Accessing management hub logs
Red Hat® OpenShift® Container Platform logging service
To set up OpenShift Container Platform a cluster logging service, see the documentation for the supported versions:
Notes:
-
To install this service, you must adjust your cluster sizing. Follow the documented instructions to install a replicated Elasticsearch, Fluentd, and Kibana (EFK) stack.
-
Elasticsearch requires significant memory and storage capacity.
Basic logging
Each Open Horizon (Open Horizon) pod sends logs to STDOUT, so they can be read with the oc logs command. Basic logging capacity is limited, and log-rotation is based on time and log output quantity.
Determine the pod that you want to obtain the logs for:
oc get pods --namespace kube-system | grep ibm-edge
This sample shows truncated output.
$ oc get pods --namespace kube-system | grep ibm-edge
ibm-edge-agbot-5f96655f47-6g97f 1/1 Running 0 5h16m
ibm-edge-agbot-5f96655f47-jzdfv 1/1 Running 0 5h16m
ibm-edge-agbotdb-create-cluster-4mk7m 0/1 Completed 0 7d
ibm-edge-agbotdb-creds-gen-rfhd2 0/1 Completed 0 7d
ibm-edge-agbotdb-keeper-0 1/1 Running 0 7d
...
Tail the last 10 lines of the log for the first agbot pod in the previous list.
oc logs ibm-edge-agbot-5f96655f47-6g97f --tail=10
This sample shows an example of output.
$ oc logs ibm-edge-agbot-5f96655f47-6g97f --tail=10
