[rules-users] Problem implementing multiple evals
When I'm trying to execute multiple evals I'm getting errors. Below is what
I'm trying to do
MyEvent(prop1="XYZ") over window:time(1m) from entry-point
MyStream
or
(MyEvent() over window:time(1m) from entry-point MyStream
and
Number($i1 : doubleValue)
from accumulate(
MyEvent(
prop1 == "CONNECT",
prop2 == 3,
eval((prop3 matches ("match
"+getFirstNameRegex()+"
Connect")) == true)
) over window:time(1m) from entry-point MyStream,
count()
)
and
eval($i1 > getNodeCount()*0.35))
or
(MyEvent() over window:time(1m) from entry-point MyStream
and
Number($i2 : doubleValue)
from accumulate(
MyEvent(
prop1 matches "(second|Third{1}_CONNECT",
prop2 == 1,
eval((prop3 matches
("MatchOne|MatchTwo){1}::"+getMMSCNameRegex()+", failure")) == true)
) over window:time(1m) from entry-point MyStream,
count()
)
and
eval($i2 > getConnectionCount()*0.4))
or
(MyEvent() over window:time(1m) from entry-point MyStream
and
Number($i3 : doubleValue)
from accumulate(
MyEvent(
prop1 matches "(E1|E2){1}_CONNECT",
prop2 == 3,
eval((prop3 matches ("REPT (one|five|seven){1}::
"+getServerID()+" is down")) == true)
) over window:time(1m) from entry-point MyStream,
count()
)
and
eval($i3 > getThirdNodeCount()*0.5))
When I'm trying to execute the above LHS I get
org.drools.rule.InvalidPatternException: Required Declarations not bound:
'$i1'.
I even tried using below approach
AlertReceivedEvent() over window:time(1m) from entry-point
NotificationStream
$I1 : Double() from getIsgNodeCount()
Number(doubleValue > $I1) from accumulate(
AlertReceivedEvent(
entity == "NPMMS_NE_CONNECT",
probableCause == 3,
eval((specificProblems matches ("REPT ISG
NPMMS::Unable to connect to "+getPxmmsNameRegex()+" node: PXMMS")) ==
true)
) over window:time(1m) from entry-point
NotificationStream, count()
)
But when I'm placing parentheses () around it, it throws exception stating
mismatched input '$I1' expecting ')' in rule. For now I'd placed these
3
statements in separate rules. Can anyone please help me solving it? Thanks
in advance.
