[rules-users] Expiry of events not occurring for sliding window

I'll preface this by saying this may not be the correct way to do this, so suggestions welcome... For this example, the name can be something like 'collector1', 'collector2'. For each collector, there are normalized stats, like 'CPU', 'IO', etc. <pre> // Imports and other stuff declare InstanceHealth @role(event) @expires(10s) @timestamp(timeStamp) end rule "Iostats above 90 over 5 seconds" when $mih:InstanceHealth($id:id, $luid:name, $stat:stat ) from entry-point "stat-stream" $measure : Number( doubleValue > 90 ) from accumulate( InstanceHealth( $inst:name==$luid, $value:value, stat==$stat) over window:time( 5s ) from entry-point "stat-stream", average($value)) then logger.warn( "--------Average--------------" ); logger.warn( $mih.hashCode() + " // "+$stat +" // "+$id+" : "+$luid +" == "+$measure ); // doStuff based upon the name and stat end rule "Log instance" when $m:InstanceHealth($id:id, $stat:stat, $inst:name, $v:value ) from entry-point "stat-stream" then logger.warn( "------------Instance--------------" ); logger.warn( "--"+$inst+" == "+$stat +" value = "+$v ); end </pre> So the 'Iostats above 90 over 5 seconds' rule is trying to match up stats with collectors so there are no cross-products (stats aren't accumulated across collectors and each stat type gets it's own evaluation). This actually seems to be working, except the InstanceHealth objects don't seem to be being evicted and I'm apparently getting multiple activations (?). Note when I remove the line w/ the $mih binding, things get evicted fine but I don't have access to the name, stat, etc. TIA.
