Compaq ProLiant 6400R Compaq's Cluster Management Initiative - Page 5

(Figure 1 - Cluster Monitor Introduction Screen) The main Cluster Monitor screen is shown in Figure 1. In the upper left-hand corner is the Cluster Problem window that displays a prioritized listing of all cluster events by severity level. This allows the administrator to work efficiently by addressing cluster problems in order of severity, attacking the most critical cluster problems first. The administrator has a scroll bar so they can choose which events to work but it is displayed in most critical order based on clusters defined in the query. Compaq has color-coded the events in order to make it easy to recognize those most critical to smooth cluster operations. Clusters are displayed in a tree topology in the lower left section the Cluster Monitor screen. The topology tree and the clusters displayed are depicted in an iconic form, which includes the name of the cluster, the cluster condition, and the Cluster Manager Extensions selected for the specific cluster node or cluster itself. In order to help the administrator visualize what event(s) or device(s) are making the cluster unstable, Compaq has provided a set of selectable monitor programs for systems devices, and cluster manager health. The programs, Cluster Manager Extensions, can be applied to an individual cluster or to an individual node in a cluster. This is a powerful, yet simple approach that delivers a comprehensive view of the cluster that assists the administrator in making the proper problem determination and resolution decisions.
