Sample script pulling the FCS error rate from a CVP instance. If no rate is available, then there was never an FCS error on that device/interface
The get_token.py script can be used to generate an auth token and crt file, for access to on-premises CVP. Service account tokens can also be used. For more details, see here
There are 2 options for the client call wth the query - client.get() and client.subscribe(). Get is analogous to an SNMP GET, it is a once off retrieval of data. Subscribe keeps the connection open, and provides an update/notification if there are any changes.
Wildcard() allows for multiple entities to be subscribed to. In this example we are querying all devices ( line 33 ) and than all interfaces ( line 37 )
Please see the CloudVision Python libraries for more examples.
