Up until 7.0 there were a set of Windows performance counters exposed by the web player. We used to monitor these counters using third party monitoring tools - e.g. we were able to chart the "web player MB available before swapping to disk" metric over time and use it to aid our capacity planning. Since 7.5 these counters are no longer available as performance counters, although they are available in the performance log stored on the server. I'd like to see the performance counters reinstated since they are far easier to pull into third party tools than a set of values stored in a file on the server. I also believe the logic for generating the counters is still likely present in the code given that they are written to files.
I've heard from support that this "isn't possible" because of the re-architecture, but I'm not buying that! The application is still a .NET application and under the covers no doubt includes much of the code from the pre-7.5 architecture. It's also disappointing that this feature simply disappeared without any documentation to that effect - I'm suspicious it was simply forgotten during the 7.5 release.
Gets my vote but I doubt it will get implemented. Spotfire is not just .Net. The whole server stack is Java hence why it runs on Tomcat (a Java App Server). In fact a lot (like Scheduled Updates) of the Web Player server features moved to the Spotfire Server so I suspect that is the main reason of this change. Have you looked at the Server JMX interface? There are some server statistics over there so perhaps we should push for more data to be exposed there which should be a lot easier for Tibco.
