Invoke-SwisVerb : Verb Orion.AlertSuppression.SuppressAlerts cannot unpackage parameter 0 of type System.String

Import-Module SwisPowerShell

$OrionServer = 'localhost'
$cred = Get-Credential

$swis = Connect-Swis -Hostname $OrionServer -Credential $cred

$server = 'my-server'
$query = "SELECT Uri FROM Orion.Nodes WHERE SysName LIKE '" + "$server" + "%'"
$entityUris = Get-SwisData $swis $query
$entityUris = $entityUris |% {[string]$_}

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts @($entityUris)

Trying to mute alerts on an object, using the code above and always receive the following error message:

Invoke-SwisVerb : Verb Orion.AlertSuppression.SuppressAlerts cannot unpackage parameter 0 of type System.String[]

Try sending the $entityUris by itself and not wrapping it as an array so:

.... SuppressAlerts $entityUris

Hi,

It doesn't seem to matter how I pass the parameter, the following all fail:

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts "swis://myserver.xyz/Orion/Orion.Nodes/NodeID=29"
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts @($entityUris)
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts (@($entityUris))
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts $entityUris

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts $entityUris

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts (@($entityUris))

Ahh I should have caught that. The verb needs 3 paramaters in the array.

1) entity uri

2) start time Utc

3) end time Utc or $null .. not providing this param may be the same as providing $null with the end result of an indefinite mute

So this should work:

$now = (Get-Date)::UtcNow

$2hoursFromNow = $now.AddHours(2)

.... SuppressAlerts @($entityUris, $now, $2hoursFromNow)

Hi,

Thanks for looking into this, but I am still getting the same error. See logs:

Hi - do you have any more ideas on this?

raymondakrawi

I keep getting an error when trying to use the invoke-swisverb

Invoke-SwisVerb : Access to Orion.AlertSuppression.SuppressAlerts verb denied.

Has anyone else seen this?

bobmarley

This works on mine, 2023.1 and 3.1.0.343 SwisPowerShell. I wrote it while we were on 2020.2.4 so it was working on that version as well.

Take a look and compare.

cls
Import-Module SwisPowerShell
$swis = Connect-Swis -host MyHost@bobmarley.org -UserName BobMarley -Password LetsGet2getherItWillBeAllRight
#$swis = Connect-Swis -host MyHost@bobmarley.org -trusted
$entityUris = Get-SwisData $swis "SELECT Uri FROM Orion.Nodes WHERE SysName LIKE'MYSERVERNAME'"
$entityUris = @( $entityUris |% {[string]$_} )
$now =[DateTime]::Now
$later =$now.AddMinutes(5)
Write-host "Muting Node from time in UTC $now until $later"
Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts @($entityUris, $now, $later ) | Out-Null

raymondakrawi

I still get the invoke-swis access to orion verb error.

I tried it once like this.

Invoke-SwisVerb $swis Orion.AlertSuppression SuppressAlerts @($entityUris, $now, $later ) | Out-Null

I also tried adding the parameter names before the variables.

Invoke-SwisVerb -SwisConnection $swis -EntityName Orion.AlertSuppression -Verb SuppressAlerts -Arguments @($entityUris, $now, $later ) | Out-Null

Invoke-SwisVerb : Access to Orion.AlertSuppression.SuppressAlerts verb denied.

Did you try changing these values so they match your environment and run this script? This one worked in my environment.

Vinx

Can you verify if the account you use to create swisconnection have enought right to mute/unmute object ?

nodes = Get-SwisData $swis -Query "SELECT Uri FROM Orion.Nodes WHERE SysName LIKE 'MYSERVERNAME'"

foreach ($Uri in $nodes) {
Invoke-SwisVerb $swis -EntityName Orion.AlertSuppression -Verb SuppressAlerts -Arguments @( [string[]] $Uri, (Get-Date), (Get-Date).AddHours((99)))
}
