Viewing the cluster state

You can view the state of the cluster in two ways - based on your operating system or with a web based console provided by SUSE.

Operating system based

There are multiple operating system commands that can be run as root or as a user with appropriate permissions. The commands enable you to get an overview of the status of the cluster and its services. See the following commands for more details.

SUSE Hawk2

Hawk2 is a web-based graphical user interface for managing and monitoring pacemaker highly availability clusters. It must be enabled on every node in the cluster, to point your web browser on any node for accessing it. Use the following command to enable Hawk2.

# systemctl enable --now hawk
# systemctl status hawk

Use the following URL to check security groups for access on port 7630 from your administrative host.

https://your-server:7630/

e.g https://hanahost01:7630
