Module netapp_ontap.resources.metrocluster_diagnostics
Copyright © 2021 NetApp Inc. All rights reserved.
Overview
You can use this API to initiate a MetroCluster diagnostics operation and fetch the results of a completed diagnostics operation on a MetroCluster over IP configuration. The GET operation retrieves the results of a completed diagnostics operation for the MetroCluster over IP configuration. The POST request can be used to start a MetroCluster diagnostics operation or set up a schedule for the diagnostics to be run periodically.
Starting a MetroCluster diagnostics operation
A new MetroCluster diagnostics operation can be started by issuing a POST to /cluster/metrocluster/diagnostics. There are no extra parameters required to initiate a diagnostics operation.
Polling the POST job for status of diagnostics operation
After a successful POST /cluster/diagnostics operation is issued, an HTTP status code of 202 (Accepted) is returned along with a job UUID and a link in the body of the response. The POST job continues asynchronously and can be monitored by using the job UUID and the /cluster/jobs API. The "message" field in the response of the GET /cluster/jobs/{uuid} request shows the current step in the job, and the "state" field shows the overall state of the job.
Examples

Classes
class MetroclusterDiagnostics (*args, **kwargs)
-
Allows interaction with MetroclusterDiagnostics objects on the host
Initialize the instance of the resource.
Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:
MyResource(name='foo').name == 'foo'
Args
*args
- Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
**kwargs
- each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.
Ancestors
Methods
def get(self, **kwargs) -> NetAppResponse
-
Retrieves the results of a completed diagnostic operation for the MetroCluster configuration.
Learn more
Fetch the details of the object from the host.
Requires the keys to be set (if any). After returning, new or changed properties from the host will be set on the instance.
Returns
A
NetAppResponse
object containing the details of the HTTP response.Raises
NetAppRestError
: If the API call returned a status code >= 400 def post(self, hydrate: bool = False, poll: bool = True, poll_interval: typing.Union = None, poll_timeout: typing.Union = None, **kwargs) -> NetAppResponse
-
Start a MetroCluster diagnostic operation or set up a schedule for the diagnostics to be run periodically.
Learn more
Send this object to the host as a creation request.
Args
hydrate
- If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of the object.
poll
- If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval
- If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout
- If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
**kwargs
- Any key/value pairs passed will normally be sent as query parameters to the host. If any of these pairs are parameters that are sent as formdata then only parameters of that type will be accepted and all others will be discarded.
Returns
A
NetAppResponse
object containing the details of the HTTP response.Raises
NetAppRestError
: If the API call returned a status code >= 400
