procedure Call (RPC).
Messages Submitted/sec	Shows the rate of retrieving messages from Mailbox database using Exchange Remote Procedure Call (RPC).
Bytes Written/sec	Shows the Process IO Write Bytes / Sec on the CAS Server through MSExchangeFrontendTransport.
Bytes Read/sec	Shows the Process IO Read Bytes / Sec on the CAS Server through MSExchangeFrontendTransport.
Bytes Read/sec	Shows 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 read from the disk subsystem.
Bytes Written/sec	Shows 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 written to the disk subsystem.

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.

Associated Charts/Tabs

Active Directory Server

•

Active Directory Servers - shows information about the Active Directory servers in use by this Exchange 2013 server. Exchange 2013 stores all configuration and recipient information in the Active Directory directory service database.

•

DNS Servers

•

DNS Servers - Shows information about the Domain Name System (DNS) Servers used by this Exchange 2013 server. The Exchange 2013 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.

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 10. Exchange 2013 metrics.
Function	Description
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
