Generate Hardware Inventory for Simulated Client with System Center 2012 Configuration Manager Client SDK

  • Article

My colleague Adam has a better series of samples of the Client SDK. You can check these blogs here: https://blogs.msdn.com/b/ameltzer/archive/tags/sdk/.

 

In this blog: https://blogs.msdn.com/b/minfangl/archive/2012/04/25/step-by-step-on-how-to-create-a-fake-client-using-system-center-2012-configuration-manager-client-sdk.aspx, I have shown how to simulate a client in System Center 2012 Configuration Manager with Client SDK. Now I will give you the code sample to create hardware inventory for the simulated client.

Send a hardware inventory message is pretty much like send an DDR (Data Discovery Record) message. Let’s first revise how we generate the DDR message:

//step 1: new a message type

ConfigMgrDataDiscoveryRecordMessage ddrMessage = new ConfigMgrDataDiscoveryRecordMessage();

//step 2: assign the client info and signing cert

ddrMessage.SmsId = clientId;

MessageCertificateX509Volatile certificate = new MessageCertificateX509Volatile(File.ReadAllBytes("c:\\MixedModeTestCert.pfx"), "sccm" /* sample cert password */)

ddrMessage.AddCertificateToMessage(certificate, CertificatePurposes.Signing);

ddrMessage.Settings.HostName = MPHostname;

//step 3: fill in the ddr message

ddrMessage.ADSiteName = "MyADSite";

ddrMessage.SiteCode = "PE1";

ddrMessage.DomainName = DomainName;

ddrMessage.Discover();

ddrMessage.NetBiosName = ClientName;

// step 4: send the message to the MP (it's asynchronous so there won't be a reply)

HttpSender sender = new HttpSender();

ddrMessage.SendMessage(sender);

 

To generate hardware inventory message is similar, you’ll also need the four step:

  1. New a message type
  2. Assign the client info and signing cert
  3. Fill in the hardware inventory message
  4. Send the message to MP.

But for hardware inventory message, you’ll need to fill a lot of information in step 3. So the best practice is to fill in the message with an existing hardware inventory message.

Let’s use the following hardware inventory file:

<?xml version="1.0" encoding="UTF-16"?>

<Report>

  <ReportHeader>

    <Identification>

      <Machine>

        <ClientInstalled>1</ClientInstalled>

        <ClientType>1</ClientType>

        <ClientID>GUID:5F8ACE1E-4DC9-414E-8A82-7EF4C6DBD1B3</ClientID>

        <ClientVersion>5.00.7558.0000</ClientVersion>

        <NetBIOSName>YWEI2</NetBIOSName>

        <CodePage>936</CodePage>

        <SystemDefaultLCID>2052</SystemDefaultLCID>

      </Machine>

    </Identification>

    <ReportDetails>

      <ReportContent>Inventory\x0020Data</ReportContent>

      <ReportType>Full</ReportType>

      <Date>20110327235855.000000-420</Date>

      <Version>1.0</Version>

      <Format>1.1</Format>

    </ReportDetails>

    <InventoryAction ActionType="Predefined">

      <InventoryActionID>{00000000-0000-0000-0000-000000000001}</InventoryActionID>

      <Description>Hardware</Description>

      <InventoryActionLastUpdateTime>20110228151448.000000+000</InventoryActionLastUpdateTime>

    </InventoryAction>

  </ReportHeader>

  <ReportBody>

    <Instance ParentClass="Package" class="Package" Namespace="\\SimulateClient\root\Microsoft\appvirt\client" Content="New">

      <Package>

        <CachedLaunchSize>3604008</CachedLaunchSize>

        <CachedPercentage>100</CachedPercentage>

        <CachedSize>44773376</CachedSize>

        <LaunchSize>3604008</LaunchSize>

        <Name>WnDBG</Name>

        <PackageGUID>2F551D7E-2A50-4889-ABC2-D38CA5F73696</PackageGUID>

        <TotalSize>44773376</TotalSize>

        <Version>4</Version>

        <VersionGUID>533C9337-D762-4917-9A37-ACF6DC03F4DF</VersionGUID>

      </Package>

    </Instance>

  </ReportBody>

</Report>

 

Refer to the below code go generate hardware inventory from this xml sample. You will need to replace the cert file, SMS GUID, etc:

        static void SendFullHinv(Guid ClientUniqueId, string MPHostname, string ClientName, string DomainName)

        {

            //step 1: new a message type

            ConfigMgrHardwareInventoryMessage tHINVMessage = new ConfigMgrHardwareInventoryMessage();

 

            //step 2: assign the client info and signing cert

            tHINVMessage.SmsId = new SmsClientId(ClientUniqueId);

            tHINVMessage.Settings.Security.SigningSmsId = new SmsClientId(ClientUniqueId);

            MessageCertificateX509Volatile certificate = new MessageCertificateX509Volatile(File.ReadAllBytes("c:\\MixedModeTestCert.pfx"), "sccm" /* sample cert password */);

            tHINVMessage.AddCertificateToMessage(certificate,CertificatePurposes.Signing);

 

            //generate report header

            tHINVMessage.Settings.HostName = MPHostname;

            tHINVMessage.NetBiosName = ClientName;

            tHINVMessage.ReportType = InventoryReportType.Full;

            tHINVMessage.DomainName = DomainName;

            tHINVMessage.SiteCode = "PE1";

            tHINVMessage.SmsId = new SmsClientId(ClientUniqueId);

            tHINVMessage.ClientVersion = new ClientVersion("5.00.7711.0000");

 

            //step 3: fill in the hinv message

            tHINVMessage.InventoryReport = new InventoryReport();

            tHINVMessage.InventoryReport.ReportHeader = new InventoryReportHeader();

           

            tHINVMessage.InventoryReport.ReportHeader.Identification = new InventoryIdentification();

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine = new InventoryIdentificationMachine();

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.ClientInstalled = true;

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.ClientType = InventoryClientType.Advanced;

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.ClientId = new InventoryClientId(new SmsClientId(ClientUniqueId));

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.ClientVersion = new ClientVersion("5.00.7711.0000");

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.NetBiosName = ClientName;

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.CodePage = 437;

            tHINVMessage.InventoryReport.ReportHeader.Identification.Machine.LocaleId = 1033;

 

            tHINVMessage.InventoryReport.ReportHeader.Details = new InventoryReportDetails();

            tHINVMessage.InventoryReport.ReportHeader.Details.ReportContent = "Inventory\x0020Data";

            tHINVMessage.InventoryReport.ReportHeader.Details.ReportType = InventoryReportType.Full;

            tHINVMessage.InventoryReport.ReportHeader.Details.ReportTimeString = "20120322145729.366000+000";

            tHINVMessage.InventoryReport.ReportHeader.Details.Version = "2.0";

            tHINVMessage.InventoryReport.ReportHeader.Details.Format = "1.0";

 

            tHINVMessage.InventoryReport.ReportBody = new InventoryReportBody();

 

            GenerateHinvInstancesFromXml("c:\\Win7A.xml", tHINVMessage);

            tHINVMessage.InventoryReport = tHINVMessage.BuildInventoryMessage(tHINVMessage.HardwareInventoryInstances, false);

            tHINVMessage.InventoryReport.ReportHeader.Action = new InventoryActionHardwareInventory();

            tHINVMessage.InventoryReport.ReportHeader.Action.LastUpdateTime = new DateTime(2012,5,18);

           

           

            // step 4: send the message to the MP (it's asynchronous so there won't be a reply)

            HttpSender sender = new HttpSender();

            tHINVMessage.SendMessage(sender);

        }

 

        static void GenerateHinvInstancesFromXml(string fullfilepath, ConfigMgrHardwareInventoryMessage tHINVMessage)

        {

            XmlDocument xdoc = new XmlDocument();

            xdoc.Load(fullfilepath);

            XmlElement root = xdoc.DocumentElement;

 

            foreach (XmlElement instance in root.GetElementsByTagName("Instance"))

            {

                InventoryInstanceGeneric inventoryInstance = new InventoryInstanceGeneric();

                inventoryInstance.ParentClass = instance.GetAttribute("ParentClass");

                inventoryInstance.Class = instance.GetAttribute("Class");

                inventoryInstance.Namespace = instance.GetAttribute("Namespace");

                inventoryInstance.Content = instance.GetAttribute("Content");

                inventoryInstance.RawXml = instance.InnerXml;

                tHINVMessage.AddInstanceToInventory(inventoryInstance);

            }

        }

 Note:

  1. The highlighted parts are necessary and need to happen at the specific order, otherwise you cannot generate the message correctly.
  2. Check MP log MP_Hinv.log and site server log dataldr.log for any errors.

    I had problems using the sample XML until we realized there was a case typo with the Class attribute of the Instance element. class="Package" ...should read... Class="Package"

    MP_HInv reports the following when using this sample HInv Sax: skipping unexpected token at Machine HInv Sax: skipping unexpected token at Machine Any suggestions
