Managing and monitoring clusters and cluster object health
Unified Manager uses periodic API queries and a data collection engine to collect data from the clusters. By adding clusters to the Unified Manager database, you can monitor and manage these clusters for any availability and capacity risks.
More information
Understanding cluster monitoring
You can add clusters to the Unified Manager database to monitor clusters for availability, capacity, and other details, such as CPU usage, interface statistics, free disk space, qtree usage, and chassis environmental.
Viewing the cluster list and details
You can use the Health: All Clusters view to view your inventory of clusters. The Capacity: All Clusters view enables you to view summarized information about storage capacity and utilization in all clusters.
Checking the health of clusters in a MetroCluster configuration
You can use Unified Manager to check the operational health of clusters, and their components, in a MetroCluster configuration. If the clusters were involved in a performance event detected by Unified Manager, the health status can help you determine whether a hardware or software issue contributed to the event.
Viewing the node list and details
You can use the Health: All Nodes view to view the list of nodes in your clusters. You can use the Cluster / Health details page to view detailed information about nodes that are part of the cluster that is monitored.
Generating a hardware inventory report for contract renewal
You can generate a report that contains a complete list of cluster and node information; such as hardware model numbers and serial numbers, disk types and counts, installed licenses, and more. This report is helpful for contract renewal within secure sites ("dark" sites) that are not connected to the NetAppActive IQ platform.
Viewing the Storage VM list and details
From the Health: All Storage VMs view, you can monitor your inventory of storage virtual machines (SVMs). You can use the Storage VM / Health details page to view detailed information about SVMs that are monitored.
Viewing the aggregate list and details
From the Health: All Aggregates view, you can monitor your inventory of aggregates. The Capacity: All Aggregates view enables you to view information about the capacity and utilization of aggregates in all clusters.
Viewing FabricPool capacity information
You can view FabricPool capacity information for clusters, aggregates, and volumes on the Capacity and Performance inventory and details pages for these objects. These pages also display FabricPool mirror information when a mirror tier has been configured.
Viewing storage pool details
You can view the details of the storage pool to monitor the storage pool health, total and available cache, and used and available allocations.
Viewing the volume list and details
From the Health: All Volumes view, you can monitor your inventory of volumes. The Capacity: All Volumes view enables you to view information about the capacity and utilization of volumes in a cluster.
Viewing details about NFS shares
You can view details about all NFS shares, such as its status, the path associated with the volume (FlexGroup volumes or FlexVol volumes), access levels of clients to the NFS shares, and the export policy defined for the volumes that are exported. Use the Health: All NFS Shares view to see all NFS shares on all monitored clusters, and use the Storage VM / Health details page to view all NFS shares on a specific storage virtual machine (SVM).
Viewing details about SMB/CIFS shares
You can view details about all SMB/CIFS shares, such as the share name, junction path, containing objects, security settings, and export policies defined for the share. Use the Health: All SMB Shares view to see all SMB shares on all monitored clusters, and use the Storage VM / Health details page to view all SMB shares on a specific storage virtual machine (SVM).
Viewing the list of Snapshot copies
You can view the list of Snapshot copies for a selected volume. You can use the list of Snapshot copies to calculate the amount of disk space that can be reclaimed if one or more Snapshot copies are deleted, and you can delete the Snapshot copies if required.
Deleting Snapshot copies
You can delete a Snapshot copy to conserve space or to free disk space, or you can delete the Snapshot copy if it is no longer required.
Description of cluster object windows and dialog boxes
You can view all your clusters and cluster objects from the respective storage object page. You can also view the details from the corresponding storage object details page.
