Overview
OpenShift provides log aggregation with the EFK stack. Logs from nodes, pods and application are captured, stored in ElasticSearch and exposed. Application developers can view the logs for projects they have view access for.
Logging support is not provided by default but it can be enabled during installation, by setting "openshift_hosted_logging_deploy=true" in the Ansible hosts file.
Logging support is provided by the Elasticsearch and Kibana pods. The logging pods should run on dedicated infrastructure nodes.
