VMware Datastore Information in VCenter:
![01.jpg]()
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
![03.jpg]()
(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

##### Write to NetPerfMon database #########################
### open database connection

$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
