[rules-users] Unpredicatable output with Temporal rule
Requirement:
To identify those tickets with "critical" severity which occurs after
2minutes but before 5minutes of a ticket with severity 'warning', provided
both are of different application name.
This rule though not meaningful, is considered to understand the temporal
operator.
This is the rule:
declare OMNewTicket
@role( event )
@expires (10m)
end
rule "Sample Temporal"
salience 10
no-loop true
when
$ticket : OMNewTicket(severity == "warning", $appName : appName)
$ticket1 : OMNewTicket(this after[2m, 5m] $ticket, severity == "critical",
appName != $appName)
then
String $s = "";
String $s1 = "";
if ( $ticket != null) {
$s = formatDate($ticket.getReceivingTime());
}
if ( $ticket1 != null ) {
$s1 = formatDate($ticket1.getReceivingTime());
}
drools.getWorkingMemory().setGlobal( "output", "found");
drools.getWorkingMemory().setGlobal( "output1", $s);
drools.getWorkingMemory().setGlobal( "output2", $s1);
end
function String formatDate( String inputDate ) {
try {
DateFormat formatter = new SimpleDateFormat("MM/dd/yy:hh:mm:aaa");
Date date = (Date)formatter.parse(inputDate);
return date.toString();
} catch (ParseException e) {
System.out.println("Exception :"+e);
return null;
}
}

Output:
Status Time of Ticket Timestamp of Ticket1 Time (Clock)
found Sat Oct 25 10:00:00 Sat Oct 25 10:05:00 Sat Oct 25
10:05:00
found Sat Oct 25 10:00:00 Sat Oct 25 10:08:00 Sat Oct 25
10:08:00
found Sat Oct 25 10:04:00 Sat Oct 25 10:10:00 Sat Oct 25
10:10:00
found Thu Dec 11 03:25:00 Thu Dec 11 03:34:00 Thu Dec 11
03:34:00
Here Time of Ticket is output1 from rule and Timestamp of Ticket1 is
output2 of the consequence.
Problem :
The output 'found Thu Dec 11 03:25:00 Thu Dec 11 03:34:00
Thu Dec 11 03:34:00 ' is not satisfying the rule condition.
After first three output, there are no tuples matching the criteria
mentioned. Unable to predict the occurence of this in the output.
May I know what i miss here?
