 Description   

Would be useful to have functionality where WMI query could be converted to JSON that can be supplied for LLD. The item syntax could be the same as for wmi.get[].

Currently the work around is to use system.run or UserParameters utilizing powershell, but that requires at least Windows 2012 or Windows Management Framework with ConvertTo-Json command and You also have to convert all property names before piping array of hashes to ConvertTo-Json. Additionally this creates administrative overhead for distributing helper scripts to agents.

snip from PS code to convert object property names to LLD macros
        $obj | Get-Member | % {
            $PropertyName=$_.Name
            $Value=$obj.$PropertyName
            $HashName="{#" + $PropertyName.ToUpper() + "}"
            if ($_.MemberType -ne "Method" -and $_.MemberType -ne "ScriptMethod" ) {
                $hash.Add($HashName, $Value)
                if ($PropertyName -like "*Time") {
                    if (($obj | Get-Member -MemberType "ScriptMethod" -Name ConvertToDateTime) -ne $null) {
                        Write-Debug "Converting $PropertyName($Value) to unix timestamp"
                        $hash[$HashName]=$($obj.ConvertToDateTime($Value)) | ConvertTo-UnixTimestamp
                    }
                }
            }
        }

It is very, very useful feature for Windows system monitoring.
Nice, if it will supported by zabbix agent for Windows.
I use LLD together with WMI ever and everywhere in Windows:
for hard drive discovery, for service discovery, for shares discovery, for printers discovery, moreover, for MSSQL database discovery.
But, I use wmic whith special format file, which converts result of WMI query to LLD format.

Example:
Windows service discovery
Key: system.run[{$LLD.WMI.SERVICES}]
Macro
{$LLD.WMI.SERVICES}
Value
wmic.exe /output:"%TEMP%\lld-wmi-srv.json" service where startmode="Auto" get displayname,name /format:"%ProgramFiles%\Zabbix\usr\xsl\lld.xsl" & type "%TEMP%\lld-wmi-srv.json" & del "%TEMP%\lld-wmi-srv.json"

I use temp file for output, because wmic works wrong with UTF8 in console.
File lld.xsl attached.

Hi, @Evgeny. 

Is it possible that you attach your lld-wmi-srv.json? Just for I get the complete idea of your solution.
