List databases health with SQL SMO

 

"Get-Databases" function creates a custom "view" of some database properties on the specified SQL server.

 

function Get-SQLDatabases{
    param(
        [string]$server=$(throw "Please specify SQL server name.")
    )

    [void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
    $smo = new-object Microsoft.SqlServer.Management.Smo.Server $server
    $count=0;

    $smo.databases | foreach {
        $db = $smo.databases[$_.name];
        $obj = new-object psobject;
        add-member -inp $obj NoteProperty "#" ($count+1);
        add-member -inp $obj NoteProperty "Server" ([string][regex]::replace($db.Parent,"\[|\]","")).toupper();
        add-member -inp $obj NoteProperty "DB Name" $db.Name;
        add-member -inp $obj NoteProperty "ID" $db.id;
        add-member -inp $obj NoteProperty "Size(MB)" $db.size.tostring("N2");
        add-member -inp $obj NoteProperty "Free(MB)" ($db.SpaceAvailable/1024).tostring("N2") ;
        add-member -inp $obj NoteProperty "Status" $db.Status;
        add-member -inp $obj NoteProperty "Last Backup" $db.LastBackupDate;
        add-member -inp $obj NoteProperty "SystemDB" $db.IsSystemObject;
        $obj;
        $count++
    }
}

I had better luck with replacing [void] on line 6 with a pipe to out-null. Otherwise for some weird reason the GAC object was added to the output so I had an array with two objects, an Assembly object and a PSCustomObject, the latter actually containing the collection of databases.
