Internal
Procedure
Installation During the Main Procedure
Logging must be explicitly enabled during the advanced installation, as described here:
Ansible installation deploys all resources needed to support the stack: Secrets, Service Accounts and DeploymentConfigs.
Installation Independent of the Main Procedure
There is also a dedicated Ansible playbook that can be used to deploy and upgrade logging independently of the main installation procedure:
ansible-playbook [-i </path/to/inventory>] /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/openshift-logging.yml
Post-Install Configuration
TODO this in the light of the fluentd DaemonSet reconfiguration:
In order for the logging pods to spread evenly across the cluster, an empty node selector should be used. The "logging" project should have been created already. The empty per-project node selector can be updates as follows:
oc edit namespace logging
...
metadata:
annotations:
openshift.io/node-selector: ""

Installation Validation
ElasticSearch
ElasticSearch should be deployed, running, and operational - logs must not contain errors:
oc project logging oc get pods -l 'component=es' oc logs -f logging-es-3fs5ghyo-3-88749
or
oc logs -f logging-es-data-master-ebitzkr3-1-x0jch
fluentd
All nodes should run a fluentd pod, and the fluentd pods should be operational, their logs must not contain errors.
oc project logging oc get pods -l 'component=fluentd' NAME READY STATUS RESTARTS AGE logging-fluentd-2r4rt 1/1 Running 0 49m logging-fluentd-37d72 1/1 Running 0 35m logging-fluentd-4ljkn 1/1 Running 0 3h logging-fluentd-74l39 1/1 Running 0 3h logging-fluentd-7l25h 1/1 Running 0 3h logging-fluentd-sbh7r 1/1 Running 0 3h logging-fluentd-w4shg 1/1 Running 0 39m

Kibana
ElasticSearch should be deployed, running, and operational - logs must not contain errors:
oc project logging oc get pods -l 'component=kibana' oc logs -f -c kibana-proxy logging-kibana-10-sb7sk oc logs -f -c kibana logging-kibana-10-sb7sk
The Logging Portal
The logging portal should be available:
