C＃WMI读取远程事件日志 [英] C# WMI reading remote event log

问题描述

我试着到最后5个小时左右的时间内对运行另一台计算机的错误WMI查询。当运行一个WMI查询，不应该你至少与过滤where子句初始查询？

Im trying to run a WMI query against another computer for errors within the last 5 hours or so. When running a WMI query, shouldnt you at least filter the initial query with a where clause?

林立足我的代码了从MSDN上的WMI代码创建者生成的样本

Im basing my code off of samples generated from the WMI code creator on MSDN

下面是选择查询即时通讯使用

Here is the select query im using

    private ManagementScope CreateNewManagementScope(string server)
    {
        string serverString = @"\\" + server + @"\root\cimv2";

        ManagementScope scope = new ManagementScope(serverString);

        return scope;
    } 

            ManagementScope scope = CreateNewManagementScope(servername);
            scope.Connect();
            SelectQuery query = new SelectQuery("select * from Win32_NtLogEvent where TimeWritten > '" + DateTime.Now.AddHours(-5).ToString() + "'");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection logs = searcher.Get();

            int iErrCount = logs.Count;

我只想得到错误的计数在过去的5个小时。其获得数时抛出一个错误。该错误是相当模糊的通用失败

I just want to get a count of the errors in the last 5 hours. Its throwing an error when getting the count. The error is rather vague "Generic Failure".

[更新 - 使用日期现在这个样子]

[update - using date like this now]

                DateTime d = DateTime.UtcNow.AddHours(-12);
            string dateFilter = ManagementDateTimeConverter.ToDmtfDateTime(d);
            SelectQuery query = new SelectQuery("select * from Win32_NtLogEvent where Logfile='Application' AND Type='Error' AND TimeWritten > '" + dateFilter + "'");

通过上面的代码我没有得到任何结果，但我可以看到在事件日志中2个错误。什么错日期过滤器？

With the above code I get no results, yet I can see 2 errors in the event log. Whats wrong with the date filter?

即时通讯使用这个例子

推荐答案

我做了以下才能正常工作。我希望这有助于..

I did the following to get it to work. I hope this helps..

    static void Main(string[] args)
    {
        var conOpt = new ConnectionOptions();
        conOpt.Impersonation = ImpersonationLevel.Impersonate;
        conOpt.EnablePrivileges = true;
        conOpt.Username = "username";
        conOpt.Password = "password";
        conOpt.Authority = string.Format("ntlmdomain:{0}", "yourdomain.com");

        var scope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", "yourservername.yourdomain.com"), conOpt);

        scope.Connect();
        bool isConnected = scope.IsConnected;
        if (isConnected)
        {

            /* entire day */ string dateTime = getDmtfFromDateTime(DateTime.Today.Subtract(new TimeSpan(1, 0, 0, 0)));
            string dateTime = getDmtfFromDateTime("09/06/2014 17:00:08"); // DateTime specific

            SelectQuery query = new SelectQuery("Select * from Win32_NTLogEvent Where Logfile = 'Application' and TimeGenerated >='" + dateTime + "'");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection logs = searcher.Get();
            foreach (var log in logs)
            {
                Console.WriteLine("Message : {0}", log["Message"]);
                Console.WriteLine("ComputerName : {0}", log["ComputerName"]);
                Console.WriteLine("Type : {0}", log["Type"]);
                Console.WriteLine("User : {0}", log["User"]);
                Console.WriteLine("EventCode : {0}", log["EventCode"]);
                Console.WriteLine("Category : {0}", log["Category"]);
                Console.WriteLine("SourceName : {0}", log["SourceName"]);
                Console.WriteLine("RecordNumber : {0}", log["RecordNumber"]);
                Console.WriteLine("TimeWritten : {0}", getDateTimeFromDmtfDate(log["TimeWritten"].ToString()));
            }
        }

        //ReadLog();
        Console.ReadLine();
    }

    private static string getDmtfFromDateTime(DateTime dateTime) 
    {
        return ManagementDateTimeConverter.ToDmtfDateTime(dateTime);
    }

    private static string getDmtfFromDateTime(string dateTime)
    {
        DateTime dateTimeValue = Convert.ToDateTime(dateTime);
        return getDmtfFromDateTime(dateTimeValue);
    }

    private static string getDateTimeFromDmtfDate(string dateTime)
    {
        return ManagementDateTimeConverter.ToDateTime(dateTime).ToString();
    }
