Fleet Management

This topic explains how SRE users of Tanzu Data Hub can use a fleet management dashboard to view the current status of database instances, and perform bulk upgrades on fleets of database instances across organizations.

The Fleet Management pane in Tanzu Data Hub has two tabs:

• Overview is a read-only dashboard that shows database instance usage, current status, health, alerts and other information across organizations.
• Upgrade supports upgrading Helm versions used by data planes, database service versions, and certificates.

These functions are described in the sections below.

Overview Dashboard

The Overview dashboard shows a high-level view of database service status and usage across all organizations and within specific organizations.

• The Organization Stats section at the top shows statistics across all organizations:

  • Organization and data plane counts
  • Data plane health status
    • Healthy status means that the data plane is in a Ready state.
  • Service instance counts for each service.

• The Shared data plane Capacity section lists each shared data plane with Memory usage, CPU usage, and service instance counts.

  • Memory and CPU usage show as percentages; hover over to see total, used, and remaining numbers in GB and vCPU units.

  

• The Organization Details section shows statistics for the organization selected at the top.

  • Dedicated Dataplane for < organization name > shows usage for dedicated data planes for the organization, with the same fields as Shared data plane capacity above.
  • Graphs show instance counts and health for each service.

  

Upgrade Operations

Tanzu Data Hub supports upgrading three things via its GUI:

• The version of the service run by an instance, such as the MySQL version.
• The Helm version in data planes that use Helm service engine, such as for managing Redis instances.
• Certificates used by service instances and shows their upcoming expiration dates.
  • Upgrading a certificate means rotating it.

These correspond to the three sub-tabs under the Upgrade tab in the Fleet Management pane accessible to SRE users: Services, Data Planes, and Certificates.

Admin users can upgrade service versions and certificates for a database instance from Instances > Instance details pane:
