Glossary
This topic defines terms commonly used in the BMC TrueSight App Visibility Manager documentation.
availability
In BMC Real End User Experience Monitoring and Analytics, the ability of an application to provide resources as intended.
BMC Application Diagnostics
BMC Application Diagnostics Collector
In the BMC Application Diagnostics product, services one or more Application Diagnostics Agents. Data captured by the Application Diagnostics Agents, along with metrics data for the application server and host computer, is sent to the Application Diagnostics Collector and stored in a MySQL database. Each Application Diagnostics Collector can handle up to 200 Application Diagnostics Agents.

BMC Application Diagnostics Server
BMC Application Management Suite
The BMC Application Management Suite supports the expanding requirements of application owners, line-of-business stakeholders, release managers, and IT operations. The product suite includes solutions that support Application Release Automation for faster releases with fewer errors at the lowest cost and Application Performance Management that monitors end-user experience and application performance to proactively maintain service levels and customer satisfaction. For more information, see Application Management.
BMC Application Management Console component
The main user interface of BMC Real End User Experience Monitoring, BMC Application Diagnostics, and BMC Synthetic End User Experience Management. This is a virtual machine that hosts dashboards and system-management features. It also provides links to the user interfaces of the Real User Analyzer and Real User Collector components.
BMC Real End User Experience Monitoring and Analytics
BMC Synthetic End User Experience Monitoring
The BMC Synthetic End User Experience Monitoring product monitors the performance and reliability of worldwide applications. Synthetic (also called robotic) transactions measure site health based on end-user-experience metrics such as availability, accuracy, and performance. The product determines the health of business applications and measures their response time by running recorded transactions at key locations throughout the enterprise or on the internet. Response time is the time required to complete a transaction from the end user’s point of view. Response time is a key measurement of many customer service level agreements (SLAs).
The product is available through MarketZone distribution, under the Borland Silk Performer Synthetic Transaction Monitoring for BMC Software licensed product, and comprises the following components:
- BMC Application Management Console
- Real User Monitor (a supporting core component for the monitoring system)
- BMC Synthetic Transaction Execution Adapter Agent
- Borland Silk Performer Synthetic Transaction Monitoring for BMC Software
BMC TrueSight Operations Management
BMC TrueSight Operations Management learns and baselines the behavior of your applications and IT infrastructure; collects and processes events from a wide variety of sources; predicts problems before they occur; automatically pinpoints probable-cause across technology silos; and initiates standardized problem triage and resolution processes. The BMC TrueSight Operations Management Suite optimizes application performance by reducing the number of outages, speeding mean time to repair, and improving operational efficiency through out-of-the-box automation and integration. For more information, see IT Operations Management.
capture rate
In BMC Real End User Experience Monitoring and Analytics, the average rate of HTTP hits observed on the wire.
cross-domain policy
In BMC Real End User Experience Monitoring and Analytics, a set of rules for enabling and disabling the cross-domain data loading.
cross-domain policy file
In BMC Real End User Experience Monitoring and Analytics, an XML file that describes the configuration of the cross-domain policy.
entry point file
In the BMC Application Diagnostics product, an editable text file that enables you to configure group and name entry points, such as URLs into a more logical and readable form.
Geo PCL
In BMC Real End User Experience Monitoring and Analytics, the Geographic Performance Compliance Level is a configurable criteria used by the system to characterize the end user's experience of server or application performance in a given region.
hit
In BMC Real End User Experience Monitoring and Analytics, a hit consists of the HTTP request and response pair.
latency
In BMC Real End User Experience Monitoring and Analytics, the time it takes the server to process the object or page, in milliseconds
network latency
In BMC Real End User Experience Monitoring, the time it takes the network to transmit the object or page, in milliseconds.
object detection
In BMC Real End User Experience Monitoring, the basic unit of web-application content; can be a container (for example, index.html), a component (for example, image.gif, style.css), or a stand-alone object (for example, document.pdf, file.zip).
PCL
Performance Analytics Engine component
A BMC Real End User Experience Monitoring component that enables you to store traffic data in a central, off-board storage location. Its Performance Analysis user interface enables you to locate the root cause of problems by sorting and filtering data in an intuitive and efficient way (by "zooming in" on categories of most relevance).
policy file
In BMC Capacity Optimization, a text file containing specifications for alerts, alert conditions, and alarm actions to investigate computers and domains. For Investigate policy files, use the .plc file extension to easily identify policy files.
In BMC Application Diagnostics, an editable text file that enables you to define (configure) how the BMC Application Diagnostics Agents and BMC Application Diagnostics Collectors behave and operate.
Real User Analyzer component
An integral part of the BMC Real End User Experience Monitoring that retrieves data from one or more Real User Collector devices.
Real User Collector component
Captures traffic data from a tapping point between the application and the end user (for example, a network tap or a mirror port on a network switch) and makes it available to a Real User Analyzer component.
An integral part of the BMC Real End User Experience Monitoring; a device that captures traffic passing between your web applications and end users.
Real User Monitor component
Combines the Analyzer and Collector components on the same virtual machine.
Real User Application Visibility Connector
A module that provides the interfaces and integration logic to connect monitored user sessions to business-transaction diagnostics.
recording configuration file
In BMC Application Diagnostics, a file that defines what should be monitored with regards to the different Java and .NET technologies in the monitored applications. Do not edit this file without authorization from BMC Customer Support.
reference list
The list of the most popular or recently observed values for a given attribute of traffic in the system.
session detection
An identifiable period of interaction between an end user and an application. (update)
sessionization
The process of traffic segmentation based on user-defined rules.
session data space
The amount of disk space reserved for storing session data.
Page Service Level Threshold (SLT)
A rule that is being set up in the system to determine whether a page was delivered to end users within an acceptable time.
traffic capture
Recording of the data packets sent by the web to the end user. (update; plunk from End-user-experience-traffic-data-capture-and-segmentation)
Watchpoint
A configurable segment of traffic selected because it is of particular interest for monitoring purposes. Page Watchpoints are used to monitor only traffic for certain pages, and with object Watchpoints, you monitor traffic for certain objects.
web beacon
An object that is embedded in a web page and is usually invisible to the end user but allows monitoring the behavior of this user. (update)
