<br> There are 2 important concepts related to time windows. First and most important, sliding windows only work in STREAM_MODE, not in CLOUD_MODE (default). Did you set the engine to STREAM_MODE?<br> Second, the session clock becomes really important in STREAM_MODE: what clock are you using? Real time or pseudo clock?<br>

<p><font color="navy" size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">I understand what you are saying about
Expert+Fusion and that was my understanding as well and I have been reading
through the docs on that links, however I have not read all of the documentation
exhaustively yet. There doesn’t seem to be a lot of samples(syntax
wise) for authoring rules taking advantage of those Fusion features.
There are isolated one or two line samples, but I guess I am having a difficult
time determining how to author rules based on collections of data…think
of sensor data over time….so I want to author rules that work on the
latest readings plus some configurable amount of readings in the past.
>From the Fusion features description, it seems ideal….but finding out the
nuts and bolts of implementing it is eluding me thus far. </span></font></p>

Chris,<br>
<br>
Fusion is an extension of Drools Expert. Think about it as all
Expert features + some additional features. That is why Drools Fusion docs is
just a list of features explained.<br>
<br>
I assume you looked here already:<br>
<br>
<a href="http://www.jboss.org/drools/documentation.html" target="_blank">http://www.jboss.org/drools/documentation.html</a><br>
<br>
For both, expert and fusion docs.<br>
<br>
So, back to your rule, syntax seems correct to me. Why do you say
it is not working? What error or symptoms do you see?<br>
<br>

<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I
am trying to write a rule for a moving average over values over the last minute
using fusion. In general I can’t seem to locate a detailed resource
for authoring syntax for these types of rules or rules in general, but
specifically, I tried to modify something from the fusion documentation for my
purposes using the StockTicker fusion sample. Here is the rule entry I
aded to the broker.drl:</span></font></p>

<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I
basically want to be alerted any time the moving average for ORCL moves above
127 (or whatever criteria I set…I picked that based on the sample data
the sample fusion project uses), but it doesn’t seem to be working.
</span></font></p>
<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I
guess if I could locate the definitave samples or guide for authoring these
types of rules I could use that, but it’s very difficult to piece
together how to author rules utilizing fusion features based on isolated
snippets from the fusion guide.</span></font></p>
<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">Can
anyone point me to some reasources for learning rule authoring, especially for
taking advantage of the fusion features.</span></font></p>
