I don't have startTimestamp and endTimestamp fields. I assume these fields

Computationally, during the evaluation of the temporal operators.
If I need to define them myself, what is the advantage of defining
timestamp and duration attributes?
Why would you want to do this? (My advice to replace the temporal
operators by the equivalent expressions was meant as a debugging aid,
to show you where the problem with this constraint is.)
I'll try to organize the fourth question:
I can't answer your question - it's impossible to tell what might
happen without the code for CorrelatedEvent.java. For reproducing
this, also the code for Log.java should be available. A couple of
remarks:
- Why do you use this complex declare?
@timestamp( timestamp ) @duration( duration )
is sufficient.
- Why do you use a Map and not simple fields? The DRL code is very confusing.
- Why do you use two accumulate CE's when the set of matching
elements is the same in both?

I am trying to identify a port scan event:
Basic event is connection log. For each combination
of source_ip and destination_ip, detect a port scan event,
if over 5 seconds there were more than 2 connection logs with
different ports .
The event will stay open for 10 seconds and an update will be
sent for any new port detected. Every update will contain the count of
connection logs combining it and their id (marker).
This is my drl file:
package test;
import correlation.impl.drools.Log
import correlation.impl.drools.CorrelatedEvent
global correlation.server.EventsHandler externalEventsHandler;
declare Log
@role( event)
end
declare CorrelatedEvent
@role( event)
@timestamp( getTimestamp().getTime() )
@expires( 10s )
@duration( getDuration() )
end
// this rule will create a Port Scan event if none exist for this group-by
values
rule Create Port Scan Event
dialect java
no-loop
when
$log : Log() from entry-point Log stream //get all the logs in the last
5 seconds
accumulate( Log( this after[0s,5s] $log, fieldsMap.get(src) ==
$log.fieldsMap.get(src) , fieldsMap.get(dst) ==
$log.fieldsMap.get(dst), $port : fieldsMap.get(port)) from entry-point
Log stream;
$portSet : collectSet($port);
$portSet.size 2 )
accumulate( Log( this after[0s,5s] $log, fieldsMap.get(src) ==
$log.fieldsMap.get(src) , fieldsMap.get(dst) ==
$log.fieldsMap.get(dst), $marker : fieldsMap.get(marker)) from
entry-point Log stream;
$markerSet : collectSet($marker))
not CorrelatedEvent(getName() == portScan , fieldsMap.get(src) ==
$log.fieldsMap.get(src) , fieldsMap.get(dst) ==
$log.fieldsMap.get(dst))
then
System.out.println(drools.getRule().getName());
CorrelatedEvent $ce = new CorrelatedEvent();
$ce.setName(portScan);
$ce.setEventsHandler(externalEventsHandler);
$ce.setDurationInSec(10);
$ce.fieldsMap.put(src, $log.fieldsMap.get(src));
$ce.fieldsMap.put(dst, $log.fieldsMap.get(dst));
$ce.endUpdate($markerSet);
insert($ce);
end
rule Create Port Scan Event - update
dialect java
no-loop
when
$ce: CorrelatedEvent(getName() == portScan)
accumulate( Log(fieldsMap.get(src) == $ce.fieldsMap.get(src) ,
fieldsMap.get(dst) == $ce.fieldsMap.get(dst) , $port :
fieldsMap.get(port) , this after $ce.getStartTime() , this before
$ce.getEndTime()) from entry-point Log stream;
$portSet : collectSet($port);
$portSet.size 0 )
accumulate( Log(fieldsMap.get(src) == $ce.fieldsMap.get(src) ,
fieldsMap.get(dst) == $ce.fieldsMap.get(dst) , $marker :
fieldsMap.get(marker) , this after $ce.getStartTime() , this before
$ce.getEndTime()) from entry-point Log stream;
$markerSet : collectSet($marker))
then
System.out.println(drools.getRule().getName());
modify( $ce ) {endUpdate($markerSet)}
end
I test it like this:
I insert a connection log and fire the rules every second. I have 25 logs
with the same src and dst, but each has different (serial) port and
marker.
So after 12-13 logs, I expect to identify a new event with another
consecutive 3 logs.
In each rule's RHS, I print the rule fired and the port set of logs
triggering it.
With existing implementation, I see the following output at 14th second:
rule fired: Create Port Scan Event - update
portSet: [10, 7, 6, 5, 4, 9, 8, 11, 12]
rule fired: Create Port Scan Event
portSet: [13, 11, 12]

Dear Drools users,
Apparently it was not caused by the previously mentioned fix.
Sometimes I still had a KnowledgeAgent in my server that doesn't
respond anymore which seems to be caused by a mistake in the DRL file.
I started to investigate the source code of KnowledgeAgentImpl and
KnowledgeBaseImpl and recompiled them to add some prints. Finally I
tracked it until AbstractRuleBase.addPackages.
There is a giant Try-final block and I noticed by adding prints that
it stopped somewhere in the middle. When it does fail, my
KnowledgeAgent stops working completely.
The try-final seemed to be the only place for me where an exception
might be ignored so I added a catch clause.
As a result, the error report of my drl file was nicely printed and my
agent didn't crash:

Re: [rules-users] Exception in thread main java.lang.ClassCastException: org.drools.io.impl.FileSystemResource cannot be cast to org.drools.io.InternalResource
This can happen, if you mix and match wrong versions of jars on your class path.
