With WebSphere® Extended Deployment, you can manage complex system operations with real time, meaningful visualization tools. Gradually controlled implementation of autonomic capabilities helps you to reduce the cost of managing your resources.
Visualization in WebSphere Extended Deployment consists of both transient runtime configuration information and performance statistics. Each of these are provided for various perspectives, or levels. For instance, you can view the current workstation membership in a resource pool, the current WebSphere Application Server installations on a given workstation, or the current application installations in a given application server instance. Similarly, you can view utilization and performance statistics at the resource pool level, workstation level, application server instance level, or application level.
Manageability function
In addition to visualization, the runtime operations center will provide some administrative capability. With this module, you can view the actual distribution of applications on servers and other scenarios that are governed by runtime provisioning decisions. So, in addition to viewing the current state of the environment, an administrator is allowed to take some administrative action. For instance, an administrator can override decisions made by the provisioner or modify application priority with the operations console.
Customized charting and topology visualization
To realize the benefits of using a virtualized environment, it is important to know how your applications are performing. WebSphere Extended Deployment gives you a visual perspective of this performance. Specifically, statistics such as response time, traffic, and throughput might interest both administrators and application owners. You can choose different options to create various charts that show precise data. You can also configure the visualization data service to create logs of this data.
Node groups and dynamic clusters
Extended manageability in WebSphere Extended Deployment also supports node groups and dynamic clusters. A node group is a user defined collection of nodes that share a common property. A dynamic cluster is a container construct which extends its static counterpart, the static cluster, in WebSphere Application Server Network Deployment. Dynamic clusters are associated with a single node group. Dynamic clusters are application deployment targets that can expand and contract as needed by the dynamic operations environment. Also, a dynamic cluster can cross the boundaries of nodes within a node group.
