Agent: 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 excluding the Hub server.


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.


Average response 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.


Authentication: 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.


Collection interval: The period of time between collections of information from a resource by Analytics. For example, the default collection interval of Websites is 15 minutes, which means that your websites are checked every 15 minutes.


Cumulative processing time: A metric to indicate performance of a service. It takes into account the total time spent processing a service on the server for the time period selected. The processing refers to the activity of the ArcGIS Server when it calculates service information. Cumulative refers to the fact that, if a service is requested three times, all three processing times are added together.


Default website settings: Default website settings affect all websites. Default website settings are used for checking websites. You can override Default settings with settings for specific websites.


Dependency: 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. Dependencies can be seen in the tab of an expanded resource (services).


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


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


Instance: In Analytics, the term 'instance' describes each installation of a program or resource. An instance could also be described as a single copy of a running program.


Instant search: The Essentials component that handles faster searches by building a local index of features in the Document Store.


Invalid status code: Refers to response codes that are considered invalid and can trigger alarms. Any response code that is 400 or above, is considered an invalid status code. Some exceptions in the 401 response code exist, depending on the resource.


Invocation: Equivalent to a request, for example, invoke a workflow / request a workflow.


Feature service: An ArcGIS service that contains features. A feature service is usually a resource located on a server and accessed over a network that serves map features, feature attributes, geometries, and symbology.


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.


Locator Service: See Geocode service.


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 geo data or to interact with the service.


Parent/Child Resources: A parent resource owns or references other resources, for example, a server that has an Essentials instance installed on it. The Essentials Instance in turn, would be the parent of an Essentials Site, which would be the parent of a service the site uses. There are two kinds of child resources; owned children and referenced children. A service that is hosted on an ArcGIS Server is an example of an owned child resource. A service that is used by an Essentials Site is a referenced child resource.


Print templates: A template for printing that is added to a Site in Geocortex Essentials and used by the Geocortex Viewers when printing maps.


Referenced services: Referenced services are services that Analytics discovers automatically from Portal for ArcGIS, ArcGIS Online, Essentials Sites, Viewers or Web Applications, but are not explicitly added to Analytics. For example, if you add a Portal for ArcGIS Server that is referencing an ArcGIS Server, the services in the Portal for ArcGIS Server are considered referenced services.

Referenced services alarms: In the Analytics context, a referenced service is one that an application is using, in other words, they are services that are referenced, or used by, a particular application. Alarms can be set to trigger if a referenced service is too slow or does not respond at all.


Remote collection / monitoring: Refers to resources that are monitored by Analytics without having an Analytics agent installed. Information is collected by configuring all the settings needed to connect to the server from the Analytics Configuration page in order to connect the server to the Analytics Hub via the Internet or through a network.


Reports: Refers to the report application, accessible from the Analytics server by navigating to http://localhost/AnalyticsReports


Session: A session starts whenever a monitored Geocortex or Web Application is opened or reloaded.


Sites: In the context of Analytics, this refers to Sites set up in Essentials. A site specifies the location and configuration of a GIS application that can include layered maps linked to map services, workflows, data links, and print templates. Maps can include ArcGIS Web Maps, feature services and images services.


SMS: Short Message Service—commonly referred to as a text message—of up to 160 characters sent from one device to another via the Internet. Devices can include cell phones, tablets, or desktop computers. Analytics uses Twilio as an SMS gateway that makes it possible for you to receive alarm notifications for critical issues via SMS.


User: Any person, either a visitor or a known user, who is logged into and using a Geocortex or a Web Application.

New user: The first time Analytics detects that this user has visited the application. Users are browser based. So opening a new application in Chrome, and then Firefox would be seen by Analytics as two new users of the application. The assumption is that most people use one browser.

Returning user: When a known user returns to an application, they are seen as a returning user. A returning user is a user who accessed the application before the selected time interval. Alternatively, if a user accesses the application two times or more in this time span and has not accessed it before, the first time the user is seen as a new user and for all subsequent times they are seen as a returning user.

Unique user: If a user uses an application three times within the date range selected, they are considered a single unique user.


Viewer: Refers to an Essentials viewer added to an Essentials site—either the Geocortex Viewer for Silverlight or the Geocortex Viewer for HTML5. Viewers serve as the interface for delivering Sites configured in Geocortex Essentials.


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


VTE: The Viewer Template Engine—the file that is used to install a new viewer (or upgrade an existing one) on your Essentials server.


Workflows: An Essentials workflow that has been added to an Essentials site.
