How to Change multiple Node Hostname

To do it via powershell use this OrionSDK/Samples/PowerShell/Update.Captions.ps1 at master · solarwinds/OrionSDK · GitHub

Also see this for doing it using SQL (+) Bulk Node Name/Caption Change - Forum - Network Performance Monitor (NPM) - THWACK (solarwinds.com)

You could use a custom property or you can load a CSV.

# Build Connection to SWIS - SolarWinds Platform
$SwisHost = <host> # Connection to host $swisConnection = Connect-Swis -Hostname $SwisHost -Certificate # The actual SWIS query $Query = "SELECT N.Caption, N.CustomProperties._Nickname AS NickName, N.IP_Address, N.Uri FROM Orion.Nodes N WHERE N.Caption != N.CustomProperties._Nickname;" # <> N.CustomProperties._NicknameNS $nodes = Get-SwisData -SwisConnection $swisConnection -Query $query

$nodes |
Foreach-Object {
Write-Output "Renaming node $($_.IP_Address), $($_.Caption) to $($_.NickName)"

if($($_.NickName) -like 'NotAvailable') {
Set-SwisObject -SwisConnection $swisConnection -Uri $_.URI -Properties @{ Caption=$($_.IP_Address) }}

# uncomment the lines below if you're seeing the output you expect above
# else {
# Set-SwisObject -SwisConnection $swisConnection -Uri $_.URI -Properties @{ Caption=$($_.NickName) }
}
}

OR

# Build Connection to SWIS - SolarWinds Platform
$SwisHost = <hostname>
# $SwisCreds = Get-Credential -Message "Enter the username/password for '$SwisHost'"
#$SwisConnection = Connect-Swis -Hostname $SwisHost -Credential $SwisCreds
$SwisConnection = Connect-Swis -Hostname $SwisHost -Username <username> -Password <Password>

Write-Host "Reading data from E:\WIP\inventory.csv"
$csv = Import-Csv "E:\WIP\inventory.csv" -Delimiter ';'

$csv | ForEach-Object {

$Caption = $_.Nickname
$IP_Address = $_.IPAddress

$query = "

SELECT Nodes.Caption, Nodes.URI FROM Orion.Nodes Where IPAddress Like '$IP_Address'


"
$nodes = Get-SwisData -SwisConnection $swisConnection -Query $query

foreach ($node in $nodes) {

$newName = $Caption

# skip over this node if it already has the right name
if ($node.Caption -ceq $newName) {
continue
}

Write-Output "Renaming node $IP_Address, $($node.Caption) to $newName"

# uncomment the line below if you're seeing the output you expect above
# Set-SwisObject -SwisConnection $swisConnection -Uri $node.URI -Properties @{ "Caption" = $newName }
}



}

Thank you so much

i make this on Database using this query 

UPDATE nodesdata SET Caption = 'NODE NAME' WHERE IP_Address = '172.60.4.226';

Thank you Giovana. But i am looking for bulk update. 

With ICMP only, we are limited in discovering what the name of the device is, unlike SNMP/WMI/Agent, where we can ask each node for there hostname/system name. ICMP by default will attempt to use reverse DNS to populate a name, if it does not have a DNS entry, then the IP Address will be used.

So the options are (no particular order):
1) Leverage a spreadsheet with the names and use the API as outlined by ldelt 

2) Create a reverse DNS entry for each node.

3) Manually update each node in SolarWinds with a name.
