Issues discovering Windows node with Solarwinds API (python)

alex.pop

Hi everyone,

I'm having issues onboarding a Windows node (WMI). I've had no issues with Linux/ snmp nodes, but the former fails without helpful error messages.

Code example and errors below:

    def discover_windows_host(self,target_node_ip,credentials_id,EngineID):

        corePluginContext = {

        'BulkList': [{'Address': target_node_ip}],

        'Credentials': [

            {

                'CredentialID': credentials_id,  #WMI credentials ID

                'Order': 1

            }

        ],

        'WmiRetriesCount': 1,

        'WmiRetryIntervalMiliseconds': 1000

        }

        print(corePluginContext)

        corePluginConfig = self.swis.invoke('Orion.Discovery', 'CreateCorePluginConfiguration', corePluginContext)

        discoveryProfile = {

            'Name': 'discovery_host',

            'EngineID': EngineID,

            'JobTimeoutSeconds': 3600,

            'SearchTimeoutMiliseconds': 5000,

            'SnmpTimeoutMiliseconds': 5000,

            'SnmpRetries': 2,

            'RepeatIntervalMiliseconds': 1800,

            'HopCount': 0,

            'DisableIcmp': False,

            'AllowDuplicateNodes': False,

            'IsAutoImport': True,

            'IsHidden': True,

            'PluginConfigurations': [{'PluginConfigurationItem': corePluginConfig}]

        }

        print(discoveryProfile)

        discoveryid = self.swis.invoke('Orion.Discovery', 'StartDiscovery', discoveryProfile)

        return discoveryid

Any input is appreciated as I'm out of ideas.

Thanks so much!!

I don't have the solution to your specific script, but I will say that I use exactly the same powershell script for all nodes, wmi or snmp, with no changes needed.  The error it's kicking back is that it can't make sense of one of the parameters you are passing, but I don't use python enough to see the typo or whatever that may be giving you the headache.
