SwyxWare v6.02 uses the standard Microsoft .Net tracing capabilities for newer components. Tracing is control via TraceSwitch objects which are set in the application configuration file, e.g.

<system.diagnostics>

  <switches>

    <add name="CDSClient" value="1" />

    <add name="GC" value="1" />

    <add name="MT" value="1" />

    <add name="PERFM" value="1" />

    <add name="IpPbxSrv" value="4" />

    <add name="PPool" value="1" />

    <add name="Files" value="1" />

    <add name="FileCache" value="1" />

    <add name="Report" value="1" />

    <add name="WSE" value="1" />

    <add name="SCT" value="1" />

    <add name="ChngMgmt" value="4" />

    <add name="ChngMgmtUser" value="4" />

  </switches>

</system.diagnostics>

I often have to change these settings on my development machine or on test systems. Instead of editing the file manually I use Windows Powershell: 

[0] C:\PS ADMIN> get-traceswitch "C:\Program Files (x86)\SwyxWare\IpPbxSrv.exe.config"
name                                                        value

PPool                                                       1
Files                                                       1
FileCache                                                   1
Report                                                      1

ChngMgmtUser                                                4
[0] C:\PS ADMIN> set-traceswitch "C:\Program Files (x86)\SwyxWare\IpPbxSrv.exe.config" Files 4
[0] C:\PS ADMIN> get-traceswitch "C:\Program Files (x86)\SwyxWare\IpPbxSrv.exe.config" Files
name                                                        value

get-traceswitch is defined like this:

function get-traceswitch($cfgFile,$switch)

{

    $c = [xml](get-content $cfgfile)

    $c.configuration.'system.diagnostics'.switches.add | ? { $_.name -match $switch }

}

The first line assigns the contents of the given config file to variable $c. [xml] ensures that it is of type System.Xml.XmlDocument. The second ine lists all "add" child elements of <switches> matching the given switch name. If $switch is empty the -match operator matches all.

set-traceswitch is almost as simple:

function set-traceswitch($cfgFile,$switch,$switchValue)

{

    $c = [xml](get-content $cfgFile)

    ($c.configuration.'system.diagnostics'.switches.add | where { $_.name -eq $switch }).value = [string]$switchValue

    $c.save($cfgFile)

}

I just retrieve the <add> element which has a name attribute matching the given switch name and set the value property of that element. BTW, setting the old style SwyxWare trace registry values is easy, too:

set-itemproperty hklm:\software\wow6432node\swyx\ippbxsrv\CurrentVersion\Tracing SrvGk 6

 I really like Windows Powershell
