3 1. Purpose The Blue Medora VMware vrealize Operations (vrops) Management Pack for User Guide describes the primary features of the Management Pack for, including dashboards, views, reports, alerts, and metrics that allow users to optimize the monitoring and management of Aurora resources from within vrealize Operations. 2. Introduction to the Management Pack The Management Pack for is an embedded adapter for vrealize Operations (vrops) that monitors Aurora systems remotely. The Management Pack retrieves data regarding resources by connecting to each supported Aurora. This section includes the following topics: How the Management Pack Collects Data Data the Management Pack Collects Inventory Tree (Traversal Spec) 2.1 How the Management Pack Collects Data During each data collection cycle, the Management Pack opens a JDBC connection to the configured Aurora and queries it to retrieve metrics regarding Aurora resources. The collection interval for the adapter instance resource determines how often the Management Pack collects data. The default collection interval is five minutes. The Management Pack supports Autodiscovery and manual discovery of resources. When you enable Autodiscovery for an adapter instance, the Management Pack creates resources in vrealize Operations and collects data after the main collection query runs. If a new resource belongs to a resource kind that does not exist in vrops, the Management Pack creates the resource kind. 2.2 Data the Management Pack Collects The Management Pack can collect performance data, relationships, and events for the following Aurora resources: 1. Cluster Query 5. Table 3 Blue Medora VMware vrealize Operations Management Pack for User Guide

4 2.3 Inventory Tree (Traversal Spec) The Inventory Tree (Traversal Spec) feature within vrops allows you to easily navigate your environment. The hierarchical structure implicitly shows relationships among resource kinds and enables quick drill-downs to root-cause issues. Figure 1: Example Traversal Spec 4 Blue Medora VMware vrealize Operations Management Pack for User Guide

5 3. Dashboards Dashboards are the primary user interface that allow users to monitor resources from within vrealize Operations. The following dashboards are available in the Management Pack: Environment Cluster Analysis Analysis Query Analysis Table Analysis 3.1 Environment The Environment dashboard provides details about your resources.
