What is the primary role of the Cribl Stream?

Answer: Data routing and shaping

Cribl Stream is an observability pipeline that allows organizations to collect, process, and route machine data from any source to any destination. Its primary role is to provide granular control over data streams, enabling users to filter, enrich, transform, and route data efficiently before it reaches analytics platforms or storage, optimizing data flow and reducing costs.

Which component handles incoming data?

Answer: Input

In Cribl, the Input component is specifically designed to receive and ingest data from various sources. It acts as the initial entry point for all observability data, collecting it before it proceeds through the pipeline for processing and routing. This ensures that data from diverse origins can be brought into the Cribl environment.

What is the Leader Node responsible for?

Answer: Managing configuration and workers

The Leader Node in a Cribl distributed deployment serves as the central control plane. Its primary responsibility is to manage the overall configuration of the Cribl deployment, including pipelines, routes, inputs, and outputs. It also orchestrates the Worker Nodes, which perform the actual data processing tasks.

What is a Worker Node in Cribl?

Answer: Processes and routes data

A Worker Node in Cribl is the operational component responsible for executing the configured observability pipelines. It ingests data from inputs, applies transformations and filtering as defined in pipelines, and then routes the processed data to its designated destinations. Essentially, it's where the heavy lifting of data manipulation occurs.

Which UI is used to configure pipelines?

Answer: Web interface

Cribl Stream provides a comprehensive and intuitive web-based user interface (UI) for all configuration and management tasks. Users interact with this web interface to design pipelines, set up inputs and outputs, define routing rules, and monitor their entire Cribl deployment, making it the primary tool for interaction.

Which format does Cribl commonly use for structured logs?

Answer: JSON

JSON (JavaScript Object Notation) is a lightweight, human-readable data-interchange format that is widely used for structured logs. Cribl commonly uses JSON because it efficiently represents key-value pairs and nested data, making it ideal for easy parsing, processing, and transformation within the observability pipeline.

What is a pack in Cribl?

Answer: Reusable configuration bundle

A Pack in Cribl is a portable and reusable collection of Cribl configurations, such as pipelines, functions, routes, and knowledge objects. Packs allow users to share, deploy, and manage common configurations across different Cribl instances or for specific use cases, promoting standardization and efficiency in managing observability data.

Which protocol is supported for real-time log ingestion?

Answer: Syslog

Syslog is a standard protocol for sending log messages across an IP network, making it a ubiquitous source for operational data. Cribl supports Syslog as a common input source for real-time log ingestion, enabling it to collect event data from a wide range of network devices, servers, and applications efficiently.

Which Cribl tool provides observability pipeline functionality?

Answer: Cribl Stream

Cribl Stream is the core product that provides the observability pipeline functionality. It empowers users to ingest, process, route, and deliver data from any source to any destination, giving them granular control over their data streams before they reach their final analytics platforms or archives.
