Can you extract and post the rule called "MyRule_01"?
I'd also check the class MyEnum.. is it an enum as the name
might imply? Is it implementing Comparable
and/or trying to redefine the method compareTo?

Re: [rules-users] Implementation of my use case - what am I doing wrong?

2013-09-17 Thread Elran Dvir

Thanks for the quick response.

I have some more questions:

1. As I understand it, the timestamp attribute should be long type 
representing the milliseconds since January 1, 1970, 00:00:00 GMT. Am I right?
2. As I understand it, the duration attribute  should be in 
milliseconds. I fixed it accordingly. Am I right?
3. When I replaced "(this meets $ce || this during $ce || this metby 
$ce)" with "$ce.startTimestamp <= startTimestamp , endTimestamp <= 
$ce.endTimestamp"
I got the following drools compile exceptions:

Unable to Analyse Expression $ce.startTimestamp:
[Error: unable to resolve method using strict-mode: 
com.checkpoint.correlation.impl.drools.CorrelatedEvent.startTimestamp()]
[Near : {... $ce.startTimestamp }]
^
[Line: 61, Column: 28] : [Rule name='Create Port Scan Event - 
update']

Unable to Analyse Expression $ce.startTimestamp <= 
startTimestamp:

update']

Unable to Analyse Expression $ce.startTimestamp:
[Error: unable to resolve method using strict-mode: 
com.checkpoint.correlation.impl.drools.CorrelatedEvent.startTimestamp()]
[Near : {... $ce.startTimestamp }]

   Why?
4. I tested  my working implementation of temporal relation in rule 
"Create Port Scan Event - update" ("this after $ce.getStartTime() , this before 
$ce.getEndTime()") .
I inserted a connection log and fired the rules every second. I 
have 25 logs with the same "src" and "dst", but each has different (serial) 
"port" and "marker".
I print the rule fired and the port set of logs triggering it.
I got this behavior: for the second and third "rounds" (after 10 
seconds and 20 seconds), the first rule process logs already processed by the 
second rule.

   Output example:
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]

   I understand this behavior, so I changed the order of conditions in 
the LHS of the first rule ("not CorrelatedEvent..." to be the second):
$log : CpLog() //get all the logs in the last 5 seconds
not CorrelatedEvent(getName() == "portScan" , 
fieldsMap.get("src") == $log.fieldsMap.get("src") , fieldsMap.get("dst") == 
$log.fieldsMap.get("dst"))
accumulate( CpLog( this after[0s,5s] $log, 
fieldsMap.get("src") == $log.fieldsMap.get("src") , fieldsMap.get("dst") == 
$log.fieldsMap.get("dst"), $port : fieldsMap.get("port"));
$portSet : collectSet($port);
$portSet.size > 2 )
accumulate( CpLog( this after[0s,5s] $log, fieldsMap.get("src") 
== $log.fieldsMap.get("src") , fieldsMap.get("dst") == 
$log.fieldsMap.get("dst"), $marker : fieldsMap.get("marker"));
$markerSet : collectSet($marker))

   But then I get the following output for the first 4 logs:
rule fired: Create Port Scan Event
portSet: []

rule fired: Create Port Scan Event - update
portSet: [13, 11, 12]

   Why is that? Where the first 3 events disappeared? How "portSet" is 
empty with the condition  $portSet.size > 2? 

Thanks a lot.

Yes. No. An entry point is just an additional attribute added "on the fly",

[rules-users] gives error while retracting an object

2013-09-17 Thread Ganesh

Hi Team,

I am using drools-guvnor 5.4 version and designer 2.1 version,

I am calling an drools object from web service
While retracting an object I am getting
classCastException,"*java.lang.boolean cannot be cast to
org.drools.spi.activation* "

I am using session.retract(droolsobject);-Every time I got the error in this
line

This issue rise very often,


I think this issue is due to increase on load on object ,As I found this is
the reason while I search in INTERNET

Can you please tell me how to solve this


Regards
Ganesh N  Neelekani

Not necessarily. The interpretation of this long value is up to you -
it could mean days since the foundation of Rome (753 BC).

Use the same unit as the timestamp.

Sorry, you've lost me here. I can't see what's going on from this
unorganized set of snippets - and please don't suppose that people
keep old mails or have the time to dig in the archives.

Re: [rules-users] Implementation of my use case - what am I doing wrong?

2013-09-17 Thread Elran Dvir

Thanks again.

I don't have startTimestamp and endTimestamp fields. I assume these fields are 
created on runtime bases on duration and timestamp attributes. Isn't it?
If I need to define them myself, what is the advantage of defining  timestamp 
and duration attributes?

I'll try to organize the fourth question:
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]

As we can see, the first rule processes logs already processed by the second 
rule.
After examining the first rule, I understood this behavior. 
I decided to change the order of conditions in the LHS of the first rule by 
moving "not CorrelatedEvent..." to be the second condition. 
But then I get the following output after the first 4 logs:

rule fired: Create Port Scan Event
portSet: []

rule fired: Create Port Scan Event - update
portSet: [4]

Why is that? Where the first 3 events "disappeared"? How $portSet is empty with 
the condition  $portSet.size > 2? 

Thanks a lot.

[rules-users] using ruleflow group and agenda group together

2013-09-17 Thread ashish6276

HI

 In my POC I Created 4 ruleflow groups. Each group has rules which are from
2 different agenda groups. if 2 rules which are in same ruleflowgroup have
everything similar in when condition except agendagroup the flow is stoping
there. If i am making the when condition different for rules in one ruleflow
group then end to end flow is working fine.what can be the reason for this.

It reminds me of a bug, could you try 5.5.0.Final or 5.6.0-SNAPSHOT?
Even better, could you post a reproducer test case for your issue?

Re: [rules-users] No errors thrown from KnowledgeAgent

2013-09-17 Thread De Rooms Brecht


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:

Maybe there is a reason for this missing catch so I am not sure whether 
I fixed it and broke something else ( eg. maybe I should undo a part of 
the operations before I continue).

Is there anyone who knows this code and who can help me?

Extra information:
- I use Drools 5.5 from the Maven repository.
- my agent configuration:
agentConf.setProperty("drools.agent.newInstance", "false");
agentConf.setProperty("drools.agent.useKBaseClassLoaderForCompiling", 
"true");



Kind Regards,
De Rooms Brecht

The bug was caused by one of the InputStreams that was not closed

I think my issues are solved now.

Thanks for looking into this.

Hello David and thanks for responding.
I know it supports these event listeners and I use them. In my 
program, I have two knowledge agents and the first one 
(preprocessing) will read the file, preprocess a DRL and then write a 
second modified DRL file in a folder that is monitored by the second 
one. When I modify the original DRL file *(1.* in prints below*)* 
monitored by the preprocessing agent, everything works fine and the 
rule is triggered*(**2.)*. However, when I delete a file *(**3.)*, 
the knowledgeAgent just blocks after AfterChangeSetAppliedEvent and 
does not do anything anymore.. If I send new data in the 
knowledgeAgent it does not react anymore.


I would expect to get a stacktrace of what went wrong but I do not 
get any info besides of the systemeventlistener or 
knowledgeagentlistener. Is there any way I can get a stacktrace?

Kind Regards,
De Rooms Brecht

Thanks.

JIRA Project "GUVNOR" would have been better, as requested. It's likely to
be missed in "GUVNORSOA".

[rules-users] rule flow execution.

2013-09-17 Thread ashish6276

Hi

   My ruleflowgroup contains 2 rules which have different agendagroup
defined for them. If i make when condition of both the rules same the flow
execution stops here only instead of going to next ruleflowgroup. I am not
understanding why this is happening.
