Error Updating Properties and Custom Properties of Nodes

Which properties are you updating when you receive this error?

There is a bug in the product and update of some properties (e.g. community) throw similar exception.

I am trying to update these Default and Custom Properties.

Default:

EngineID

Caption

Location

ObjectSubType

SNMPVersion

Custom:

ServerFunction

Environment

DomainName

Thanks.

I am also getting the following error when calling new-swisobject:

New-SwisObject : Object reference not set to an instance of an object.

At line:1 char:28

+ ... ewNodeUri = New-SwisObject $swis -EntityType "Orion.Nodes" -Propertie ...

+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (:) [New-SwisObject], NullReferenceException

    + FullyQualifiedErrorId : System.NullReferenceException,SwisPowerShell.NewSwisObject

Thanks.

Just a guess but try updating only the Custom ones and not the Default ones and see if you get an error. Some of the custom ones appear to be 'locked down' in custom property editor. Such as Location which is typically derived from SNMP.

Unfortunately update of properties

ObjectSubType

SNMPVersion

leads to error, this is product bug and we track it under ticket CORE-6263.

Until the bug will be fixed, it is not possible to update these properties using SDK API :-(.

Try to remove properties ObjectSubType and SNMPVersion from update call, you should be able to update other properties (caption, location, custom properties).

Please be aware that you need to use special URI when updating custom properties.

Example:

swis.update('swis://localhost/Orion/Orion.Nodes/NodeID=18/CustomProperties', Environment='PROD')

Which properties are you setting for new node?

Could you please paste important part of your script here?

FYI I am importing Props from a .csv file and running a for each where

foreach($node in $csv)

{

$newNodeProps = @{

                nodeID = $node.nodeID;

               #NODEID was the issue

                IPAddress = $node.IP; #Imported Ip Address from CSV file.

                EngineID = $node.EngineID; #Default EngineID

                Caption = $node.Caption; #Imported Caption from CSV file.

                #Location = $node.Location;

                # SNMP v2 specific

                ObjectSubType = $node.ObjectSubType;

                SNMPVersion = $node.SNMPVersion;

     $NewNodeUri = New-SwisObject $swis -EntityType "Orion.Nodes" -Properties $NewNodeProps

      $nodeProps = Get-SwisObject $swis -Uri $newNodeUri

                # register specific pollers for the node

                Write-Verbose 'Registering Pollers'

                $poller = @{

                NetObject="N:"+$nodeProps["NodeID"];

                NetObjectType="N";

                NetObjectID=$nodeProps["NodeID"];

                }#$poller

                # Status

                $poller["PollerType"]="N.Status.ICMP.Native";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

                # Response time

                $poller["PollerType"]="N.ResponseTime.ICMP.Native";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

                # Details

                $poller["PollerType"]="N.Details.SNMP.Generic";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

                # Uptime

                $poller["PollerType"]="N.Uptime.SNMP.Generic";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

                # CPU

                $poller["PollerType"]="N.Cpu.SNMP.CiscoGen3";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

                # Memory

                $poller["PollerType"]="N.Memory.SNMP.CiscoGen3";

                $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

               $customProps = @{

                    ServerFunction = $node.ServerFunction;

                    Environment = $node.EVNT;

                    DomainName = $node.DomainName;

               Get-SwisData $swis "SELECT Nodes.CustomProperties.Uri FROM Orion.Nodes where IP = @IP" @{IP = $node.IP} `

                    |Set-SwisObject $swis  -Properties $customProps -erroraction continue

}#foreach($node in $csv)

I've spent some time working on something similar and although this doesn't include what you mentioned in your example you can probably take this and run with it. This script applies to custom properties, although I suppose you could tweak this to apply to generic properties. I have provided two different ways of doing this, so look at the script, choose which method best fits your needs and edit the script accordingly.

#Intialize Swis-Snapin

Add-PSSNapin SwisSnapin 

# Connect to SWIS

$hostname = "Insert Orion IP"

$username = "Insert Username"

$password = "Insert Password" or you can use get-content Insert Path to Password Text Document | convertto-securestring 

$cred = New-Object -typename System.Management.Automation.PSCredential -argumentlist $username, $password 

$swis = Connect-Swis -host $hostname -cred $cred

# This Next Section is Optional if You are Using Traditional SELECT Statements

$filename = "Insert Path to Txt Doc with IP Addresses"

$ips = Get-Content $filename

# prepare a custom property value

$customProps = @{ 

  Example 1=" "

  Example 2=" "

} 

# Option 1 - If you are using the get-content $filename method

$uris = Get-SwisData $swis "SELECT Nodes.CustomProperties.Uri FROM Orion.Nodes WHERE IP IN @ips" @{ ips = $ips }

$uris | Set-SwisObject $swis -Properties $customProps

# Option 2 - If you are using a traditional SELECT statement

$uris = Get-SwisData $swis "SELECT Nodes.CustomProperties.Uri FROM Orion.Nodes WHERE IP_Address LIKE 'Insert IP Address(s) Here'"

$uris | Set-SwisObject $swis -Properties $customProps

Thanks!

That solved the issue.

I can see two bugs in script:

- nodeId should not be set when node is created, nodeId value will be set by Orion

- setting of custom properties should be done in following way: Set-SwisObject $swis  -Uri ($NewNodeUri + "/CustomProperties") -Properties $customProps
