A - E

Access control list (ACL)

A list that is created by using a PATROL Agent configuration variable and that restricts access to a PATROL Agent. ACLs are used to restrict access to objects in the Common Object System (COS) namespace.

Agent namespace

A memory array that contains an internal representation of the PATROL Agent object hierarchy. Values in the agent namespace are available to PATROL Script Language (PSL) scripts, eliminating the need to develop code to collect this data.

Agent query

A feature that constructs SQL-like statements for querying PATROL Agents. Agent Query produces a tabular report that contains information about requested objects and can be used to perform object management activities, such as disconnecting and reconnecting computers. Queries can be saved, reissued, added, or changed. 

Application check cycle

The interval at which application discovery occurs. The PATROL Agent process cache (as opposed to the system process table) is checked to ensure that all application instances and files previously discovered still exist in the cache.

Application class

The object class to which an application instance belongs. 

Application discovery

A PATROL Agent procedure carried out at preset intervals on each monitored computer to discover application instances. The application class includes rules for discovering processes and files by using simple process and file matching or PSL commands. Application definition information is checked against the information in the PATROL Agent process cache, which is periodically updated. Each time the PATROL Agent process cache is refreshed, application discovery is triggered.

Application state

The condition of an application class or an application instance. The most common application states are OK, warning, and alarm. An application class or instance icon can also show additional conditions.

Attribute

A characteristic that is assigned to an object  such as computer class, computer instance, application class, application instance, parameter, etc. that you can use to monitor and manage that object. Computers and applications can have attributes such as command type, parameter, menu command, InfoBox command, BMC PATROL setup command, state change action, or environment variable. Parameters can have attributes such as scheduling, command type, and thresholds. An attribute can be defined globally for all instances of a class or locally for a particular computer or application instance. An instance inherits attributes from a class; however, an attribute defined at the instance level overrides inherited attributes. 

Built-in command

An internal command that monitors and manages functions such as resetting the state of an object, refreshing parameters, and echoing text. The command is identified by the naming convention %command_name

Built-in macro variable

An internal variable that is used by the built-in commands and PATROL Script Language (PSL). The variable is identified by the naming convention variable_name. 

Class

The object classification where global attributes can be defined. The attributes are then inherited by instances of the class. An instance belongs to a computer class or an application class. 

Command type

Categorization of commands according to its manner of execution. This attribute must be defined for a parameter command, a parameter recovery action, a menu command, an InfoBox command, a configuration command, or a state change action. The PATROL Agent provides two command types: OS and PSL. PATROL Knowledge Modules (KMs) provide additional command types. The developer functionality of a PATROL console can be used to add or change command types.

Computer class

The basic object class to which computer instances of the same type belong. Examples include Solaris, OSF1, HP, and RS6000. There are computer classes for all supported computers and operating systems. A PATROL Console with developer functionality can add or change computer classes.

Computer instance

A computer instance contains the information and attributes of the computer class to which it belongs. 

Connection mode

The mode in which the PATROL Console is connected to the PATROL Agent. The mode can be developer or operator and is a property of the Add Host dialog box (in BMC PATROL 3.x and earlier), an Add Managed System wizard, or another connection method. The connection mode is a global (console-wide) property that can be overridden for a computer instance. 

Container

A custom object that you can create to hold any other objects that you select—such as computers, applications, and parameters—in a distributed environment. In Microsoft Windows, a container is referred to as a folder. You can drag and drop an object into and out of a container icon. However, you cannot drop objects from one computer into another computer. After a container is defined, the object hierarchy applies at each level of the container. That is, a container icon found within another container icon assumes the variable settings of the container in which it is displayed. 

Deactivate a parameter

Deactivating a parameter stops running a parameter for selected computer or application instances. In PATROL Consoles for Microsoft Windows environments, deactivating a parameter stops parameter commands and recovery actions. Deactivating a parameter also deletes the parameter icon from the application instance window without deleting the parameter definition in the KM tree. A deactivated parameter can be reactivated at any time.

Deactivate an application class

Deactivating an application class stops monitoring an application class and all of its instances on selected computer instances. In PATROL Consoles for Microsoft Windows environments, deactivating an application class deletes the application class and all of its instance icons from the computer window without deleting the application class or definition in the KM tree. A deactivated application class can be reactivated at any time. 

Deployable package

A deployable package consists of monitoring solution components that you can select and install together. These components are also called installation components. You can reuse deployable packages on a single or multiple computers.

Developer mode

An operational mode of the PATROL Console that can be used to monitor and manage computer instances and application instances. Developer mode can also be used to customize, create, and delete locally loaded Knowledge Modules (KMs) and commit these changes to selected PATROL Agent computers. 

Disable a KM

To temporarily or permanently block an application or Knowledge Module (KM) from loading, and to block the PATROL Agent from using that KM. When a KM is disabled (added to the disabled list) in the agent configuration file, the KM files are not deleted from the PATROL Agent computers. However, the PATROL Agent stops using the KM to collect parameter data and run recovery actions. By default, no KMs are disabled. Most KMs are composed of individual application files with a .km extension. 

Discovery

Scanning your infrastructure environment for configuration data.

Event

An event is a notification that indicates a change in the state of an application or device that you are monitoring. Thus, an event can represent an error or warning, it can mean the crossing of a set threshold, or it can mean everything is working as expected, and so on. Alarms are type of events that are generated when the user-specified threshold values are violated. PATROL events are events generated by the PATROL Agent.
