Hi all,
I am new to drools and I'm trying to understand whether the following use case is
supported - any help on the following will be greatly appreciated:
I would like to create a new event based on multiple events (all of the same type meeting
a set of conditions) occurring over a given period of time T1.
For each combination of values for fieldA and fieldB, a new group of event candidates
should be opened (fieldA and fieldB are group by fields. Each combination of values of
these fields, should be treated separately).
The event should be created when at least X events occurred over the period. Count the
events based on unique values of fieldC and fieldD (for a given combination of fieldA and
fieldB, if you notice an event with already existing values of the combination of fieldC
and fieldD, it should not be counted).
If all conditions described above are met, create the desired new event. The new event
will stay open for duration of T2, and update will be sent for it every T3.
Aside from the above, I need an aggregation function (besides count) of
"collect" : in the new event the value of fieldE will be the collection of
(preferably distinct) values of fieldE in originating events.
Example:
Port scan event - the basic event is connection. For each combination of source_ip and
destination_ip (group by fields), detect a port scan event if over a minute (T1) there
more than 20 (X) events with different ports (unique field).
The event will stay open for 10 minutes (T2) and an update will be sent every 1 minute
(T3). Every update will contain the count of events, source_ip, destination_ip and
collection of services.
Thanks a lot.
4:40 p.m.
You should look into the Expert and Fusion manuals, especially:
Expert for the syntax and most features,
sliding "window" in Fusion,
"timer" in Expert,
"accumulate" and "from collect" in Expert.
Your text is a little too hazy to try and concoct a set of rules
demonstrating what needs to be done - they may be off in more than one
respect.

What should happen if the last T1-interval of T2 fulfills the

Hi,
I am prepared to write as many rule sets needed for each required use case.
I'll try to clarify the use case:
If an event meeting a set of conditions is detected (in the example, any connection
event), a new (sliding) window of events candidates will be opened for T1.
The window will be opened based on "group by fields" - any event with the same
group by fields' within the time frame values should go the matching window.
So, at any given time there will be as many windows as there were unique combination of
"group by" fields values in last T1.
For any window, the events will be counted only for unique values of predefined unique
fields.
Maybe the semantics of creation of new event was confusing.
Instead of creating new event, let's simply it and say I want to print the data.
Once the count threshold (X) is reached, I would like to print the data of originating
events and extend the window with time of T2.
I would like to print an update of the data of all originating events arrived so far every
T3 (this feature is the least important. I can just print the summary of all accumulated
data in the end of T2).
Is this behavior supported?
I hope it's clearer now.
If needed, I will be happy to elaborate.
Thanks a lot.

I guess it's clear enough now. Once more, I'm sure that all the
required features are available; even if there were no sliding window
it would be possible to work around that. For keeping track of the
state w.r.t. an open group by fields you'll have to insert an
auxiliary fact and use that as a starting point for monitoring the T2
period. Timers will help to do the T3 interval-spaced operations.

Thanks for the really quick response.
I hope I am not asking too much, but can you or anyone else please write my example in
Drools syntax?
It will help me a lot to see an example, so I can understand how all drools excellent
features may be combined to address my use case.
Thanks a lot.
