REST API NODE CREATION PASSWORDISKEY SETTINGS

levilippincott

Hello, we have a requirement to be able to push Nodes into the system via REST API. We are running 12.2.

I'm running a POST command against this URL: https://<myserver>:17778/SolarWinds/InformationService/v3/Json/Create/Orion.Nodes

Here is the Body:

{
     "ObjectSubType": "SNMP",
     "IPAddress": "XXX.XXX.XXX.XXX",
     "IPAddressType": "IPv4",
     "DynamicIP": false,
     "NodeDescription": "",
     "Description": "Cisco Catalyst 38xx stack",
     "SysName": "<sysname>",
     "IOSImage": "",
     "IOSVersion": "",
     "Vendor": "Cisco",
     "Icon": "9.gif               ",
     "Location": <location>"",
     "Contact": "<contact>",
     "CMTS": "N",
     "SNMPVersion": 3,
     "EngineID": 1,
     "Status": 1,
     "NodeName": "<nodename>",
     "Allow64BitCounters": true,
     "Community": "",
     "EntityType": "Orion.Nodes",
     "UnManaged": false,
     "SNMPV3Username": "<user>",
     "SNMPV3AuthMethod": "SHA1",
     "SNMPV3PrivKey": "<privkey>",
     "SNMPV3AuthKey": "<authkey>",
     "SNMPV3PrivMethod": "AES128",
     "RWSNMPV3Username": "<user>",
     "RWSNMPV3PrivMethod": "AES128",
     "RWSNMPV3PrivKey": <privkey>"",
     "RWSNMPV3AuthMethod": "SHA1",
     "RWSNMPV3AuthKey": ""authkey>",
     "SNMPv3PrivKeyIsPwd": "true",
     "SNMPv3AuthKeyIsPwd": "true",
     "RWSNMPV3PrivKeyIsPwd": "true",
     "RWSNMPV3AuthKeyIsPwd": "true"
}

When we try to run that we get the following response.

{
    "Message": "Specified cast is not valid.",
    "ExceptionType": "System.InvalidCastException",
    "FullException": "System.InvalidCastException: Specified cast is not valid.\r\n  
          at SolarWinds.Data.Providers.Orion.Helpers.SnmpV3CredentialsHelper.UpdateNodesSnmpV3Credentials(Int32[] nodeIds, IDictionary`2 columnsToUpdate)\r\n  
          at SolarWinds.Data.Providers.Orion.CrudHandlers.NodeCrudHandler.Create(IEnumerable`1 infos, Func`2 baseCall)\r\n  
          at SolarWinds.InformationService.Addons.DataProvider.d__62.MoveNext()\r\n  
          at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection)\r\n  
          at SolarWinds.InformationService.Core.CrudProcessor.d__21.MoveNext()\r\n  
          at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)\r\n  
          at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)\r\n  
          at SolarWinds.InformationService.Core.CrudProcessor.d__18.MoveNext()\r\n  
          at System.Linq.Enumerable.First[TSource](IEnumerable`1 source)\r\n  
          at SolarWinds.InformationService.Core.CrudProcessor.Create(String entityType, IDictionary`2 properties, IQueryExecutionContext context)\r\n  
          at SolarWinds.InformationService.Core.InformationService.Create(String entityType, IDictionary`2 properties)"
}

If we take out the "SNMPv3PrivKeyIsPwd": "true", "SNMPv3AuthKeyIsPwd": "true", "RWSNMPV3PrivKeyIsPwd": "true", & "RWSNMPV3AuthKeyIsPwd": "true" the node will create successfully but all the Key fields are checked by default and we do not want that.

If we try to run an update action to SNMPv3Credentials form using a post action to this URL: https://<myserver>:17778/SolarWinds/InformationService/v3/Json/swis://<myserver>/Orion/Orion.Nodes/NodeID=154/SNMPv3Credentials

With this Body:

{
"AuthenticationKeyIsPassword": "true",
"PrivacyKeyIsPassword": "true",
"RWAuthenticationKeyIsPassword": "true",
"RWPrivacyKeyIsPassword": "true"
}

Then we get this error:

{
    "Message": "Specified cast is not valid.",
    "ExceptionType": "System.InvalidCastException",
    "FullException": "System.InvalidCastException: Specified cast is not valid.\r\n  
          at SolarWinds.Data.Providers.Orion.Helpers.SnmpV3CredentialsHelper.UpdateNodesSnmpV3Credentials(Int32[] nodeIds, IDictionary`2 columnsToUpdate)\r\n  
          at SolarWinds.Data.Providers.Orion.OrionDataProvider.Update(IStorageElement storage, IDictionary`2[] keyColumnsList, IDictionary`2 columnsToUpdate)\r\n  
          at SolarWinds.InformationService.Core.CrudProcessor.UpdateInternal(Boolean bulkMode, SwisUriResolver uriResolver, IDictionary`2 propertiesToUpdate, IQueryExecutionContext context)\r\n  
          at SolarWinds.InformationService.Core.CrudProcessor.Update(SwisUri uri, IDictionary`2 propertiesToUpdate, IQueryExecutionContext context)\r\n  
          at SolarWinds.InformationService.Core.InformationService.Update(String uri, IDictionary`2 propertiesToUpdate)"
}

If I try to modify different fields on that SNMPv3Credentials form, like PrivacyMethod or RWPrivacyMethod on their own then those will change fine.

I assume I'm missing something simple somewhere but maybe I'm totally wrong. Any ideas?

I wanted to provide everyone an update in case anyone else is experiencing this issue as well. This was a total syntax user error.

My "true" was incorrect and it should have been just true.

So instead of being this:

"SNMPv3PrivKeyIsPwd": "true",  
"SNMPv3AuthKeyIsPwd": "true",  
"RWSNMPV3PrivKeyIsPwd": "true",  
"RWSNMPV3AuthKeyIsPwd": "true"

It should have been this:

"SNMPv3PrivKeyIsPwd": true,
"SNMPv3AuthKeyIsPwd": true,
"RWSNMPV3PrivKeyIsPwd": true,
"RWSNMPV3AuthKeyIsPwd": true

This fixed it on both scenarios I provided above, so I can send it through all as one action on the Node creation without having to run a second update action.
