Agree, however the following addition In addition to Duration SinceReset MAY also be set. -- Igor Sedukhin ..

[mailto:ian.springer@hp.com] Sent: Monday, March 28, 2005 2:31 PM To: wsdm@lists.oasis-open.org Subject: [wsdm] [interop] MOWS Metrics Act The MOWS metrics act says to "verify that metrics attributes are set correctly according to the type of metrics as indicated in the WSDM MOWS specification." The relevant section of the MOWS spec is 5.2.3.2. The last paragraph of this section says: --- Note that if a metric property has a <muws-xs2:TimeScope>SinceReset</muws-xs2:TimeScope> metadata value, the muws-xs2:ResetAt attribute MUST be reported on the property element and the muws-xs2:Duration attribute MUST NOT be reported. If a metric property has a <muws xs2:TimeScope>Interval</muws-xs2:TimeScope> metadata value, the muws-xs2:ResetAt attribute MAY be reported on the property element and the muws-xs2:Duration attribute MUST be reported. --- For five out of six of the MUWS metrics are described as having a TimeScope of _either_ SinceReset _or_ Interval. Being as there is no standard way defined for retrieving metadata, there doesn't seem to be any way for an interop client to determine the Timescope. I don't think we want to require interop service impls to provide WS-RMD metadata. To resolve this, I propose that we add the following to the MOWS metrics act: When validating that metric attributes are set correctly, assume that the NumberOfRequests, NumberOfFailedRequests, and NumberOfSuccessfulRequests metrics have a TimeScope metadata attribute value of "SinceReset", and that the ServiceTime and MaxResponseTime metrics have a TimeScope metadata attribute value of "Interval". This essentially means the client will verify that: 1) for the NumberOfRequests, NumberOfFailedRequests, and NumberOfSuccessfulRequests metrics: ResetAt attribute IS set, and Duration attribute IS NOT set and 2) for the ServiceTime and MaxResponseTime metrics: Duration attribute IS set Ian --------------------------------------------------------------------- To unsubscribe, e-mail: wsdm-unsubscribe@lists.oasis-open.org For additional commands, e-mail: wsdm-help@lists.oasis-open.org
