[rules-users] using Drools global variables inside operator timer(int: s)
Hi,
I want a global variable inside a timer instead of hard coding.
-
ksession.setGlobal( "timeout", new Integer(10));
---
*
Improper (not working) rule: *
global Integer timeout;
rule "tmeout case"
timer( int: timeout.intValue() s )
when
$request : EventRecord(eventType == "EVENT_REGISTER", user ==
"katta") from entry-point "AggStream"
and not (EventRecord( eventType == "EVENT_RESPONSE", ", user ==
"katta", this after[ 0s, 10s ] $request ) from entry-point "AggStream")
then
System.out.println("-- timeout for user : "+ $request.getUser() );
end
--
This new rule doesn't give any error but it is giving unexpected result.
For example if a fire only one EventRecord(eventType == "EVENT_REGISTER",
user == "katta") into the working memory, then after 10seconds I should get
timeout as per my requirement.
But for the above rule as soon as I fire the EventRecord it is giving as
timeout.
Please help me in this regard

Re: [rules-users] Drools variables
what about the paramaters of timer( int: ? )
?
timer(int : 10s) --> is working properly
but timer(int : s ) --> not working
-
working Rule:
rule "tmeout case"
timer( int: 10s )
when
$request : EventRecord(eventType == "EVENT_REGISTER", user ==
"katta") from entry-point "AggStream"
and not (EventRecord( eventType == "EVENT_RESPONSE", ", user ==
"katta", this after[ 0s, 10s ] $request ) from entry-point "AggStream")
then
System.out.println("-- timeout for user : "+ $request.getUser() );
end

Now I want to replace value "10" given in the above rule with a global
variable.

Re: [rules-users] please provide a rule for events timeout cases
Hi,
Now time out is working fine.
But facing issues for correlating success and failure events which doesnot
have unique id. I want to correlate an event request followed by its
immediate event response.
Ex: Consider the events in below order
EventRecord( type=EventRequest, user="katta" )
EventRecord( type=EventResponseFailure, user="katta" )
EventRecord( type=EventRequest, user="katta" )
EventRecord( type=EventResponseSuccess, user="katta" )
Rules:
rule event_success_case
when
$req : EventRecord( type=EventRequest, user="katta" )
and EventRecord( type=EventResponseSuccess, user="katta", this after[0s,
10s] $req )
then
System.out.println("Success case for user " + $req.getUser());
retract($req);
end
rule event_failure_case
when
$req : EventRecord( type=EventRequest, user="katta" )
and EventRecord( type=EventResponseFailure, user="katta", this after[0s,
10s] $req )
then
System.out.println("Failed case for user " + $req.getUser());
retract($req);
end
In the above example I don't have any unique identity to correlate request
and response. I need to correlate only based on events order.
In the above example events order is EventRequest --> EventResponseFailure
and then EventRequest --> EventResponseSuccess. So my expected output is:
Failed case for user katta
Success case for user katta
But I am getting below response:
Success case for user katta
Success case for user katta
First EventRequest and second EventRequest are correlating with second
response EventResponseSuccess as this response is within 0 to 10sec for both
events.
Note: I am getting expected result only when I send few events. If I insert
around 50 events at time into Working Memory, I face this kind of unexpected
result.
I need to work on live trafic, where I receive hurends of messages per
second.

Re: [rules-users] please provide a rule for events timeout cases
Hi, Thanks for the response.. This is working fine.. But I have a query on the rule: rule no_response timer( int: 10s ) when EventRecord( type=EventRequest, id=1 ) not EventRecord( type=EventResponse, id=1 ) In general timer means executing a thread for every specified time period interval. But in our case, one time would be enough for an event. In the above rule my query is - after timeout case (i.e., firstime 10 seconds from the EventRequest), timer thread will be closed or will it be still running? Second Query is: Consider the below Success rule: rule event_success_case when EventRecord( type=EventRequest, id=1 ) and EventRecord( type=EventResponse, id=1 ) With "no_response" rule, for every EventRequest there is a timer thread running for every 10Sec. Second rule "event_success_case" looks for its EventResponse. Suppose with in 10 seconds there is a response then "event_success_case" rule is run. Now I would like to close the timer thread because it uses my system memory. Please let me know if this is possible. -- View this message in context: http://drools.46999.n3.nabble.com/please-provide-a-rule-for-events-timeout-cases-tp3907955p3914382.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] please provide a rule for events timeout cases
Hi, For the first time even I have tried the same. But it doesn't work. I need to correlate the events on live. I am using fire rule until hault (ksession.fireUntilHalt()). EventRecord(type=EventRequest, id=1) not EventRecord(type=EventResponse, id=1, this after [1s,10s]) This rule doesn't work because when EventRecord(type=EventRequest, id=1) hit working memory, this rule also looks for EventRecord(type=EventResponse, id=1). As the EventResponse doesn't the working memory, "not" logic become true and executing the R.H.S part as soon as EventRequest arrives. This is not waiting for 10seconds time interval. -- View this message in context: http://drools.46999.n3.nabble.com/please-provide-a-rule-for-events-timeout-cases-tp3907955p3914047.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] please provide a rule for events timeout cases
Hi, I would like to write a rule for events timeout case. Consider the events EventRecord(type=EventRequest, id=1) and EventRecord(type=EventResponse, id=1). I have written rules (in .drl file) for correlting the event request with event response. Now I would like to write timeout case. Suppose EventRecord(type=EventRequest, id=2) is not followed by its response. If we doesn't recieve response within 10 seconds, then it is considered as timeout case. I tried to use timers but it doen't work as it is not allowing me write inside when (LHS) pattern. Is there any other way to find timeout cases? -- View this message in context: http://drools.46999.n3.nabble.com/please-provide-a-rule-for-events-timeout-cases-tp3907955p3907955.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] is there any 'followed by' in Drools as we have in esper
Actually I have tried this operator "after", but doesn't work properly as the events are inserted into working memory one by one within fraction of seconds.
