Connect and select clusters to be monitored
Connect to the OM on a ServiceGuard node with valid user name and password (root or non-root)
User can specify which clusters to monitor, choosing from all the clusters that can be discovered by the OM.

Property Sheet
• Every map object has its own property sheet
• A property sheet is a collection of property tabs
• Two types of tabbed pane:– List tab– Table tab
• Psheet status:– Progress bar– Text panel to display
status messages• Save shows the ASCII
summary information of the property sheet

SNMP Event Notification
• Receives snmp traps from the nodes monitored
• Notifies the user of the status change
• Triggers refresh when a SG-related trap received
• Use Event Browser to see traps received (500 entries)
• All traps are logged in log files• Support HP-UX clusters only

ServiceGuard Manager Security
SG Manager allows you to limit the clusters to be managed based on customer security requirements.
The OM cannot return information about a node without the node's permission. The OM node must be listed in .rhosts or in /etc/cmcluster/cmclnodelist of each node to be discovered.
Passwords are encrypted before they are sent over the network, and if they are saved for the next session.
SNMP event notification: set-community name required to receive traps
Only the root user has administration capabilities.
