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, metrics, and alerts that allow users to optimize the monitoring of their 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 remotely. The Management Pack retrieves data regarding resources by connecting to each supported instance. This section includes the following topics: How the Management Pack Collects Data Data the Management Pack Collects 2.1 How the Management Pack Collects Data During each data collection cycle, the Management Pack opens a Nitro REST API connection to the configured appliance and queries it to retrieve metrics regarding 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. Figure 1: Example Traversal Spec 2.2 Data the Management Pack Collects The Management Pack can collect performance data, relationships (associations), and events for the following resources: 1. Adapter Instance 2. NetScaler 3. High Availability Group 4. Load 5. Load 6. Target 7. Balancing (GSLB) Site 8. GSLB Virtual 9. GSLB Service 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. 3 Blue Medora VMware vrealize Operations Management Pack for User Guide

13 8. Troubleshooting the Management Pack Known troubleshooting information can help you diagnose and correct common problems with the Management Pack for. This section includes the following topics: Troubleshooting an Adapter Instance Testing Connection Failures Viewing System Log Files 8.1 Troubleshooting an Adapter Instance Perform these general troubleshooting steps to diagnose and correct problems with an adapter instance: Edit the adapter instance and click Test Connection to verify the connection to vrops. Refer to section 8.2 Testing Connection Failures. View the collection status and collection state for the adapter instance resource on the Environment Overview page in vrops. Check the adapter and collector logs for errors. Refer to section 8.3 Viewing System Log Files. 8.2 Testing Connection Failures Click Test Connection in the Manage Solution window when adding an adapter instance to ensure data will be retrieved. The following errors are possible when testing the connection: Error connecting to Netscaler. Proposed action: Ensure the appliance IP address is correct. Error logging in to NetScaler. Proposed action: Ensure the User Name and Password are correct. Unable to establish a valid connection to the system using SSL. Please confirm that the NetScaler is using uncompromised cipher suites. For more information see the user guide. Proposed action: Make sure the NetScaler server is configured to use uncompromised cipher suites. The RC4 cipher suite is considered compromised by vrops 6.2, and will not support data collection. Earlier versions of vrops may support it, but this is not recommended. Cipher suites can be set on the NetScaler server on the tab under Traffic Management > SSL > Cipher Groups. Unable to establish a valid connection to the target system using SSL. For more information see the user guide. Proposed action: Add the NetScaler server certificate to the Java truststore on the vrops machine, or set Validate Certificate Against Truststore to False in the Manage Solution window. 8.3 Viewing System Log Files You can view adapter errors in the adapter and collector log files. You can view the adapter and collector log files in the vrops user interface or in an external log viewer. The adapter log files are in the $ALIVE_BASE/user/log/adapters/CitrixNetScalerAdapter/ folder. The collector log files are in the $ALIVE_BASE/user/log/ folder. The logging level is set to ERROR by default. To troubleshoot issues, set the logging level to INFO. To view detailed messages, including micro steps, queries, and returned results, set the logging level to DEBUG. You can set the base log level for the collector via Administrator > Support > Logs > Select COLLECTOR folder > Select Edit Properties icon > Edit Root logger level. NOTE: If you set the logging level to DEBUG, log files can become large very quickly. Set the logging level to DEBUG only for short periods of time. For complete information about viewing log files and modifying log levels, refer to the vrops online help. 13 Blue Medora VMware vrealize Operations Management Pack for User Guide
