Syntax

OPERATIONS:

*   count("group_field", time_in_minut)
*   countSuccess("group_field", time_in_minut)
*   countError("group_field", time_in_minut, "error_code")
*   sum("group_field", time_in_minut)
*   sumSuccess("group_field", time_in_minut)
*   sumError(("group_field", time_in_minut, "error_code")
*   unique(("group_field", "by_field")
*   in(("field", "first", "second", ...)
*   inWhiteList("field")
*   inBlackList("field")
*   like("field", "regexp_in_java_style")
*   equalsCountry()

RESULTS:

*   accept 
*   3ds
*   decline
*   notify

EXAMPLES:

Simple:

rule: 3 > 2 AND 1 = 1
-> accept;

Black list check:

rule: inBlackList("email")
-> notify;

Counts check:

rule: (count("ip", 1444) >= 10 OR countSuccess("email", 1444) > 5)
        AND countError("fingerprint", 1444, "error_code") > 5
-> notify;

Unique count emails for ip:

rule: unique("email", "ip") < 4
-> decline;

Combined check:

rule: 3 > 2 AND 1 > 1
-> decline;

rule: count("email", 10) <= 10 AND count("ip", 1444) = 10
-> 3ds;
