Kafka is a distributed streaming platform that can be used to integrate events coming from BPMN workflows and from ADS (Application Data Sources). The Kafka unified data model allows for the standardized and centralized handling of data from various sources, including BPMN workflows and ADS. This setup can be used to standardize and normalize the data, which can then be used for analytics, reporting, and real-time processing.

The Cloud Pak for Business Automation standard capabilities logging is enabled to collect and forward standard output to the specified logging destination when configured. This logging is not stored in a dedicated persistent data store unless specified, and is viewable only by the OpenShift Container Platform (OCP) web console.

If a new modification to a Deployment has rendered it unstable, then the best way to regain stability is to rollback to an earlier Deployment. Rolling back to a previous Deployment will restore the system to its previous configuration, which should restore stability. The other options are not related to this process.

If it is desired to use a root CA signer certificate that is signed by a recognized certificate authority, the rootcacertificate should be supplied as part of the custom resource prior to deployment. This is necessary in order for the root CA signer certificate to be validated.

Container Application Software for Enterprises (CASE) is a specification that defines the metadata and structure for packaging, managing, and unpacking containerized applications. CASE allows the creation of a standard format for containerized applications that can be easily shared and deployed across different environments. It defines the metadata, structure, and packaging of containerized applications, and provides a way to manage and distribute them across different platforms and environments.

To limit and secure integrations with an external service, the Cloud Pak for Business Automation operator root CA signer certificate should be provided to the external service provider to be configured. This establishes a trusted relationship between the Cloud Pak for Business Automation capability on OpenShift with the external service.

The Cloud Pak Foundation services monitoring stack includes Kibana, which is an open-source data visualization and exploration tool. It allows you to search, view, and interact with data stored in Elasticsearch indices. Kibana provides a web interface that enables you to create and share dynamic dashboards, visualizations, and search templates.

It's important to note that other tools such as Elasticsearch, Alertmanager, and Logstash are also part of the Cloud Pak Foundation services monitoring stack, but they have different functions.

When deploying License Service Reporter, the summary card additionally shows a View license usage link. This link leads to the License Service Reporter user interface that presents the license usage of your products within the reporting period for a multi-cluster environment. The license usage presented is Average Daily Usage, which is the average number of licenses used per day in the reporting period.

To generate a higher level of detail in operator logs, you can configure a detailed operator trace in a ConfigMap. This allows you to specify the level of logging for different components of the operator and can provide more information about the operator's behavior. The level of logging can be set to "debug", "info", "warning" or "error" in the ConfigMap. You can access the ConfigMap by using the "oc edit configmap" command and then editing the "loglevel" field.

It's also important to note that there are other ways to troubleshoot issues with operators and their logs, such as running the "oc logs" command on the operator pod, or using the "oc adm must-gather" command to collect cluster state and diagnostic information.

When performing an air-gapped upgrade of Cloud Pak for Business Automation, the images used for the upgrade reside in a local registry. An air-gapped environment is one in which there is no external network access, so the images cannot be pulled from a remote registry such as IBM registry, RedHat quay.io registry, or Docker Hub. Instead, the images must be pre-pulled and stored in a local registry that is accessible to the OpenShift cluster.
