Glossary

Circuit Breaker: the circuit breaker protects a destination that is failing or overloaded from continued data delivery attempts.  The circuit breaker will trip when either of the following conditions are met: (1) `maxFailures` number of API failures have occurred, or (2) an API call has taken longer than `callTimeout` to complete.  Once tripped, the circuit breaker will attempt to reset after `resetTimout` time has expired. When the circuit breaker first resets, it goes into a `half-open` state that will allow the first call through and not allow subsequent ones. If the first call succeeds, it will move to a `fully-open` state and return to normal operation.

Collection: describes the execution of a task for a stream (for example: start the metrics collection in the AppDynamics > Micro Focus OpsBridge stream).

Data  Formats : any data format that a Source generates or a Destination ingests; examples: XML, JSON, CSV, log files, HTTP, JDBC, binary, etc.

Data  Types : data formats supported by the Source and/or Destination; Data Types include Data Types: Metrics, Events, Topology, Logs.

Destination Mediator: configurable distributed StreamWeaver software component that uniquely formats Data Types data for consumption by the Destination. 

Destination Transformer: feature of Destination Mediators used to transform Data Types data before delivery to the Destination.

Destination Endpoint: a 3rd-party application, tool, system, API, database, or other entity to which Data Types can be consumed.

Endpoints: 3rd-party Sources or Destinations.

Events: alerts and notifications created by an IT service management or monitoring application; used as a data format in the StreamWeaver Platform.

IT Operations software: represents all the applications IT needs to manage the provisioning, capacity, performance, and availability of the computing, networking and application environment.

Log (unstructured data): used as a data format in the StreamWeaver Platform.

Mediator: StreamWeaver software that manages data extraction from a 3rd-party source (source mediator) or ingestion into a 3rd-party destination (destination mediator).

Data Types: abbreviation for Metric, Event, Topology, Log: the Data Types with which the StreamWeaver Platform works. 

Metrics: quantity used to track and assess the status of a specific process; used as a data format in the StreamWeaver Platform.

Source Mediator: configurable distributed StreamWeaver software component that handles Data Types data collection from the Source.

Source Transformer: feature of Source Mediators used to transform Data Types data before delivery to Destination Mediator.

Source Endpoint: a 3rd-party application, tool, system, API, database, or other entity from which Data Types can be obtained.

Data Types Stream: configurable item representing the linkage and data transfer between endpoints: the Source and Destination.

StreamWeaver Platform: software that enables users to quickly and easily stream metric, event, log, and topology data from monitoring and domain management applications to AIOps, analytics, and visualization applications.

Task: scheduled unit of work related to a Mediator.

Topology: describes Configuration Items (CIs) and their inter-relationships (example: Application Server connected to Load Balancer VIP Port X); used as a data format in the StreamWeaver Platform.
