以下是訪問Opscenter的流程：

kubectl get svc  -o wide -A

By this command you will get all the pods with their IPs and name

ssh -p 2024 admin@<ops-center pod IP>

Here port is 2024 and user is admin for opscenter and IP we can get from svc command

cat /etc/smi/rcm-image-version

To check RCM version which can be directly executed on RCM but verify the file name : “rcm-image-version” once in the same path as file name can be different for different customers

systemctl status kubelet                    -------------- kubelet statistics

systemctl status host_reboot.service        ------------- to check status of Active RCM

kubectl get pods -A                         ------------- list of pods created in the node

kubectl describe pod <pod name> -n rcm      ------------- shows details of each container in this pod

kubectl get svc  -n rcm                     ------------- To get service IP and port of container

ssh -p 2024 admin@<pod IP>                  ------------ Get into that Pod

kubectl get cm –n rcm                       ------------ To check different config maps

kubectl logs <pod name> -n rcm              ------------- to check pod level logs
