Service Health Details

The dashboard reports on:

1. Health of specific Private Cloud Director services. This is under the Service Health tab. Following services are covered under this:

   1. Compute Service

   2. Block Storage Service

   3. Image Library Service

   4. Networking Service

2. Health of individual hosts running in your Private Cloud Director setup. This is under Host Health tab.

Compute Service Health

Compute service health is calculated using the following logic:

• If => 50% of all host with hypervisor role assigned are in unhealthy state, the service is reported to be unhealthy

• If > 25% but < 50% of all hosts with hypervisor role assigned are in unhealthy state, the service is reported to be in warning state

• If <= 25% of all hosts with hypervisor role assigned are in offline state, the service is reported to be in healthy state

Individual host level health status is calculated using the following logic:

• If the Host States value is not ok then unhealthy.

• If the host state value is ok, then:

  • If the host is in maintenance mode, then warning, else

  • If Compute Service health status for this host is ok, then healthy

  • Else unhealthy

The compute service health status value at the host level is gathered using this command:

Bash

pcdctl compute service list --service nova-compute

Image Library Service Health

Image library service health value may have one of the following values:

• NetworkError - If the Private Cloud Director has trouble connecting with the Image Library service, this error value is reported.

• Unhealthy - If the Private Cloud Director management plane can connect with the Image Library service, but the service API is unresponsive, this status value is reported.

• Healthy - If the Private Cloud Director is able to connect with the Image Library Service, and the service API is responding, the service health is reported as Healthy.

Block Storage Service Health

Block storage service health value may have one of the following values:

• Unhealthy - If the block storage service health status for the host is unhealthy, then this value is reported

• Healthy - If the block storage service health status for the host is healthy, then this value is reported

Network Service Health

Network service health value may have one of the following values:

• Unhealthy - If the network service health status for the host is unhealthy, then this value is reported

• Healthy - If the network service health status for the host is healthy, then this value is reported
