ibm-healthcheck-operator

Important: Do not install this operator directly. Only install this operator using the IBM Common Services Operator. For more information about installing this operator and other Common Services operators, see Installer documentation. If you are using this operator as part of an IBM Cloud Pak, see the documentation for that IBM Cloud Pak to learn more about how to install and use the operator service. For more information about IBM Cloud Paks, see IBM Cloud Paks that use Common Services.

You can use the ibm-healthcheck-operator to install the IBM System Healthcheck service. You can use IBM System Healthcheck service to check the service status of the IBM Cloud Paks and IBM Cloud Platform Common Services.

For more information about the available IBM Cloud Platform Common Services, see the IBM Knowledge Center.
