Mesasge Analyzer自定义图表 [英] Mesasge Analyzer Custom Chart

问题描述

创建自定义图表时如何执行更复杂的数据绑定？我有一个网络跟踪，我想绘制一些https clienthello数据。具体来说，你好的client_version。我可以将记录[0] .fragment [0] .body.client_version
添加到分析网格中，它在那里显示正常。当我尝试将它添加到我的新图表的数据选项卡中的行字段时，我得到一个例外。如果我只输入"记录"进入Row Fields看起来它显示RecordLayers对应的
ToString函数。如果我输入记录[0]则不显示任何内容。如果我输入记录[0] .fragment，我会得到以下异常：

How do I perform more complex data binding when creating a custom chart? I have a network trace and I want to chart some of the https clienthello data. Specifically, the client_version of the hello. I can add records[0].fragment[0].body.client_version to the Analysis Grid and it displays fine there. When I try to add it to the Row Fields in the Data tab of my new chart I get an exception. If I enter just "records" into the Row Fields it looks like it displays the RecordLayers corresponding ToString function. If I enter records[0] it displays nothing. If I enter records[0].fragment I get the following exception:

绑定到数组是否有效？此外，如果消息堆栈中有两个具有相同名称的字段，您如何明确指定要使用的字段？它似乎使用了消息堆栈中最顶端的字段。

Does binding to arrays work? Also, if there are two fields with the same name in the message stack, how do you explicitly specify which field you want to use? It appears to use the top most field in the message stack.

推荐答案

我能够重现崩溃，我提交了一个错误。

I was able to repro the crash and I filed a bug.

至于引用记录的版本字段，似乎可以限制哪些图表可以绑定。 我将提交一个错误来解决这个问题，但是我可以在短期内为您提供解决方案。 您可以通过编写
一些简单的OPN来创建属性。 然后改为引用该属性。 只需创建一个名为TLSExt.OPN的文件，将下面的内容放入其中，然后将其复制到您的用户\YOURID \ AppData \ Local \ Microsoft \ MyessAnalyzer \OpnAndConfiguration \Opns目录。 如果您升级
或卸载，则您的更改将会丢失。 所以请在此位置以外保留副本。

As for referencing the version field of a record, there seems to be a limitation with what charts can be bound to.  I will file a bug to address this, however I can give you a work-around for the short term.  You can create a property by writing some simple OPN.  Then reference that property instead.  Just create a file called TLSExt.OPN, put the contents below, and copy it to your users\YOURID\AppData\Local\Microsoft\MessageAnalyzer\OpnAndConfiguration\Opns directory.  If you upgrade or uninstall, your changes will be lost.  So keep a copy outside this location.

模块TLSExt;

使用TLS;

string get TLSVersion （此TLS.RecordLayers rl）

{

  return rl.records [0] .version.ToString（）;

}

string get TLSVersion(this TLS.RecordLayers rl)
{
 return rl.records[0].version.ToString();
}

如果您有任何疑问，请告诉我。

Let me know if you have questions.

谢谢，
