VMWARE DATASTORE REPORTS with PowerShell

VMware Datastore Information in VCenter:

As the Solarwinds does not currently collect VMware Datastore usage information using the VMware API as shown above I created a Windows PowerShell Script to collect these information and write to Solarwinds Database – NetPerfMon. Then build a SQL report in Solarwinds shown below:

Steps:

(1) Create a table to store Datastore Information in Solarwinds Database – NetPerfMon

(2) On the Solarwinds server (or a polling engine), Install VMware vSphere PowerCLI (You can download it from https://my.vmware.com/web/vmware/details?productId=285&downloadGroup=VSP510-PCLI-510)

(3) Create a PowerShell script to get Datastore Information from a Vcenter (not from VM host) and save to Solarwinds Database – NetPerfMon

################### GetDatastoreInfo.ps1 #####################################

##### Add VMWare Snanpin.

if(-not (Get-PSSnapin VMware.VimAutomation.Core -ErrorAction SilentlyContinue))

{

   Add-PSSnapin VMware.VimAutomation.Core 

}

$MB_TO_GB = 1024

$report = @()

$rowValues = @()

##### Get VC connected. ######################

$VCServer = "your-vcener-ip-or-name"

$VCUserName = "vcenter-user-name"

$VCPassword = "vcenter-password"

$VCconnection = Connect-VIServer $VCServer -Protocol https -User $VCUserName -Password $VCPassword -ErrorAction SilentlyContinue

##### Get Datastore Information ##################

$allDataStores = Get-Datastore

foreach ($dStore in $allDataStores) {

     $row = $VCServer + "," + $dStore.Datacenter + "," + $dStore.UID  + "," + $dStore.Name + "," + $dStore.Type + "," + [int]($dStore.CapacityMB/$MB_TO_GB*10)/10.0 + "," + [int]($dStore.FreeSpaceMB/$MB_TO_GB*10)/10.0 + "," + [int](($dStore.FreeSpaceMB/$dStore.CapacityMB)*1000)/10.0 +  "," + [System.DateTime]::Now 

     $report += $row

}

Disconnect-VIServer $VCServer -Confirm:$False -ErrorAction SilentlyContinue

##### Write to NetPerfMon database #########################

### open database connection

$SQLServer = "your-solarwinds-sql-server-name-or-ip" #use Server\Instance for named SQL instances!

$SQLDBName = "NetPerfMon"

$SQLDBUser = "db-username"

$SQLDBPwd = "db-password"

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; user id=$SQLDBUser;password=$SQLDBPwd"

$SqlConnection.Open()

### instet rows

$Sqlcmd = $SqlConnection.CreateCommand()

foreach ($currentRow in $report){

  $rowValues = $currentRow.Split(",")

  $InsertStatement = "INSERT [dbo].[VIM_DatastoreInfo]  VALUES ( "

  $InsertStatement = $InsertStatement + "'" + $rowValues[0] + "','" + $rowValues[1] + "','" + $rowValues[2] + "','" + $rowValues[3] + "','" + $rowValues[4] + "'," +  $rowValues[5] + "," +  $rowValues[6] + "," + $rowValues[7] + ",'" + $rowValues[8] + "')" 

  #### Write-Host $InsertStatement   --- test code

  $Sqlcmd.CommandText = $InsertStatement

  $Sqlcmd.ExecuteNonQuery()

}

$SqlConnection.Close()

(4) Run the PowerShell script as a schedule task

(5)  Create a Solarwinds report

Tested in Solarwins NPM 10.4 & VMware 4 & 5
