Name:
Enter an appropriate name for the filter.
Number of Messages:
If the Enterprise Gateway receives more than this number of messages during the
time interval specified in the field below, the filter fails. Otherwise,
the filter passes.
Time Period:
If the Enterprise Gateway receives more than the number of messages specified in
the above field in the time interval specified here, the filter fails.
Otherwise, the filter passes. The time period depends on the value
selected below (seconds, minutes, hours, days, or weeks). For example, if
you enter 10 as the Time Period and select
Minutes from the Time Period Unit drop-down
list below, the time period lasts 10 minutes.
Time Period Unit:
The unit that the time period is measured in must be selected from the following
options: Second , Minute , Hour , Day ,
or Week . The value selected together with that entered above determines
the time period.
Alternatively, you can specify the time period unit using a property to represent the
value of a message attribute, which is looked up and expanded to a value at runtime.
Use the following syntax to specify the property:
${name_of_message_attribute} . Allowed values are
Second , Minute , Hour , Day , or
Week .
Note:
When one of Second , Minute , or Hour is specified,
you do not need to configure the Time Period Commences on Hour/Day fields.
The time period commences when a message is received and lasts for the time period (for
example, 10 minutes). When this time period is up, the message count is reset, and the
counter starts again when another message is received. The sections that follow explain
how the time period is measured when the Time Period Unit is set to
Day or Week .
Time Period Commences on Hour:
This field must be configured if you select either Day or
Week as the Time Period Unit above. For
example, if you select Day above and enter 00:00
in this field, this means that only the specified number of messages can
be received in a one day period starting from midnight tonight until midnight
the next day.
Time Period Commences on Day:
This field must only be configured if you select Week as the
Time Period Unit above. For example, if you select
Week and 00:00 in the fields above, and enter
Sunday , this means that the time period commences next Sunday
at midnight and will lasts for one week exactly. The time period is reset
on midnight of the next Sunday.
