For example, if you select the Cache - Cache Objects metric, the graph displays the top 10 cache targets. Select a metric from the View drop down list to see a graphical representation of the top 10 targets for the selected metric. The top components are listed in ascending or descending order depending on the metric selected and indicates how the top component data has been collected. Top Components: This region contains a graphical representation of the top 10 performing targets for a selected metric based on the latest available data from the OMS repository. You can use the Personalization feature to specify the key metrics that are to be included in the charts. Key Indicators: This region displays graphs with key metrics that indicate the health and performance of the cluster. Click on the link to drill down to the Incident Manager page. Overview of Incidents and Problems: This region lists any incidents that have occurred over the last 7 days and any problems in the cluster and its associated targets (nodes, caches, and hosts). If a Binary calculator is not used, a N/A will be displayed in this field. A numeric value is displayed only if a Binary calculator is used in cache configuration. Total Memory: The total memory in MB used by all the objects in the back caches. Total Objects: The total number of objects stored across all the back caches in the cluster. Click on the link to drill down to the All Caches page. Non Storage Nodes: The nodes that are not storage enabled such as proxy, client nodes, and so on.Ĭaches: The total number of caches in the cluster. As a result, when you click on the link, the number of nodes displayed may be lesser than the nodes shown in this table. Note: The Number of Nodes and Storage Nodes listed here may be different from the number of node targets that have been discovered. Click on the link to drill down to the Storage Nodes page. Storage Nodes: The number of storage enabled nodes in the cluster. Click on the link to drill down to the All Nodes page. Total Nodes: The total number of nodes in the cluster. This flag is enabled if all the hosts on which the cluster is running are monitored by Enterprise Manager. Click on the link to drill down to the Node Home page.Ĭluster Control: Indicates if the Start / Stop feature is supported by this cluster. Management Node: Shows the name of the management node and its status. Summary: The following details are displayed:Īvailability (%): The availability of the cluster over the last 24 hours.Īuto Detect Restarted Nodes: If the cluster has been started with an extendedMBean property, the Auto Detect Restarted Nodes property is enabled and a check mark is displayed.
