Event Endpoint Management continues to be enhanced

Event Endpoint Management continues to be available and enhanced as part of IBM's integration platforms.

End of Marketing announcement for IBM Event Automation

Event Streams and Event Processing are deprecated and no enhancements will be provided. Support and security fixes will be provided in line with published support lifecycle policies. Future event-driven solutions that make use of Apache Kafka and Apache Flink will be delivered by IBM Confluent.

For more information, see the support lifecycle transition and software ordering completion announcement.

Attention: This version of Event Streams has reached End of Support. For more information about supported versions, see the support matrix.

The Messages page is blank

Symptoms

When using the Event Streams UI, the Messages page loads, but then becomes blank when viewing any topic (either real or simulated).

Causes

The vm.max_map_count property on one or more of your nodes is below the required value of 262144. This causes the message indexing capabilities to fail, resulting in this behaviour.

Resolving the problem

Ensure you set the vm.max_map_count property to at least 262144 on all IBM Cloud Private nodes in your cluster (not only the master node). Run the following commands on each node:
sudo sysctl -w vm.max_map_count=262144
echo "vm.max_map_count=262144" | tee -a /etc/sysctl.conf
Important: This property might have already been updated by other workloads to be higher than the minimum required.
