Ahh didn't realise it was a standard thing packaged with the SDK. SWFDump confirms the advanced telemetry flag is set to true.
A slight bit of progress.....I think IE was caching the SWF file and using that (which didn't have the telemetry on). I've purged all versions from the cache and now Scout is showing "Advanced Telemetry : Enabled" in the session info Telemetry section. However, clicking on all the session options ("ActionScript Sampler" etc.) I am not getting any output in the sections at the bottom of Scout. I can see the timeline along the top doing stuff but no actual useful debug information (as per screenshot): http://i629.photobucket.com/albums/uu19/drevans112/Allocate/ScoutTimelineActivityNoOutput.png What am I missing now? jmclean wrote > In the bin directory of Apache Flex binary release or a from a compiles > Apache Flex source release. -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Enable-Advanced-Telemetry-tp7695p7748.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
