AppSpeed Overview 1
VMware vCenter AppSpeed provides performance management and service-level reporting for services
running within virtual appliances. AppSpeed analyzes the traffic that flows between users, Web applications,
and back-end servers. This analysis provides visibility into multitier services. The analysis enables you to
rapidly identify performance problems that originate from inadequate resource allocation and service
problems.
AppSpeed probes capture ingoing and outgoing traffic servers that are running on hosts on which the probes
are deployed. This feature enables AppSpeed to monitor the real-time user experience for all transaction
requests, analyzing performance through all layers.
AppSpeed establishes baselines based on service behavior over time and compares real-time metrics to service-
level targets. In addition, AppSpeed maintains historical monitoring data that you can use to analyze trends
and for troubleshooting purposes. You can identify which component is responsible for a performance problem
and identify the likely solution. You can also configure AppSpeed to generate real-time events in response to
transaction-level performance and availability problems. Optionally, you can send email notifications when
events are generated.
AppSpeed includes a wide range of predefined viewing options to facilitate the analysis of performance data.
The predefined views incorporate different combinations of data, presented in tabular and graphical format.
Different sets of views are available when you select a server object, a service object, or a transaction object.
This chapter includes the following topics:

n“AppSpeed User Interface Overview,” on page 8
n“Navigating the AppSpeed Interface,” on page 8
Access the AppSpeed User Interface
You access AppSpeed from the VMware vSphere Client.
Prerequisites
Verify that the AppSpeed plug-in is enabled in the Plug-ins menu.
Procedure
1 In the VMware vSphere Client, click an object in the Inventory tree.
If an AppSpeed probe is deployed on the object, a new Services tab is added to the user interface.
2 Click the Services tab.
Data related to services that AppSpeed detects for the selected vSphere object appears.
VMware, Inc. 7

3 (Optional) In the Open AppSpeed in list, select either Browser or vSphere Client and click Go, to open
the AppSpeed user interface.
4 (Optional) In the VMware vSphere Client, click Home and in the Solutions and Applications area, click
the <AppSpeed_namespace> icon.
If you have more than one AppSpeed Server, a namespace will appear for each instance.
The AppSpeed user interface opens. By default, the AppSpeed Overview portal appears.
If you access AppSpeed by clicking an object in the vSphere Client inventory, the displayed data relates to the
selected object. If you access AppSpeed from the Solutions and Applications interface, the displayed data
relates to all the data on the selected AppSpeed Server.
What to do next
If you are accessing the AppSpeed user interface for the first time, you must install probes. See “Deploy an
AppSpeed Probe,” on page 30.
AppSpeed User Interface Overview
The AppSpeed user interface is categorized into modules. You access the modules by clicking their name on
the AppSpeed menu bar. You use different modules to perform different tasks.
Overview Portal Displays a series of portlets where you can quickly analyse the state of
AppSpeed Server. Each portlet contains one or more links that provide more
detail about an item.
Inventory Provides a list of servers or services that are running on AppSpeed Server. The
displayed data includes the state of each object, its throughput, number of hits
per second, and latency, communication protocol and creation time.
Mapping Provides a list of unmapped servers or services and data related to their latency,
hits, and throughput. From this module, you can manage your servers,
services, and deleted objects. You can also add or update SSL keys and define
SSL endpoints.
SLA & Events Displays the events log of the changes in states that deviate from the Service
Level Agreement. You can export the log as a CSV file and configure email
notification settings. See “View the Events List,” on page 44 and “Configure
AppSpeed Email Notifications,” on page 43. You can also access the Service
Thresholds data.
Administration Provides administrative functions, including deploying probes, and creating
and viewing support information. See Chapter 4, “AppSpeed
Administration,” on page 29.
Navigating the AppSpeed Interface
Using the AppSpeed navigation aids, you can access increasingly detailed levels of information about an object.
You can also move back and forth between pages, with the pages retaining the content they last had when you
navigated away from them.
Key Navigation Points
When you click on a module on the AppSpeed menu bar, a page on the page selection bar, or a link in a table,
breadcrumbs appear immediately under the AppSpeed menu bar to help you orient yourself in the application.
Breadcrumbs indicate your current location, relative to the AppSpeed application.
VMware vCenter AppSpeed User’s Guide
8 VMware, Inc.

You can click a breadcrumb to immediately jump to that page.
NOTE Breadcrumbs indicate your current location relative to the AppSpeed application, not necessarily the
way you navigated to that location.
If you click a link, other than a title in a menu bar or a breadcrumb, the specific target page of that link appears.
For example, if you click a service link in a portlet, the services page in the Inventory module appears.
Navigation History
When you use the Back and Forward buttons to move between pages, the settings of the page that you move
from are retained. For example, assume that you are looking at the Analysis view of a service and have selected
the Latency Breakdown tab. You move to the Events page in the SLA & Events module, then return to the
Analysis view of the service, using the Back button. The Latency Breakdown tab appears again.
The history of data that you select from drop-down menus is not retained. For example, if you change the time
frame when viewing data in the Latency Breakdown tab, that time frame is also applied to the page that appears
when you click the Back button.
Search Navigation
When you use the Search field to search, you can use the Back and Forward buttons to move between your
search results.

Summary View
The Summary view is the default view when you select a service or server in the Inventory module. The portlets
that appear depend on whether you select a service or a server.
Summary View Portlets for Services
These portlets are available when you are viewing the summary for a service.
Latency Trends Graphs data related to latency of the selected service, including the total length
of time the service exceeded its SLA during the specified time frame.
See More shows latency over time.
Latency Breakdown Graphs latency data, broken down by server, network, and retransmissions. If
the service is an Oracle database, Client Fetch is included in the breakdown.
The portlet also includes the average latency time and standard deviation
during the selected time frame.
See More shows more service latency breakdowns.
Usage Graphs data related to the average hit rate in comparison to the average
throughput.
See More links to usage over time.
Database/Domains Lists the domains or databases on which the service is running, depending on
the type of service that is selected.
Servers Lists the servers on which the service is running, and the latency state of the
service.
Dependencies A list of services that are dependent on the selected service, and the services
on which the selected service is dependent.
Summary View Portlets for Servers
These portlets are available when you are viewing the summary for a server. The portlets that appear depend
on whether the virtual machine is running inside or outside vCenter.
Latency per Service Graphs data related to latency of each service running on the selected server,
including its latency during the specified time frame.
See More links to services latency.
Usage Graphs data related to the average hit rate on the server, in comparison to the
average throughput.

Chapter 2 Viewing Performance Data
VMware, Inc. 13

Analysis View
The Analysis view provides graphical and tabular information for the selected service or server. You can select
views and timeframes to highlight the specific information to view. The Analysis view is available for service
and server objects.
Analysis data appears in graph and table forms. On the tabs on the graphical and tabular forms, you can define
the detail of the view.
Each table appears on a separate tab. A row appears at the bottom of every tab, showing summary data for
the selected object. The data summarizes the entire time frame that you select. This row does not change when
you navigate between tabs.
An eye icon displayed next to an object in a table indicates that the object is selected.
You can perform the following actions on the tabular display data.
nView data on the chart for specific services, servers, or transactions.
nView dependency data for the specific service or server.
nNavigate a specific service, server, or transaction to view additional data.
nSort data in the table and rearrange the order of the columns.
nSearch for specific services or servers.
nHighlight the data for a specific object on the corresponding graph by selecting its row in the table.
nExport the data to a CSV file.
When you select an Analysis view from the drop-down menu, the resulting data appears in default format in
the table and the graph. If you then click a tab in the graph pane, a new graph appears with data that is relevant
to the tab you clicked. The data in the table does not change, only that in the graph. You can compare the
different sets of data in the graph and the table, to analyze performance.
Performance View
You can use the Performance view to compare performance indicators of all services on a selected server, or
to analyze a specific server.
You can display key performance indicators for services and servers. For example, you might see that latency
is above SLA for a service. You want to analyze the performance of the individual servers on which this service
is running to detect the cause of the problem. By performing this analysis, you can see how components on a
selected server were performing.
When you double-click the service in the Overview portal or in the Inventory module, the Summary view for
the service appears.
When you select the Performance view, a graph displays KPI data for the server on which the service is running.
If the service is running on more than one server, option buttons appear for each server name. If you select a
different server, the data changes accordingly.
You can customize the view by adding or removing KPIs related to the scenario you are analyzing. You can
also hide KPI data on the graph by clicking the relevant KPI on the legend.
You can use the slider under the graph to focus on a specific time within your chosen time period.
VMware vCenter AppSpeed User’s Guide
14 VMware, Inc.

Thresholds View
In the Thresholds view, you can see the service level agreement (SLA) state of the service that you selected in
the Inventory. You can also enable and disable SLA monitoring and change the SLA threshold settings. The
thresholds that you specify affect when events are generated.
Thresholds are the service performance values that you specify that should not be exceeded if service level
agreements SLAs are to be met. You must have thresholds defined for an object before you can monitor its
performance.
By default, AppSpeed specifies threshold values. AppSpeed monitors performance of services and servers and
defines thresholds based on the monitored data. You can manually define thresholds. You can also change
thresholds that AppSpeed specifies or that you specify manually.
See “SLA Monitoring,” on page 40.
Events View
The Events view provides a list of instances when SLA states for a selected service or server changed from one
state to another.
After SLA thresholds are specified for a service, and SLA monitoring is enabled, deviations from the SLA
thresholds generate events. Events are listed in a table that is available in the Events view of the Inventory
module.
See “Viewing Events,” on page 44.
Define the Time Frame for Data Collection
You can select a predefined time frame, such as a day or week, or you can specify the start and end times and
dates for which performance data is displayed.
The specific units of time in which the data is displayed depend on the data time frame that you select.
The length of time that aggregated data is stored in the AppSpeed internal database depends on the selected
time period.
