ClusterView: An Example of an Integrated Map Application
The ClusterView application is integrated into OpenView Network Node
Manager and allows to display and monitor MC/ServiceGuard clusters
from the HP OpenView environment in a distributed commercial
environment. An MC/ServiceGuard cluster is a loosely defined collection
of nodes that assure the availability of a common set of High Availability
Services by using replicated hardware resources (CPUs, LAN cards,
shared disks) and MC/ServiceGuard specific processes that monitor
registered services.
The ClusterView Map-application clusmap uses the OpenView Windows
API to create its own submaps and symbols that represent
MC/ServiceGuard clusters. In the root-submap, it places an explodable
“Clusters” Symbol next to the “IP Internet” symbol to allow the user to
access the cluster hierarchy. Like the ipmap Map-application that sets
the color of the symbols under the “IP Internet” symbol, the clusmap
application sets the color of the symbols under the “Clusters” symbol
according to the status of the MC/ServiceGuard elements.
Figure 6-3 Root Submap Showing ClusterView Symbol
The user can double click on the Clusters icon to reach the Clusters
submap which contains a symbol for each discovered MC/ServiceGuard
cluster. The cluster icons in this submap are automatically placed in this
submap for all clusters auto-discovered by the ClusterView process
clusmon. Status changes will be reflected by the color of the cluster icons.
This screen can be used to drill down to get information on each cluster:
a double click on the MC/ServiceGuard Cluster icons will bring the user
to the “MC/ServiceGuard Cluster” submap.
