When creating the summary line, WebMDS looks at four RFT resource properties: 
ActiveResourceInstances, TotalNumberOfActiveTransfers, NumberOfBytesTransferred,
and NumberOfTransfers.  It looks like when the RFTFactoryService starts up, it
only advertizes ActiveResourceInstances, and not the other three.

I have RFT resource which has been up for a long time being presented the same
way. Querying the service also shows more info:

Ah -- what's going on is that the aggregator source for the RFT factory service
is configured to query only for the ActiveResourceInstances property (you can
see a prettier version of this if you click on the detail line for the RFT
factory service in the webmds display):

<ns11:AggregatorConfig>
  <ns11:GetResourcePropertyPollType>
    <ns11:PollIntervalMillis>300000</ns11:PollIntervalMillis>
   
<ns11:ResourcePropertyName>rft:ActiveResourceInstances</ns11:ResourcePropertyName>
  </ns11:GetResourcePropertyPollType>
</ns11:AggregatorConfig>

The RFT factory should probably use the GetMultipleResourcePropertiesPollType
and get more resource properties (there's an example of this configuration for
RFT in $G_L/etc/globus_wsrf_mds_aggregator/example-aggregator-registration.xml).

I commited changes suggested by Laura. Let me know if it works well
