Metrics in the Block and File dashboard

Learn how to navigate Block and File dashboard in the OpenShift Web Console.

You can navigate to the Block and File dashboard in the OpenShift Web Console as follows:

Go to Storage > Data Foundation.
In the Status card of the Overview tab, click Storage System and then click the storage system link.
Click the Block and File tab.

The following cards on the Block and File dashboard provides the metrics based on deployment mode (internal or external):

Details card

The Details card shows the following:

Service Name
Cluster name
The name of the Provider on which the system runs (example: AWS, VSphere, None for Bare metal)
Mode (deployment mode as either Internal or External)
Fusion Data Foundation operator version.
In-transit encryption (shows whether the encryption is enabled or disabled)

Inventory card

The Inventory card shows the number of active nodes, PVCs and PVs backed by Fusion Data Foundation provisioner. On the left hand side of the card, total number of storage nodes, PVCs and PVs are displayed. While on the corresponding right hand side of the card, number of storage nodes in Not Ready state, count of PVCs in Pending state and PVs in Released state are shown.

Note: For external mode, the number of nodes will be 0 by default, since there are no dedicated nodes for Fusion Data Foundation.

Status card

This card shows whether the cluster is up and running without any errors or is experiencing some issues.

For internal mode, Data Resiliency indicates the status of data re-balancing in Ceph across the replicas. When the internal mode cluster is in a warning or error state, the Alerts section is shown along with the relevant alerts.

Note: For external mode, Data Resiliency and alerts will not be displayed.

Raw Capacity card

This card shows the total raw storage capacity which includes replication, on the cluster.

Note: This card is not applicable for external mode clusters.

Used legend indicates space used raw storage capacity on the cluster
Available legend indicates the available raw storage capacity on the cluster.

Used Capacity Breakdown card

This card shows the actual amount of non-replicated data stored in the cluster and its distribution. You can choose between Projects, Storage Classes, and Pods from the drop-down menu on the card. These options are for filtering the data shown in the graph. The graph displays the used capacity for only the top five entities, based on usage. The aggregate usage of the remaining entities is displayed as Other.

Option	Display
Projects	The aggregated capacity of each project which is using the Fusion Data Foundation and how much is being used.
Storage Classes	The aggregate capacity based on Fusion Data Foundation based storage classes.
Pods	All the pods trying to use the PVC backed by Fusion Data Foundation provisioner.

Note: For external mode, see Capacity breakdown card.

Capacity breakdown card

This card is only applicable for external mode clusters. In this card, you can view graphic breakdown of capacity per project, storage classes and pods. You can choose between Projects, Storage Classes, and Pods from the drop-down menu on the card. These options are for filtering the data shown in the graph. The graph displays the used capacity for only the top five entities, based on usage. The aggregate usage of the remaining entities is displayed as Other.

Utilization card

The card shows used capacity, input/output operations per second, latency, throughput, and recovery information for the internal mode cluster.

For external mode, this card shows only the used and requested capacity details for that cluster.

Storage Efficiency card

This card shows the compression ratio that represents a compressible data effectiveness metric inclusive of all compression-enabled pools. It also shows the savings metric that represents the actual disk capacity saved inclusive of all compression-enabled pools and associated replicas.

Activity card

This card shows what activities are happening or have recently happened in the Fusion Data Foundation cluster. The card is separated into two sections:

Ongoing: Displays the progress of ongoing activities related to rebuilding of data resiliency and upgrading of Fusion Data Foundation operator.
Recent Events: Displays the list of events that happened in the openshift-storage namespace.
