StreamInsight Wcf具有弹性的示例

我开始了解StreamInsight(v2.1!)并开始基于StreamInsight团队的WCF示例开发应用程序。 现在我想为该应用程序添加弹性和监视,但无法弄清楚如何。我试过按照Checkpointing Sample和这些教程,但没有运气: http://msdn.microsoft.com/en-us/library/hh290476(v=sql.111).aspx

我应该调整WcfObservable吗?或者我应该如何为我的observable,观察者和查询添加弹性?

这是我的代码的一部分:

var wcfIn = app.DefineObservable(() => new WcfObservable(wcfSourceURL));
var wcfStream = wcfIn.ToPointStreamable(i => PointEvent.CreateInsert<Measurement>(i.T, i.M),
                                             AdvanceTimeSettings.IncreasingStartTime);

//Check measurements for deflections
var deflectionQuery = from r in wcfStream
                      where r.Value > measurableValue * 1 + threshhold || r.Value < measurableValue * 0 + threshhold
                      select new OutputEvent
                      {
                           M = r,
                           Deflection = (r.Value - measurableValue) / measurableValue,
                           Error = "Deflection"
                      };
var sqlObserver = app.DefineObserver(() => Observer.Create<OutputEvent>(SqlWritePoint));
proc = deflectionQuery.Bind(sqlObserver).RunCheckpointable(procName);

提前感谢您的时间!
