A new feature in SAS Decision Services 5.6 (SAS Real-Time Decision Manager 6.1) enables you to monitor the performance of your decision campaigns.

You can track both counts and response times as follows:

1. Record how many flows were executed during a specified time period.
2. Record how many times a specific node or nodes (scoped by flow or campaign) were executed during a specified time period.
3. Record the response time of flows, aggregated over a specified time period.

The second feature mentioned above is a particularly flexible feature. You can track how many times a flow is executed by tracking the counts of a Start node. You can track the number of times an Activity is called from a flow by tracking the activity Call node. You can also track the number of times a subflow is called from a flow by tracking the subflow Call node. Finally, you can count the number of times that SAS Decision Services returns the "standard" or fault response.

There are three options for specifying the sampling time period:

1. during a period with a specified start time and specified end time
2. since a specified time
3. until the current time (reset at restart of the SAS Decision Services Design Server or Engine Server)

The counts are useful even when running transactions in a batch, which is another feature of SAS Real-Time Decision Services 6.1 and SAS Decision Services 5.6.

These features are exposed by SAS Decision Services as a web service.

The SOAP call looks like this example:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dcsv="http://www.sas.com/xml/schema/sas-svcs/dcsv-1.1">
   <soapenv:Header/>
   <soapenv:Body>
      <dcsv:GetSystemStatistics/>
   </soapenv:Body>
</soapenv:Envelope>

Included below is some example output from the call. As you can see, it shows how many times the engine received an event, the node counts, and the average flow response time.
