Key Terminology
Get to grips with these key concepts to better understand how Onum works and use it to its full potential.
Action
A unit of work performing a given operation on an event.
API
Application Programming Interface. A set of defined methods of communication among various components.
Cluster
Various distributors and workers can be grouped and contained within a cluster. You can have as many clusters as required per Tenant.
Data sink
Where the data is routed after being processed by Onum.
Data source
Where the data is generated before ingesting it into Onum, e.g. application server logs, firewall logs, S3 bucket, Kafka Topic, etc.
Distributor
This service receives and processes the Listener data before sending it on to workers within a cluster.
Event
An event represents semi-structured data such as a log entry. Events can be parsed so that structured data can be generated and eventually processed by the engine. Events are composed of fields, which are referred to as Field. An action that produces a new field will be referred to as outputField.
Label
Used to sort events coming from Listeners into categories or sets that meet given filters to be used in a Pipeline.
Listener
A Listener retrieves events in a given IP address and a port, routing the data to the Pipelines so that it can be processed.
Lookup
A lookup refers to searching for and retrieving information from a specific source or dataset, typically based on a key or reference.
Multitenancy
Multitenancy is an architecture in which tenants share the same underlying infrastructure, including databases and application code, but their data and configurations are kept separate to ensure privacy and security.
Pipeline
A sequence of Actions connected through inputs/outputs to process a stream of data. Data comes from the Listener and eventually is routed to a Datasink.
Role
A role is assigned to a user in order to control the access they have to certain or all Onum features. This way, we can personalise the experience for each user.
Tag
Tags can be assigned to Listeners, Pipelines or Data sinks in order to classify them or make them easier to find. This is particularly useful if you have a wide database and want to avoid lengthy searching for the resources you wish to use.
Tenant
A Tenant is a domain that contains a set of data in your organization. You can use one or various tenants and grant access to as many as required.
Worker
This service runs the Pipelines, receiving data from its distributor and contained within a Cluster.
