You can accumulate the minimum as well: accumulate( Reading ( $r:reading) over windiw:time(30s) from entry-point HeartrateStream; $avg: average($r), $min: min($r); $min > 90 )
This tells you that all readings are over 90. -W On 28 February 2014 15:25, Lin Lin <lin....@comcast.net> wrote: > > > > > On Feb 27, 2014, at 4:06 PM, "lin.lin [via Drools]" < > ml-node+s46999n4028396...@n3.nabble.com> wrote: > > Hi > > Thanks again for the pointers!! > > I modified the code but the sliding window rule does not seem to be > working as how I want it to be(copied shown in the following).
