使用C＃客户端与WMI远程连接时无法检索ASP.NET指标 [英] Cannot retrieve ASP.NET metrics when connecting remotely with WMI using a C# client

问题描述

只有部分代码。 但除了时间戳之外，所有相关值都返回0。

            System.Management.ManagementScope managementScope1 = new System.Management.ManagementScope（string.Format（" \\\\ {0} \\root \\cimv2"，strIP），options）;

            managementScope1.Connect（）;



            var query = new ObjectQuery（" SELECT  * FROM Win32_PerfRawData_ASPNET_ASPNETApplications"）;

            // var query = new ObjectQuery（" select * from Win32_PerfFormattedData_PerfOS_Processor"）;

            // var query = new ObjectQuery（" select * from Win32_PerfRawData_W3SVC_WebService"）;



$
            ManagementObjectSearcher searcher = new ManagementObjectSearcher（managementScope1，query）;



            foreach（Searcher.Get（）中的ManagementObject obj）

            {

                // var usage = obj [" PercentProcessorTime"];

                // var name = obj [" Name"];

                //Console.WriteLine（name +"：" + usage）;



                foreach（obj.Properties中的var propertyData）

                {

                    Console.WriteLine（" {0}：{1}"，propertyData.Name，propertyData.Value）;

                }


                Console.WriteLine（"完成"）;



                //Console.WriteLine（obj.ToString（））;

            }

您好yanguchong，

> ;>使用C＃客户端与WMI远程连接时无法检索ASP.NET指标

以下代码是如何使用C＃远程连接到WMI并获取一些指标。

 ConnectionOptions options = new ConnectionOptions（）; 
 options.Impersonation = System.Management.ImpersonationLevel.Impersonate; 
 ManagementScope scope = new ManagementScope（"\\\\.XXX.XXX.XXX \\\\\\\\\\\\\\\\ 
 scope.Connect（）; 
 
 //操作系统信息的查询系统
 ObjectQuery query = new ObjectQuery（" SELECT * FROM Win32_OperatingSystem"）; 
 ManagementObjectSearcher searcher = new ManagementObjectSearcher（范围，查询）; 
 ManagementObjectCollection queryCollection = searcher.Get（）; 
 StringBuilder sb = new StringBuilder（）; 
 foreach（queryObject在queryCollection中）
 {
 //显示远程计算机信息
 sb.AppendLine（" Computer Name" + m [" csname"]） ; 
 sb.AppendLine（" Windows Directory：" + m [" WindowsDirectory"]）; 
 sb.AppendLine（" Operating System：" + m [" Caption"]）; 
 sb.AppendLine（" Version：" + m [" Version"]）; 
 sb.AppendLine（" Computer Name" + m [" csname"]）; 
 sb.AppendLine（"制造商：" + m ["制造商]]）; 
 
 //Console.WriteLine("Computer Name：{0}"，m [" csname"]）; 
 //Console.WriteLine("Windows Directory：{0}"，m [" WindowsDirectory"]）; 
 //Console.WriteLine("Operating System：{0}"，m [" Caption"]）; 
 //Console.WriteLine("Version：{0}"，m [" Version"]）; 
 //Console.WriteLine("Manufacturer：{0}"，m [" Manufacturer"]）; 
} 
 MessageBox.Show（sb.ToString（））;

Only a partial of the code.  But all pertinent values return 0 except for timestamps.

            System.Management.ManagementScope managementScope1 = new System.Management.ManagementScope(string.Format("\\\\{0}\\root\\cimv2", strIP), options);
            managementScope1.Connect();

            var query = new ObjectQuery("SELECT  * FROM Win32_PerfRawData_ASPNET_ASPNETApplications");
            //var query = new ObjectQuery("select * from Win32_PerfFormattedData_PerfOS_Processor");
            //var query = new ObjectQuery("select * from Win32_PerfRawData_W3SVC_WebService");


            ManagementObjectSearcher searcher = new ManagementObjectSearcher(managementScope1, query);

            foreach (ManagementObject obj in searcher.Get())
            {
                //var usage = obj["PercentProcessorTime"];
                //var name = obj["Name"];
                //Console.WriteLine(name + " : " + usage);

                foreach (var propertyData in obj.Properties)
                {
                    Console.WriteLine("{0}:{1}", propertyData.Name, propertyData.Value);
                }

                Console.WriteLine("done");

                //Console.WriteLine(obj.ToString());
            }

Hi yanguchong,

>>Cannot retrieve ASP.NET metrics when connecting remotely with WMI using a C# client

The following code is how to Connecting to WMI Remotely with C# and get some metrics.

            ConnectionOptions options = new ConnectionOptions();
            options.Impersonation = System.Management.ImpersonationLevel.Impersonate;
            ManagementScope scope = new ManagementScope("\\\\12.XXX.XXX.XXX\\root\\cimv2", options);
            scope.Connect();

            //Query system for Operating System information
            ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection queryCollection = searcher.Get();
            StringBuilder sb = new StringBuilder();
            foreach (ManagementObject m in queryCollection)
            {
                // Display the remote computer information
                sb.AppendLine("Computer Name "+ m["csname"]);
                sb.AppendLine("Windows Directory : "+ m["WindowsDirectory"]);
                sb.AppendLine("Operating System: "+ m["Caption"]);
                sb.AppendLine("Version:"+ m["Version"]);
                sb.AppendLine("Computer Name " + m["csname"]);
                sb.AppendLine("Manufacturer :" + m["Manufacturer"]);

                //Console.WriteLine("Computer Name     : {0}", m["csname"]);
                //Console.WriteLine("Windows Directory : {0}", m["WindowsDirectory"]);
                //Console.WriteLine("Operating System  : {0}", m["Caption"]);
                //Console.WriteLine("Version           : {0}", m["Version"]);
                //Console.WriteLine("Manufacturer      : {0}", m["Manufacturer"]);
            }
            MessageBox.Show(sb.ToString());

>>Only a partial of the code.  But all pertinent values return 0 except for timestamps.

I also test your code. It can get some information. So, I think there is no problem to connect the remote machine to get the performance counter information.

I suggest you can ask your issue in the ASP.NET forum to get detailed information about how to retrieve ASP.NET metrics.

I found the following link give a solution. May be helpful for you.

ASP.NET performance data not available after installing .NET 4.5:

If you have some General WMI issue, you can visit the following forum.
