List of Glossary terms




A lighter installation of Analytics on a server that sends data from that server back to the Analytics Hub for processing. Can be installed on any server on your network including the Hub server.

Analytics Endpoint

Configured endpoint that can be used with Analytics-enabled applications to send client data to Analytics.


(Application Programming Interface) An interface to an application which allows other applications to communicate with it. See also. REST API.

ArcGIS Server

Software that makes it possible to create GIS services over the web for web mapping applications.

Average Disk I/O

Disk I/O refers to the throughput of operations on a physical disk. The key measurement is latency, which is the time required for a computer to process a data request from the processor and then retrieve that data from the storage device.


Log in credentials used to authenticate whether a user has permission to log in to a site or server.

Authentication type

The method used to authenticate a user to check that they have permission to log in to a site or server, for example, Windows Authentication, OAuth2, Token. In some cases, organizations use double-layered security where a user has to log in twice using different authentication types.


An item that is dependent on a particular resource. For example, a web map is dependent on the service that it references to work correctly.


The amount of time that a server or other resource has not been available for use for any reason, including maintenance or problems.


See REST Endpoint and See Analytics Endpoint.


A network security system that controls incoming and outgoing network traffic.

Geocoding service

An ArcGIS service that converts spatial data to actual addresses and back again. Geocoding services are also known as address locators or geocoders.

Geometry services

An ArcGIS service that performs geometric calculations such as buffering, projection, and measurement.

Geoprocessing service

An ArcGIS service used for geoprocessing operations. Geoprocessing refers to a set of tools for processing geographic data. The geoprocessing tools are used to perform spatial analysis or manage GIS data, for example, append, buffer, dissolve, intersect, union, or clip.

GP service

See Geoprocessing service.


(Geographic Information System). A system that captures, analyzes, or manages data that is linked to a location on a map.

Host Name

A human-readable name that stands for an IP address. For example, and are host names.

Image service

An ArcGIS service that supplies image services. The services include raster and mosaic images that are pre-rendered on the server.


In the context of ArcGIS Server, an instance is a single process run by ArcGIS Server for a service to be used to process requests for the service's data.

IP Address

(Internet Protocol address). A numeric label that uniquely identifies a computer or other device connected to a network that uses Internet Protocol. For example, is an IP address. See also: Host Name.


The data in web maps is usually represented in layers. For example, roads would be on a separate layer from rivers and waterways and political boundaries would be on a separate layer from national parks. A Group Layer is group of several layers that look and behave like a single layer.

Locator Service

See Geocoding service.


Web-based maps are fundamentally different from paper-based maps in that they are both interactive and searchable. Web-based maps contain data in many forms, which can be searched and annotated.

Map service

Map services can be open source or proprietary and serve spatial data. Map services serve map and layer content and can be cached or dynamic. Map services support operations like exporting maps, identifying features, finding information, and querying on layers.

Map service request

Can be either an export, find, identify, or query operation performed on a map service. Any request to a map service for geodata or to interact with the service.

Print templates

A template that is used by VertiGIS Studio Printing when printing maps.

Processing time

The average time it takes for a response to return from a resource. The definition of the average response time depends on the resource. In the case of an ArcGIS Server, it is the processing time the server takes to execute a given process. In the case of a website or a service, it is the time it takes for a request to be sent and returned from that resource.


Refers to the report application, accessible from the Analytics server by navigating to the configured directory. It allows for analysis of the status and trends of various monitored resources.


These are monitored by Analytics such as servers, ArcGIS server, Enterprise Portals, ArcGIS Online accounts, Studio Web apps, and Studio Mobile apps.


(Representational State Transfer). An architectural style used for network applications. Communication between Portal, viewers, and ArcGIS Server is done using REST.


A web-based, REST-compatible representation of the configuration of one or more web mapping applications. The REST API is organized as a hierarchy (a tree). Analytics can obtain configuration information by making HTTP requests to the REST API.

REST Endpoint

The items in a REST API's hierarchy are called "endpoints". Each endpoint represents the configuration of a particular resource or operation in the site. Each endpoint has a unique URL, which enables viewers to identify individual endpoints.


In the context of web mapping, services are GIS resources that are located on a server and accessed over a network. Types of service include map services, feature services, and geocoding services.


A session starts whenever a monitored Studio application is opened or reloaded.


(Uniform Resource Identifier). A string that identifies a resource on a computer or computer network. URIs enable interactions over the Internet using protocols.


(Uniform Resource Locator). A type of URI. Commonly known as a web address.


Any person, either a visitor or a known user, who is logged into and using Portal, ArcGIS Online, or a VertiGIS Studio application.


Viewers are the web applications that end users run to interact with a site and its map.


A visitor to a monitored application, who does not necessarily need to be a signed in user.
