第 3 章 Metrics
3.1. Metrics in the Block and File dashboard
You can navigate to the Block and File dashboard in the OpenShift Web Console as follows:
-
Click Storage
Data Foundation. - In the Status card of the Overview tab, click Storage System and then click the storage system link from the pop up that appears.
- Click the Block and File tab.
The following cards on the Block and File dashboard provide 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, for example,
AWS,VSphere,Nonefor Bare metal. - Mode (deployment mode as either Internal or External)
- OpenShift Data Foundation operator version
- In-transit encryption (shows whether the encryption is enabled or disabled)
- Storage Efficiency card
- This card shows the compression ratio that represents a compressible data effectiveness metric, which includes all the compression-enabled pools. This card also shows the savings metric that represents the actual disk capacity saved, which includes all the compression-enabled pools and associated replicas.
- Inventory card
- The Inventory card shows the total number of active nodes, disks, pools, storage classes, PVCs, and deployments backed by OpenShift Data Foundation provisioner.
For external mode, the number of nodes will be 0 by default as there are no dedicated nodes for OpenShift 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.
For external mode, Data Resiliency and alerts are not displayed
- Raw Capacity card
This card shows the total raw storage capacity, which includes replication on the cluster.
-
Usedlegend indicates space used raw storage capacity on the cluster -
Availablelegend indicates the available raw storage capacity on the cluster
-
This card is not applicable for external mode clusters.
- Requested Capacity
This card shows the actual amount of non-replicated data stored in the cluster and its distribution. You can choose between Projects, Storage Classes, Pods, and Peristent Volume Claims from the drop-down list on the top of the card. You need to select a namespace for the Persistent Volume Claims option. These options are for filtering the data shown in the graph. The graph displays the requested capacity for only the top five entities based on usage. The aggregate requested capacity of the remaining entities is displayed as Other.
Option Display Projects
The aggregated capacity of each project which is using the OpenShift Data Foundation and how much is being used.
Storage Classes
The aggregate capacity which is based on the OpenShift Data Foundation based storage classes.
Pods
All the pods that are trying to use the PVC that are backed by OpenShift Data Foundation provisioner.
PVCs
All the PVCs in the namespace that you selected from the dropdown list and that are mounted on to an active pod. PVCs that are not attached to pods are not included.
For external mode, see the Capacity breakdown card.
- Capacity breakdown card
-
This card is only applicable for external mode clusters. In this card, you can view a 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 top of 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.
- Activity card
This card shows the current and the past activities of the OpenShift 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 OpenShift Data Foundation operator.
-
Recent Events: Displays the list of events that happened in the
openshift-storagenamespace.
