What's Inside

If you are administering (or somehow related to) any kind of network, you may wish to periodically acquire a more-or-less complete image of what's happening in your PCs. The presented script was created to ease the task of keeping track of hardware and software components throughout the enterprise; it queries all the WMI classes that I think are useful to monitor. The script was designed to accomplish the following goals:

collect information about crucial characteristics of a selected computer(s)
maximize interoperability, that results in serializing the collected data to XML
provide an extensible framework for building administrative tools upon WMI services

This article is in no way a tutorial on WMI; it just explains what the accompanying tool is and how it works. Using the tool doesn't require anything beyond the basic knowledge of Windows Management Instrumentation; understanding and extending the tool requires a programming experience with Windows Scripting Host, JScript language and Microsoft XML library.

Frontend

The common way of using the tool is through the wmi_admin.hta page. UI is fairly obvious.

First tab allows you to type in the IPs or IP ranges you want to query.

On the second tab you can select what info will be gathered. There q plenty of options to choose from.

Third tab can be used to enter administrator's options.

On the last tab you'll press the "Run query" button and will see the tests running.

Doing It the Hard Way

Script (scripts/wmiadmin.js) can be also run from the command line.

Starting it all
You can run the script by running the wmiadmin.js file. Shell command:
```
[cscript] wmiadmin.js
```
collects info on the local computer and opens the resulting XML file (named result-127-0-0-1.xml) in a browser; and
```
[cscript] wmiadmin.js xxx.xxx.xxx.xxx
```
collects info about the computer whose IP address is xxx.xxx.xxx.xxx, creates the resulting XML file named result-xxx-xxx-xxx-xxx.xml and opens it in a browser. You can specify any number of IP addresses as you wish:
```
[cscript] wmiadmin.js xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy zzz.zzz.zzz.zzz
```
creates result-xxx-xxx-xxx-xxx.xml, result-yyy-yyy-yyy-yyy.xml, result-zzz-zzz-zzz-zzz.xml files and opens them in a browser.

Specifying /silent key runs the script in a 'silent mode':
```
[cscript] wmiadmin.js /silent
```
collects info about the local computer and doesn't show the resulting XML file;
```
[cscript] wmiadmin.js /silent xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
```
collects info about the computers with IPs xxx.xxx.xxx.xxx and yyy.yyy.yyy.yyy, and doesn't show the resulting XML files.

Specifying /username:name and /password:pass gives you a chance to use alternative credentials instead of those provided by the system:
```
[cscript] wmiadmin.js /username:alice /password:anywordyoulike 
                            xxx.xxx.xxx.xxx
```
collects info about the computer with IP xxx.xxx.xxx.xxx using username alice and password anywordyoulike and shows the resulting XML file.

/domain and /auth keys allow you to specify the target domain and the way you authenticate on this domain. If this key value is equal to "kerberos", Kerberos authentication is used; otherwise, NTLM authentication is used:
```
[cscript] wmiadmin.js /domain:acme /username:alice 
        /password:anywordyoulike /auth:kerberos xxx.xxx.xxx.xxx
```

Collecting data

The process of gathering system info consists of:

WMI connection setup:

JavaScript

this._SetupService = function(ip)
{
  if(!this._service[ip])
  {
    var locator = new ActiveXObject("WbemScripting.SWbemLocator");

    this._service[ip] = locator.ConnectServer(ip, "root\\cimv2",
                     this._username, this._password, "", 
                        this._domain ?
                    (this._kerberos ? ("kerberos:" + this._domain) :
                    ("NTLMDOMAIN:" + this._domain)) : "");

    this._service[ip].Security_.ImpersonationLevel = 3;
  }

  this._curserv = this._service[ip];
}

Actual query. All the WMI queries are made through _ExecQuery or _ExecQueryWithWhereClause methods of WMIcollector object:

JavaScript

this._ExecQuery = function(className)
{
  return this._curserv.InstancesOf(className);
}

this._ExecQueryWithWhereClause = function(className, condition)
{
  return this._curserv.ExecQuery("Select * from " + className + 
                    " Where " + condition);
}

The following is one of the many query routines:

JavaScript

this._collect1394ControllerInfo = function()
{
  var fc = new Enumerator(runQuery("Win32_1394Controller"));

  var xmlDoc = null, colItem = null, numItems = 0;
  for (; !fc.atEnd(); fc.moveNext())
    numItems++;

  if(numItems > 0)
  {
    xmlDoc = new ActiveXObject("Msxml2.DOMDocument");

    if(numItems > 1)
    {
      colItem = xmlDoc.createElement("Item");
      xmlDoc.appendChild(colItem);
      this._xmlSetAttribute(xmlDoc, colItem, "name", 
                            "IEEE 1394 Controllers");
    }

    var i = 1;
    for (fc.moveFirst(); !fc.atEnd(); fc.moveNext())
    {
      var Obj = fc.item();

      var root, num = "";
      if(colItem != null)
      {
        root = xmlDoc.createElement("Element");
        num = " " + String(i);
      }
      else
      {
        root = xmlDoc.createElement("Item");
      }

      this._xmlSetAttribute(xmlDoc, root, "name", 
                            "IEEE 1394 Controller" + num);
      if(colItem != null)
      {
        colItem.appendChild(root);
      }
      else
      {
        xmlDoc.appendChild(root);
      }

      this._xmlCreateChildTextNode(xmlDoc, root, "Availability",
                      translate_availability(Obj.Availability));
      this._xmlCreateChildTextNodeWithAttribute(xmlDoc, root, 
                      "DeviceID", Obj.DeviceID, "name", "Device ID");
      this._xmlCreateChildTextNode(xmlDoc, root, 
                      "Manufacturer", Obj.Manufacturer);
      this._xmlCreateChildTextNode(xmlDoc, root, "Name", Obj.Name);
      this._xmlCreateChildTextNode(xmlDoc, root, "Status", 
                                   Obj.Status);

      i++;
    }
  }

  return xmlDoc;
}

Building the XML Tree

Five helper functions - a thin wrapper to Microsoft XML parser - are used. Common parameters are:

doc - an object of type Msxml2.DOMDocument
parent, node - object(s) of type IXMLDOMElement
nodeName, attributeName - character strings that are suitable as node/attribute names
attributeValue, nodeContent - any character string

JavaScript

// Add an attribute to node.
this._xmlSetAttribute = function(doc, node, attributeName, 
                                            attributeValue)
{
  var Attribute = doc.createAttribute(attributeName);
  var AttributeText = doc.createTextNode(this._trim(attributeValue));

  Attribute.appendChild(AttributeText);
  node.setAttributeNode(Attribute);
}

// Create a child node and append it to parent node.
this._xmlCreateChildNode = function(doc, parent, nodeName)
{
  var Element = doc.createElement(nodeName);

  parent.appendChild(Element);

  return Element;
}

// Create a child node and append it to parent node;
// then add an attribute to newly created child node.
this._xmlCreateChildNodeWithAttribute = function(doc, parent, 
                      nodeName, attributeName, attributeValue)
{
  var Element = doc.createElement(nodeName);

  parent.appendChild(Element);

  this._xmlSetAttribute(doc, Element, attributeName, attributeValue);

  return Element;
}

// Create a child node and append it to parent node;
// populate child node with nodeContent.
this._xmlCreateChildTextNode = function(doc, parent, nodeName, 
                                                   nodeContent)
{
  var str = this._trim(String(nodeContent));

  if(this._isempty(str)) return null;

  var Element = doc.createElement(nodeName);
  var ElementText = doc.createTextNode(str);

  parent.appendChild(Element);
  Element.appendChild(ElementText);

  return Element;
}

// Create a child node and append it to parent node;
// populate child node with nodeContent, then add an
// attribute to newly created child node.
this._xmlCreateChildTextNodeWithAttribute = function(doc, parent, 
             nodeName, nodeContent, attributeName, attributeValue)
{
  var str = this._trim(String(nodeContent));

  if(this._isempty(str)) return null;

  var Element = doc.createElement(nodeName);
  var ElementText = doc.createTextNode(str);

  parent.appendChild(Element);
  Element.appendChild(ElementText);

  this._xmlSetAttribute(doc, Element, attributeName, attributeValue);

  return Element;
}

The resulting XML tree has the following structure:

XML

<Root>
  <Metadata>
    <IP> - IP address queried
    <Date> - Date (local) when the query was run

    <Time> - Time (local) when the query was run

  <Hardware>
    <Item name="item name"> - 
          in case of a single item under a category

      <characteristic1 name="characteristic1 name">
      ...
      <characteristicN name="characteristicN name">
    ...
    <Item name="item collection name"> - 
             in case of several items under one category

      <Element name="name of a distinct item">
        <characteristic1 name="characteristic1 name">
        ...
        <characteristicN name="characteristicN name">

      ...
    ...

  <Software> - the same substructure as in <Hardware>
    ...

Gathering the Result

The RunQuery method of WMIcollector object is, actually, the main function of the script:

JavaScript

this.RunQuery = function()
{
  for(var i = 0; i < this._ip.length; i++)
  {
    var cur_ip = this._ip[i];

    // Main call:
    this._xml[cur_ip] = this._collectAll(cur_ip);
  }
}

_collectAll, in turn, calls all the info-collecting functions.

Viewing the Result

The script flow can be described as:

construct an output file name from the IP address (xxx.xxx.xxx.xxx) in the format: result-xxx-xxx-xxx-xxx.xml, where xxx are the parts of the given IP address
gather info
write the collected info (in the form of XML tree) to the output file
programmatically open the newly created file in a browser (only if not in the silent mode)

All of the above (except 2^nd item) is done outside of WMICollector object:

JavaScript

if(typeof(WScript) == "object")
{
  var local_ip = "127.0.0.1";

  var wmic = null;
  var Args = WScript.Arguments;

  if(!Args.length)
  {
    wmic = new WMIcollector(local_ip); 
  }
  else
  {
    var ArgsNamed = Args.Named, ArgsUnnamed = Args.Unnamed;

    var username = ArgsNamed.Exists("username") ? 
                ArgsNamed.Item("username") : null;
    var password = ArgsNamed.Exists("password") ? 
                ArgsNamed.Item("password") : null;
    var domain   = ArgsNamed.Exists("domain")   ? 
                ArgsNamed.Item("domain")   : null;

    var silent = ArgsNamed.Exists("silent");
    var secure = ArgsNamed.Exists("auth") ? 
            (ArgsNamed.Item("auth") == "kerberos") : false;

    var ips = [];
    for(var i = 0; i < ArgsUnnamed.length; i++)
     ips[ips.length] = ArgsUnnamed(i);

    if(!ips.length) ips[0] = local_ip;

    wmic = new WMIcollector(ips, username, password, domain, secure);
  }

  wmic.RunQuery();

  var fso = new ActiveXObject("Scripting.FileSystemObject");

  // SAXreader/MXXMLwriter are used to create & save 'neat' xml files.
  //
  var writer = new ActiveXObject("Msxml2.MXXMLWriter.3.0");

  writer.indent = true;            // write xml in a 'pretty printed'-way
  writer.omitXMLDeclaration = true;

  var reader = new ActiveXObject("Msxml2.SAXXMLReader.3.0");

  reader.contentHandler = writer;
  reader.errorHandler = writer;
  //
  // You can also use 'Msxml2.SAXXMLReader.4.0' and 
  // 'Msxml2.MXXMLWriter.4.0'
  // (= more detailed error messages) with MSXML 4.0 (or higher) 
  // installed.

  for(ip in wmic._xml)
  {
    var fname = "result-" + String(ip).replace(/\./g, "-") + ".xml";

    // Note on creating & saving xml files:
    //
    // if you are sure that computers you query return nothing that falls
    // out of an ordinary ASCII charset, you may wish to switch back to
    // saving single-byte data (by switching the last parameter of 
    // 'CreateTextFile' to 'false' and changing 'encoding' variable to 
    // 'UTF-8', 'iso-8859-1',
    // 'Windows-1250' or anything that fits your locale), thus saving
    // ~50% of disk space.
    //
    // 1st parameter - file name;
    // 2nd parameter - overwrite existing file (true/false);
    // 3rd parameter - create unicode (true) or ASCII(false) file.
    //
    var xmlFile = fso.CreateTextFile(fname, true, true);

    // Change this encoding to any that fits:
    // (having created the unicode file, you should keep it UTF-16)
    //
    var encoding = "UTF-16";

    reader.parse(wmic._xml[ip]);

    xmlFile.WriteLine("<?xml version=\"1.0\" encoding=\"" + 
                        encoding + "\"?>");
    xmlFile.WriteLine("<?xml-stylesheet type=\"text/xsl\" 
                    href=\"wmiadmin.xsl\"?>");
    xmlFile.Write(writer.output);

    //  You can comment all the preceeding SAXreader/
    //  MXXMLwriter stuff and uncomment the following line to:
    //  1) write 'unformatted' (single-line) xml to a file, 
    //  thus save ~7-10% disk space;
    //  2) speed things up.

    //  xmlFile.Write("<?xml version=\"1.0\" encoding=\"" + 
    //  encoding + "\"?><?xml-stylesheet type=\"text/xsl\" 
    //  href=\"wmiadmin.xsl\"?>" + result.xml);

    xmlFile.Close();

    if(!silent)
    {
      var Path = WScript.ScriptFullName;
      Path = Path.substring(0, Path.lastIndexOf("\\"));

      // To view using MS IE:
      var ie = new ActiveXObject("InternetExplorer.Application");
      ie.visible = true;
      ie.navigate("file://" + Path + "/" + fname);

      // To view the file in your default browser:
   /* var shl = new ActiveXObject("WScript.Shell");
      shl.Run(fname); */
    }
  }
}

Sample Stylesheet
One more thing to look at is the wmiadmin.xsl file (included in the accompanying archive). This rather straightforward XSLT stylesheet is an example of how you can convert the resulting XML tree to a more readable form.

Gotchas

There are several pitfalls you must be aware of:

Pinging

A PC's availability can be checked by pinging the target computer through Win32_PingStatus. However, this class is only accessible in Windows XP / Windows 2003 Server (or later). Under other versions of Windows, you must explicitly call the ping utility and analyze its output:

JavaScript

function Ping(ip)
{
  if(ip == "") ip = "127.0.0.1";

  var oShell = new ActiveXObject("WScript.Shell");
  var oScriptExec = oShell.Exec("ping -n 2 -w 1000 " + ip);
  var strPingResults = oScriptExec.StdOut.ReadAll();
  strPingResults.toLowerCase();

  if(strPingResults.indexOf("reply from") != -1)
  {
    // ping's answer depends on Windows language version,
    // so be careful:
    //
    if(strPingResults.indexOf("destination net unreachable") != -1)
    {
      return (ip + "did not respond to ping.");
    }
    else
    {
      return (ip + " responded to ping.");
    }
  }
  else
    return (ip + " did not respond to ping.");
}

Property Arrays

All the arrays that WMI provides are VB-safearrays and cannot be indexed directly. Use the Enumerator object:

JavaScript

// Extracting info from BiosCharacteristics[] array of 
// <a href="%22%22http://msdn.microsoft.com/library/en-us/wmisdk/wmi/win32_bios.asp%22%22">Win32_BIOS</a> class:
if(Obj.BiosCharacteristics != null)
{
  var char_node = this._xmlCreateChildNodeWithAttribute(xmlDoc, root, 
                     "BIOSCharacteristics", "name", "BIOS Features");

  var i_count = 1;

  // Convert VB safearray to JS array:
  var chars_ar = Obj.BiosCharacteristics.toArray();
  var chars_en = new Enumerator(chars_ar);

  // Iterate through the array:
  for (; !chars_en.atEnd(); chars_en.moveNext())
  {
    var ch_obj = chars_en.item();
    this._xmlCreateChildTextNodeWithAttribute(xmlDoc, char_node,
           "Characteristic_" + String(i_count),
           translate_bios_feats(ch_obj), "name", 
           "Feature " + String(i_count));

    i_count++;
  }
}

Attribute Bitmaps

A very special case of property is the "attribute bitmap", which contains a merger (produced by logical OR) of several distinct values. These values can be extracted by testing the bitmap (with the logical AND) against every possible value that it can contain:

JavaScript

// Taken from <a href="%22%22http://msdn.microsoft.com/library/en-us/wmisdk/wmi/win32_printer.asp%22%22">Win32_Printer</a> handler:
var attrib_node = 
     this._xmlCreateChildNode(xmlDoc, root, "Attributes");

if(Obj.Attributes & 0x1)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                     "Attribute1", "true", "name", 
                     "Print jobs are buffered and queued");
if(Obj.Attributes & 0x2)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
            "Attribute2", "true", "name", 
            "Document to be sent directly to the printer");
if(Obj.Attributes & 0x4)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                          "Attribute3", "true", "name", 
                          "Default printer on a computer");
if(Obj.Attributes & 0x8)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                 "Attribute4", "true", "name", 
                 "Available as a shared network resource");
if(Obj.Attributes & 0x10)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                              "Attribute5", "true", "name", 
                              "Attached to a network");
if(Obj.Attributes & 0x20)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                  "Attribute6", "true", "name", 
                  "Hidden from some users on the network");
if(Obj.Attributes & 0x40)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                       "Attribute7", "true", "name", 
                       "Directly connected to a computer");
if(Obj.Attributes & 0x80)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
           "Attribute8", "true", "name", 
           "Enable the queue on the printer if available");
if(Obj.Attributes & 0x100)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                      "Attribute9", "true", "name", 
                      "Spooler should not delete" + 
                      " documents after they are printed");
if(Obj.Attributes & 0x200)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
            "Attribute10", "true", "name", 
            "Start jobs that are finished spooling first");
if(Obj.Attributes & 0x400)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, 
        attrib_node, "Attribute11", "true", "name", 
        "Queue print jobs when a printer is not available");
if(Obj.Attributes & 0x800)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
                          "Attribute12", "true", "name", 
                          "Enable bi-directional printing");
if(Obj.Attributes & 0x1000)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
             "Attribute13", "true", "name", 
             "Allow only raw data type jobs to be spooled");
if(Obj.Attributes & 0x2000)
  this._xmlCreateChildTextNodeWithAttribute(xmlDoc, attrib_node, 
              "Attribute14", "true", "name", 
              "Published in the network directory service");

Uint-to-string Translations

Many properties are of the type integer. To convert any of these uints to readable form, you must write a translation function like this:

JavaScript

// For 'availability' property:
this._translate_availability(code)
{
  if(this._isempty(code)) return "";

  switch(code)
  {
    case 1: return "Other"; break;
    case 3: return "Running / Full Power"; break;
    case 4: return "Warning"; break;
    case 5: return "In Test"; break;
    case 6: return "Not Applicable"; break;
    case 7: return "Power Off"; break;
    case 8: return "Off Line"; break;
    case 9: return "Off Duty"; break;
    case 10: return "Degraded"; break;
    case 11: return "Not Installed"; break;
    case 12: return "Install Error"; break;
    case 13: return "Power Save - Unknown"; break;
    case 14: return "Power Save - Low Power Mode"; break;
    case 15: return "Power Save - Standby"; break;
    case 16: return "Power Cycle"; break;
    case 17: return "Power Save - Warning"; break;
    default: return "Unknown"; break;
  }
}

Functions have been written for (almost) every 'translatable' property. If you notice something uncovered, please let me know.

Correct XML Encoding
This problem falls into two parts:
- Creating a file with correct encoding (ASCII or Unicode)
- Specifying the encoding for XML tree
Both tasks are performed by two lines of code in the RunQuery method:

JavaScript
```
this.RunQuery = function()
{
  ...

  // The 3rd parameter - 'true' - says that we're 
  // creating a Unicode file.
  var xmlFile = fso.CreateTextFile(fname, true, true);

  // XML tree charset:

  var encoding = "UTF-16";

  ...
}
```
Joining Unicode-type file and UTF-16 XML tree together is the universal method for delivering compatible XML files. However, if you are absolutely sure that computers you query return nothing that falls out of an ordinary ASCII charset, you may wish to switch back to saving single-byte data (by switching the last parameter of 'CreateTextFile' to 'false' and changing the 'encoding' variable to 'UTF-8', 'iso-8859-1', or any other charset that fits your locale), thus saving 50% of the disk space.

Neat vs. Raw

For production (or just aesthetic) purposes, it may be useful to write XML tree in a 'neat', i.e. indented style. This is done by using SAXXMLReader and MXXMLWriter objects:

JavaScript

this.RunQuery = function()
{
  ...

  // SAXreader/MXXMLwriter are used to create & save 'neat' xml files.
  //
  var writer = new ActiveXObject("Msxml2.MXXMLWriter.3.0");

  writer.indent = true;          // write xml in a 'pretty printed'-way
  writer.omitXMLDeclaration = true;

  var reader = new ActiveXObject("Msxml2.SAXXMLReader.3.0");

  reader.contentHandler = writer;
  reader.errorHandler = writer;
  //
  //You can also use 'Msxml2.SAXXMLReader.4.0' and 
  //'Msxml2.MXXMLWriter.4.0'
  //(= more detailed error messages) with MSXML 4.0 (or higher) installed.

  ...

  var result = this._collectAll(cur_ip);

  // result now contains xml complete tree (w/o xml declaration)

  reader.parse(result.xml);

  xmlFile.WriteLine("<?xml version=\"1.0\" encoding=\"" + encoding);
  xmlFile.WriteLine("\"?>");
  xmlFile.WriteLine("<?xml-stylesheet type=\"text/xsl\" ");
  xmlFile.WriteLine("href=\"wmiadmin.xsl\"?>");
  xmlFile.Write(writer.output);

  xmlFile.Close();

  ...
}

Nevertheless, you can always switch to a simpler (== faster) method of writing a single-line file (which will save you ~7-10% of the disk space):

JavaScript

...

xmlFile.Write("<?xml version=\"1.0\" encoding=\"" + encoding +
  "\"?><?xml-stylesheet type=\"text/xsl\" href=\"wmiadmin.xsl\"?>" +
  result.xml);

xmlFile.Close();

...

Achieved Milestones

Time has come to review the results and think of the future.

The list of WMI classes and properties has been assembled, and the appropriate code has been set up
WMI setup and query procedures have been created
XML tree construction and serialization procedures have been created
Several options (silent mode, multiple IPs) installed, with all major problems addressed (including internationalization and Unicode interoperability issues)
UI is up and running

Evolution of wmiadmin tool is not finished. Feel free to write to me all your opinions and suggestions, bugs you've faced and features you'd like to see.
