You can use the Health/Aggregate details page to view detailed information about the selected aggregate, such as the capacity, disk information, configuration details, and events generated. You can also view information about the related objects and related alerts for that aggregate.
The command buttons enable you to perform the following tasks for the selected aggregate:
Enables you to add an alert to the selected aggregate.
Enables you to modify the threshold settings for the selected aggregate.
The Capacity tab displays detailed information about the selected aggregate, such as its capacity, thresholds, and daily growth rate.
By default, capacity events are not generated for root aggregates. Also, the threshold values used by Unified Manager are not applicable to node root aggregates. Only a technical support representative can modify the settings for these events to be generated. When the settings are modified by a technical support representative, the threshold values are applied to the node root aggregate.
Displays the space used by data in the aggregate.
Indicates that the space in the aggregate is overcommitted.
Indicates that the space in the aggregate is nearly full. If this threshold is breached, the Space Nearly Full event is generated.
Indicates that the space in the aggregate is full. If this threshold is breached, the Space Full event is generated.
Displays the total data capacity and the used data capacity of the aggregate. If the aggregate is overcommitted, a flag is displayed with the overcommitted capacity.
This graph is displayed only when the used Snapshot capacity or the Snapshot reserve is not zero.
Both of the graphs display the capacity by which the Snapshot capacity exceeds the Snapshot reserve if the used Snapshot capacity exceeds the Snapshot reserve.
Displays the space used by data in the external capacity tier.
Displays the space in the external capacity tier for an Amazon S3 FabricPool that cannot be used. This space may be shared with another FabricPool-enabled aggregate.
For an Amazon S3 FabricPool, the chart displays the total data capacity that has been licensed by this cluster, the amount being used by this aggregate, and the unusable amount from other aggregates that are using the external capacity tier.
For a StorageGRID FabricPool, the chart displays only the total capacity being used by this aggregate.
Displays the total capacity in the aggregate.
Displays the amount of space used by the aggregate (used capacity) and the amount of available space in the aggregate (free capacity).
Displays the used and free Snapshot capacity of the aggregate.
For an Amazon S3 FabricPool, displays the total licensed capacity, the amount used by this aggregate, the amount used by other aggregates, and the free capacity for the external capacity tier. For a StorageGRID FabricPool, displays only the total capacity being used by this aggregate.
Specifies the percentage at which an aggregate is nearly full.
Specifies the percentage at which an aggregate is full.
Specifies the percentage at which an aggregate is nearly overcommitted.
Specifies the percentage at which an aggregate is overcommitted.
Displays the disk space used in the aggregate if the rate of change between the last two samples continues for 24 hours.
For example, if an aggregate uses 10 GB of disk space at 2 pm and 12 GB at 6 pm, the daily growth rate (GB) for this aggregate is 2 GB.
Displays the number and capacity of the volumes that are being moved out of the aggregate.
You can click the link to view more details, such as the volume name, aggregate to which the volume is moved, status of the volume move operation, and the estimated end time.
Displays the number and remaining capacity of the volumes that are being moved into the aggregate.
You can click the link to view more details, such as the volume name, aggregate from which the volume is moved, status of the volume move operation, and the estimated end time.
Displays the estimated amount of used space (as a percentage, and in KB, MB, GB, and so on) in the aggregate after the volume move operations are complete.
You can select the graph you want to view from the drop-down lists. You can sort the data displayed in the graph to display details such as the used size, provisioned size, available capacity, fastest daily growth rate, and slowest growth rate. You can filter the data based on the storage virtual machines (SVMs) that contain the volumes in the aggregate. You can also view details for thinly provisioned volumes. You can view the details of specific points on the graph by positioning your cursor over the area of interest. By default, the graph displays the top 30 filtered volumes in the aggregate.
Displays detailed information about the disks in the selected aggregate, including the RAID type and size, and the type of disks used in the aggregate. The tab also graphically displays the RAID groups, and the types of disks used (such as SAS, ATA, FCAL, SSD, or VMDISK). You can view more information, such as the disk's bay, shelf, and rotational speed, by positioning your cursor over the parity disks and data disks.
RAID details are displayed only for dedicated disks.
Displays the RAID type (RAID0, RAID4, RAID-DP, or RAID-TEC).
Displays the maximum number of disks allowed in the RAID group.
Displays the number of RAID groups in the aggregate.
Displays the types of data disks (for example, ATA, SATA, FCAL, SSD, or VMDISK) in the aggregate.
Displays the number and capacity of the data disks that are assigned to an aggregate. Data disk details are not displayed when the aggregate contains only shared disks.
Displays the number and capacity of the parity disks that are assigned to an aggregate. Parity disk details are not displayed when the aggregate contains only shared disks.
Displays the number and capacity of the shared data disks that are assigned to an aggregate. Shared disk details are displayed only when the aggregate contains shared disks.
The following details for the dedicated cache SSD disks are displayed:
Displays the RAID type (RAID0, RAID4, RAID-DP or RAID-TEC).
Displays the maximum number of disks allowed in the RAID group.
Displays the number of RAID groups in the aggregate.
Indicates that the disks used for cache in the aggregate are of type SSD.
Displays the number and capacity of the data disks that are assigned to an aggregate for cache.
Displays the number and capacity of the parity disks that are assigned to an aggregate for cache.
Displays the name of the node that contains the selected aggregate.
Displays the block format of the aggregate: either 32-bit or 64-bit.
Displays the RAID type (RAID0, RAID4, RAID-DP, RAID-TEC or Mixed RAID).
Displays the size of the RAID group.
Displays the number of RAID groups in the aggregate.
Displays the SnapLock Type of the aggregate.
Displays the name of the object store when it was created by ONTAP.
Displays the name of the storage provider, for example, StorageGRID or Amazon S3.
Displays the FQDN of the object store.
Displays the access key for the object store.
Displays the bucket name of the object store.
Displays whether SSL encryption is enabled for the object store.
The History area displays graphs that provide information about the capacity of the selected aggregate. Additionally, you can click the Export button to create a report in CSV format for the chart that you are viewing.
You can select a graph type from the drop-down list at the top of the History pane. You can also view details for a specific time period by selecting either 1 week, 1 month, or 1 year. History graphs can help you identify trends: for example, if the aggregate usage is consistently breaching the Nearly Full threshold, you can take the appropriate action.
History graphs display the following information:
Displays the used capacity in the aggregate and the trend in how aggregate capacity is used based on the usage history as line graphs, in percentage, on the vertical (y) axis. The time period is displayed on the horizontal (x) axis. You can select a time period of a week, a month, or a year. You can view the details for specific points on the graph by positioning your cursor over a particular area. You can hide or display a line graph by clicking the appropriate legend. For example, when you click the Capacity Used legend, the Capacity Used graph line is hidden.
The Related Alerts pane enables you to view the list of alerts that are created for the selected aggregate. You can also add an alert by clicking the Add Alert link or edit an existing alert by clicking the alert name.
