Overview
OpenShift provides log aggregation with the EFK stack. fluentd is used to capture logs from nodes, pods and application and stored log data in ElasticSearch. Kibana offers a UI for ElasticSearch. fluentd, ElasticSearch and Kibana are deployed as OpenShift pods, on dedicated infrastructure nodes. Logging components communicate securely. They are usually part of the "logging" namespace. Application developers can view the logs for projects they have view access for. Cluster administrators can view all logs.
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.
