**Table 7** AddonInstanceStatus
Parameter	Type	Description
status	String	Add-on instance status. Options: running: All of the add-on instances are running. This specifies that the add-on runs properly. abnormal: The add-on instances are abnormal and the add-on cannot be used.

In this case, uninstall the add-on and then reinstall it. upgrading: The add-on is being upgraded. upgradeFailed: Upgrading the add-on failed. In this case, upgrade the add-on again or uninstall the add-on and reinstall it. deleting: The add-on is being deleted. deleteFailed: Deleting the add-on failed. In this case, uninstall the add-on again. deleteSuccess: Deleting the add-on succeeded. available: Only some instances of the add-on are running. This specifies that some functions of the add-on are available. rollbacking: The add-on is being rolled back. rollbackFailed: Rolling back the add-on failed. In this case, roll back the add-on again or uninstall the add-on and reinstall it. unknown: The add-on chart instance does not exist.
Reason	String	Cause of the add-on installation failure.
message	String	Installation error details.
