Rule Status - Field Help
Configuration Settings
If applicable, edit any of the values on the Rule Status panel and
click Update Configuration.
- Begin range
- The lower value in the range used to determine whether or not the rule
is true. The kind of value and its default depends on the type of rule:
- ip address - the address of the client as either a symbolic name or in
dotted-decimal format. The default value is 0.0.0.0.
- time of day - an integer. The default value is 0, representing midnight.
- total connections - an integer. The default value is 0.
- active connections - an integer. The default value is 0.
- client port - an integer. The default value is 0.
- reserved bandwidth - an integer. The default value is 0.
- End range
- The higher value in the range used to determine whether or not the rule
is true. The kind of value and its default depends on the type of rule:
- ip address - the address of the client as either a symbolic name or in
dotted-decimal format. The default value is 255.255.255.255
- time of day - an integer. The default value is 24, representing midnight.
- total connections - an integer. The default value is 2 to the 32nd power
minus 1.
- active connections - an integer. The default value is 2 to the 32nd power
minus 1.
- client port - an integer. The default value is 65535.
- reserved bandwidth - an integer. The default value is 2 to the 32nd power
minus 1.
- Priority (optional)
- An integer representing the order in which rules are reviewed. If no priority
is given to the first rule you set, by default it will be given a priority value of 1 and evaluated first.
The next rule will then be given a priority value of 11 and evaluated second, (last priority value + 10, in
this case 1 + 10), third rule = 21, fourth rule = 31, and so forth. The rules are evaluated in numerical
order, lower numbers taking precedence over higher ones.
- Affinity type
- Rule-based affinity is valid only for ports with content-based routing enabled. If the port already
has affinity, such as client IP or SSL ID specified, then affinity can not be set at the rule level and
vice versa. Choose the type of affinity you want on this rule. Choices are:
- No rule affinity - default option, means there is no affinity associated with this rule.
- Passive cookie affinity - allows you to load-balance web traffic with affinity to the same
server, based on self-identifying cookies generated by the servers. This is used in conjunction with the
"Cookie Name" on the rule along with the "Cookie Value" on the server.
- URI affinity - allows you to load-balance Web traffic to caching proxy servers which allow
unique content to be cached on each individual server. This is intended for scenarios where CBR is balancing
caching proxies, in order to minimize the amount of necessary caching.
- Level to evaluate
- Valid only for Total Connections, Active Connections and Reserved Bandwidth. Choose
between evaluating all of the servers on the port or only the servers on the rule.
- Cookie name
- An arbitrary name set by the administrator, that acts as an identifier to
Network Dispatcher. The cookie name, along with the cookie value, acts as an
identifier to Network Dispatcher allowing Network Dispatcher to send subsequent
requests of a website to the same server machine.
Current Statistics
- Name
- The name you chose for the rule. This name can contain any alphanumeric character,
underscore, hyphen, or period. It may be from 1 to 20 characters and cannot contain any
blanks.
- Rule type
- The type of the rule. Possible types are:
- ip address - based on the client IP address.
- time of day - based on the time of day.
- total connections - based on the number of connections per second for the
port.
- active connections - based on the number of active connections total for
the port.
- client port - based on the client port.
- type of service - based on the type of service.
- reserved bandwidth - an integer. Based on the number of bytes per second being
delivered by a set of servers.
- shared bandwidth - an integer. Based on the amount of bandwidth to share at
either the cluster or executor level. If the value is 0, then bandwidth cannot be
shared.
- content - a regular expression that will be compared to the client requested URLs.
- always true - will always be true. (Think of it as an else statement in
programming logic.)
- Times fired
- The number of times this rule has fired either since it was added or since the last
time the executor was restarted.
- Pattern
- Only applicable if you selected Content for the rule type. This is the search string
you want to use, on the rule, with the following restrictions:
- no spaces
- special characters: (unless you precede the character with a "\")
'*' : wildcard (matches 0 to x of any character)
'(' : used for logic grouping
')' : used for logic grouping
'&' : logical AND
'|' : logical OR
'!' : logical NOT
- reserved keywords (always followed by '='):
Method : used by the HTTP protocol, in a translation,
to retrieve a request. For example, GET, POST and
so forth.
URI : path of the URL request
Version : specific version of the request, either
HTTP/1.0 or HTTP/1.1
Host : value from the host: header
Note:optional in HTTP/1.0 protocols
[key] : any valid HTTP header name that Dispatcher
can search for. For example, User-Agent,
Connection, referer, and so forth.
Examples: A browser targeting http://www.company.com/path/webpage.htm might result in values such as the following:
Method=GET
URI=/path/webpage.htm
Version=HTTP/1.1
Host=www.company.com
Connection=Keep-Alive
For more information regarding pattern syntax, as well as scenarios, please see the Network Dispatcher
Administration Guide, which you can download or view from the
Websphere Edge Server library page.
- Total active connections
- The current total number of active connections for this port. Applicable to the total connections,
active connections and reserved bandwidth rules only.
- Connections per second
- The current number of connections per second for this port. Applicable to the total connections,
active connections and reserved bandwidth rules only.
- KBytes transferred per second
- The number of kilobytes being transferred per second on this port.

Lists
- List of Servers
- Shows the addresses of servers currently associated with the rule.
