Usage
-----
.. code-block:: none

  oci database-management cluster-cache-metric get [OPTIONS]

Required Parameters
--------------------
.. option:: --end-time [text]

The end time of the time range to retrieve the health metrics of a Managed Database in UTC in ISO-8601 format, which is "yyyy-MM-dd'T'hh:mm:ss.sss'Z'".

.. option:: --managed-database-id [text]

The `OCID <https://docs.cloud.oracle.com/Content/General/Concepts/identifiers.htm>`__ of the Managed Database.

.. option:: --start-time [text]

The start time of the time range to retrieve the health metrics of a Managed Database in UTC in ISO-8601 format, which is "yyyy-MM-dd'T'hh:mm:ss.sss'Z'".


Optional Parameters
--------------------
.. option:: --from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The :option:`--generate-full-command-json-input` option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id --> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our "using CLI with advanced JSON options" link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions
