Metrics in the Object dashboard

Learn how to navigate the Object dashboard.

You can navigate to the Object 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 Object tab.

The following metrics are available in the Object dashboard:

Details card

This card shows the following information:

Service Name: The Multicloud Object Gateway (MCG) service name.
System Name: The Multicloud Object Gateway and RADOS Object Gateway system names. The Multicloud Object Gateway system name is also a hyperlink to the MCG management user interface.
Provider: The name of the provider on which the system runs (for example: AWS, VSphere, None for Baremetal)
Version: Fusion Data Foundation operator version.

Storage Efficiency card

In this card you can view how the MCG optimizes the consumption of the storage backend resources through deduplication and compression and provides you with a calculated efficiency ratio (application data vs logical data) and an estimated savings figure (how many bytes the MCG did not send to the storage provider) based on capacity of bare metal and cloud based storage and egress of cloud based storage.

Buckets card

Buckets are containers maintained by the MCG and RADOS Object Gateway to store data on behalf of the applications. These buckets are created and accessed through object bucket claims (OBCs). A specific policy can be applied to bucket to customize data placement, data spill-over, data resiliency, capacity quotas, and so on.

In this card, information about object buckets (OB) and object bucket claims (OBCs) is shown separately. OB includes all the buckets that are created using S3 or the user interface(UI) and OBC includes all the buckets created using YAMLs or the command line interface (CLI). The number displayed on the left of the bucket type is the total count of OBs or OBCs. The number displayed on the right shows the error count and is visible only when the error count is greater than zero. You can click on the number to see the list of buckets that has the warning or error status.

Resource Providers card

This card displays a list of all Multicloud Object Gateway and RADOS Object Gateway resources that are currently in use. Those resources are used to store data according to the buckets policies and can be a cloud-based resource or a bare metal resource.

Status card

This card shows whether the system and its services are running without any issues. When the system is in a warning or error state, the alerts section is shown and the relevant alerts are displayed there. Click the alert links beside each alert for more information about the issue. For information about health checks, see Cluster health.

If multiple object storage services are available in the cluster, click the service type (such as Object Service or Data Resiliency) to see the state of the individual services.

Data resiliency in the status card indicates if there is any resiliency issue regarding the data stored through the Multicloud Object Gateway and RADOS Object Gateway.

Capacity breakdown card

In this card you can visualize how applications consume the object storage through the Multicloud Object Gateway and RADOS Object Gateway. You can use the Service Type drop-down to view the capacity breakdown for the Multicloud Gateway and Object Gateway separately. When viewing the Multicloud Object Gateway, you can use the Break By drop-down to filter the results in the graph by either Projects or Bucket Class.

Performance card

In this card, you can view the performance of the Multicloud Object Gateway or RADOS Object Gateway. Use the Service Type drop-down to choose which you would like to view.

For Multicloud Object Gateway accounts, you can view the I/O operations and logical used capacity. For providers, you can view I/O operation, physical and logical usage, and egress.

Table 1 explains the different metrics that you can view based on your selection from the drop-down menus on the card.

Table 1. Indicators for Multicloud Object Gateway
Consumer types	Metrics	Chart display
Accounts	I/O operations	Displays read and write I/O operations for the top five consumers. The total reads and writes of all the consumers is displayed at the bottom. This information helps you monitor the throughput demand (IOPS) per application or account.
Accounts	Logical Used Capacity	Displays total logical usage of each account for the top five consumers. This helps you monitor the throughput demand per application or account.
Providers	I/O operations	Displays the count of I/O operations generated by the MCG when accessing the storage backend hosted by the provider. This helps you understand the traffic in the cloud so that you can improve resource allocation according to the I/O pattern, thereby optimizing the cost.
Providers	Physical vs Logical usage	Displays the data consumption in the system by comparing the physical usage with the logical usage per provider. This helps you control the storage resources and devise a placement strategy in line with your usage characteristics and your performance requirements while potentially optimizing your costs.
Providers	Egress	The amount of data the MCG retrieves from each provider (read bandwidth originated with the applications). This helps you understand the traffic in the cloud to improve resource allocation according to the egress pattern, thereby optimizing the cost.

For the RADOS Object Gateway, you can use the Metric drop-down to view the Latency or Bandwidth.

Latency: Provides a visual indication of the average GET/PUT latency imbalance across RADOS Object Gateway instances.
Bandwidth: Provides a visual indication of the sum of GET/PUT bandwidth across RADOS Object Gateway instances.

Activity card

This card displays 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.
