Grafana dashboard

Learn about the dashboard features that you can use to monitor and optimize your storage environment.

The IBM Storage Insights dashboard in Grafana is divided into two sections:

Tenant level summary information

It provides the data across all block storage systems within a tenant, such as block storage health, capacity information, alerts including security alerts (if any), and other details. This holistic view of resource utilization aids in capacity planning and optimization. It provides the consolidated information of all the block storage systems that is added to the tenant.

Tenant summary
Table 1. Tenant Level Summary Information
Menu item Sub menu item Description
Block storage - It displays the number of block storage devices.
Block Storage Health - Block Storage Health details the health condition of all the devices of the tenant in a pie chart.
Total Systems Capacity Available Capacity The amount of unused capacity in the storage system that is reserved for provisioning and optimization tasks.
Used Capacity The percentage of physical capacity that is used, including overhead capacity. The value is always less than or equal to 100% because you cannot use more physical capacity than what is available.
Total Capacity The total capacity in the storage system.
Data Reduction - It is used to reduce the amount of usable capacity that is required to store data.
Data Provisioned - Total capacity of all volumes that are created on the system, which includes volumes that are not mapped to hosts.
Total Savings - The total amount of usable capacity that is saved in a pool, system, or volume through thin-provisioning and data reduction techniques. This saved capacity is the difference between the used capacity and the total provisioned.
Host Capacity Mapping Mapped Capacity The total volume space in the storage system that is mapped or assigned to storage systems.
Unmapped Capacity The total volume space in the storage system that is not mapped or assigned to storage systems.
Alerts - The Alerts pane displays the count of Critical, Warning, and Informational alerts for all block storage devices over the last 24 hours, along with their acknowledged status.
Security Alerts -

Security alerts indicate the total number of potential ransomware attacks across various IBM Storage Virtualize and IBM Storage FlashSystem products on the tenant.

System Level Information

It displays the data for selected individual storage devices, such as capacity information, security alerts (if any), and so on. This aids detailed analysis and monitoring of specific systems that supports better management and optimization of storage resources. It has the following panels:

Table 4. Internal Resources
  Sub menu item Description
Volumes Count Volume Name The name or label of the volume, if available. This value uniquely identifies the volume within the storage system.
Volume ID The identifier for the volume as defined on the storage system. The volume ID might be a serial number or internal ID.
Status The status of a volume. Statuses include Normal, Warning, Error, Unknown, Online, Offline, Syncing, Degraded, Excluded, Unreachable. The (Threat Detected) label is appended to existing statuses in the Status column. For instance, if a volume's status is Warning and ransomware threat is detected on it, the status displays as Warning (Threat Detected). If you acknowledge the alert, then the status becomes Warning (Threat Detected) Acknowledged. Use the status to determine the condition of the volume, and if any actions must be taken.
Pool Name The name of the pool that contains the volume from the storage system that is mapped to the disk.
Hosts The name of the host, as defined on the storage system host connection.
Compressed It indicates whether the volume is compressed or not.
IO Group Each pair of nodes within a single enclosure is known as an input/output (I/O) group.
Node The nodes that form the I/O group.

  • ESE: The volume is an Extent Space-Efficient (ESE) thin-provisioned volume on a DS8000 storage system.
  • No: The volume is not a thin-provisioned volume. TSE The volume is a Track Space-Efficient.
  • TSE: The volume is a Track Space-Efficient (TSE) thin-provisioned volume on a DS8000 storage system.
  • Yes: The volume is a thin-provisioned volume.

Status The status of the FC port. Statuses include Not Normal, Warning, Error.
Speed (GB/S) FC port speed in Gigabits per second.
Drives Count Name The name or label of the drive.
Status The status of a disk or drive. Use the status to determine the condition of the disk or drive, and if any actions must be taken. For example, if a disk has an Error status, take immediate action to correct the problem. If the disk has an Operational status, then it is operating normally and no further action is required.
RAID Array Name of the RAID Array to which the drive belongs.
Class The technology type of the disk or drive, such as Solid-State Drive, NVMe SSD, Storage Class Memory, Flash, Fibre Channel (FC), SATA, and other types.
Speed (RPM) The number of revolutions per minute of a disk.
Capacity (GiB) For uncompressed disks or drives, the capacity is the same as the physical capacity and represents the total amount of unformatted storage space.

For compressed disks or drives, the capacity is the estimated amount of data that can be written to the disk or drive. This value is larger than the physical capacity because drive compression is used to reduce the size of the data.
Encryption It indicates whether the drive is encrypted or not.
Vendor The name of the vendor.
Model The model number.
Serial Number The serial number of the drive.
Firmware Shows the firmware information.
Compressed Shows whether the disk or drive uses inline data compression to automatically compress the data that is written.
IP Ports Count Name The name of the IP port.
Ackno It displays whether a user marked the status of an IP port as acknowledged. An acknowledged status indicates that the status was reviewed and is either resolved or can be ignored.

An acknowledged status is not used when the status of related, higher-level resources is determined. For example, if the status of an IP port is Error, then the status of the related storage system is also Error.

If the Error status of the IP port is acknowledged, then its status is not used to determine the overall status of the storage system. In this case, if the other internal resources of the storage system are Normal, then the status of the storage system is also Normal.
IQN The iSCSI qualified the name of the port.
Host Attach It indicates whether the port is configured to attach to hosts.
Storage Attach It indicates whether the port is configured to attach to storage.
Management It indicates whether the port is configured for management commands, or whether it is used only for management commands.
Node The node to which the port is connected.
Speed(GB/S) The negotiated speed of the link between the port and the node.
Status It indicates the configuration status and the link state of an IP port. Use the status to determine the condition of the port, and if any actions must be taken.

For example, if an IP port has an unconfigured status you might want to investigate why no iSCSI address is configured for the port. Also, if an IP port has an inactive status you might want to investigate why the port link is not active.
storage_system The name of the storage system.
MDisks Count Name The name of MDisk.
Available Capacity The amount of usable capacity that is not yet used in the MDisk.
Capacity (GiB) Total amount of storage space on a managed disk.
Class The technology type of the managed disk, such as Tier 0 and Tier 1 flash solid-state drives (SSDs), NVMe SSDs, Storage Class Memory, Enterprise and Nearline hard disk drives (HDDs), and other types. Managed disks that consist of internal, local disks are classified automatically by the cluster, but you must manually classify managed disks that consist of external disks.
Drive Compression The ratio of the uncompressed data size and the compressed data size for a particular managed disk in a storage system.
Mode The allocation mode of the managed disk. The following allocation modes might be shown:
  • Unmanaged: The external volume is virtualized as a managed disk, but is not being used.
  • Managed: The external volume is virtualized as a managed disk and is assigned to a pool or a managed disk group.
  • Image: The external volume is not virtualized, which means that the associated volume provides a direct block-for-block translation of the external volume.
  • Array: One or more internal or local disks are used to form the managed disk.
Pool The name of the managed disk group to which a managed disk belongs. If a managed disk is associated with a primordial pool, or is not yet assigned to a pool, then it is unmanaged. The value None is displayed.
Status The status of a managed disk. Use the status to determine the condition of a managed disk, and if any actions must be taken. For example, if a managed disk has an Error status, take immediate action to correct the problem.
Total Compression The ratio of the uncompressed data size to the compressed data size for all the managed disks in a storage system.
Volumes The number of volumes that are partially or completely on a managed disk.
Important: You can configure the Grafana dashboard by adding a new pane or column. To access the data, see IBM Storage Insights REST API Swagger document.
