Kibana is the visualization and user interface component of the Elastic (EFK) stack, which is utilized by the IBM Cloud Pak for Integration logging service. Its primary role is to provide a web-based interface that allows users to interact with the log data stored in Elasticsearch. Through Kibana, users can perform complex searches, explore and discover patterns in the log data, and create custom dashboards with various visualizations like charts, graphs, and maps to monitor and analyze the logs in real-time.

A. Collate, correlate, and interpret log data: This describes a broader log management or SIEM function; Kibana is specifically the front-end tool for querying and visualization, not the engine for correlation.

B. Capture, collect, and forward log data: This is the function of the log shipper or agent in the stack, such as Fluentd or Filebeat, which gathers logs from sources and sends them to be stored.

C. Index, search, and store log data: This is the core function of Elasticsearch, the distributed search and analytics engine that acts as the data store for the logging service.

1. IBM Cloud Pak for Integration Documentation - Logging: "The logging service is based on the Elasticsearch

Fluentd

and Kibana (EFK) stack... Kibana is the web UI that you use to query and visualize your logs." This statement directly confirms Kibana's role as the query and visualization tool.

"Logging". (Specific version documentation may vary

but the description of the EFK stack components is consistent across versions

e.g.

2021.4).

2. Red Hat OpenShift Container Platform Documentation - About the logging subsystem: Since IBM Cloud Paks are built on OpenShift

its documentation on the EFK stack is authoritative. "The logging subsystem is composed of a collector

a log store

and a visualization tool... The visualization component is Kibana."

Section: "Observability" -> "About the logging subsystem".

3. Elasticsearch B.V.

"What is Kibana?": As the official vendor documentation for the component itself

this is a primary source. "Kibana is a free and open user interface that lets you visualize your Elasticsearch data and navigate the Elastic Stack. Do anything from tracking query load to understanding the way requests flow through your apps."
