DESCRIPTION
You can use the real-server component to configure a custom monitor, or you can use the default RealServer
monitor that the Local Traffic Manager provides. This type of monitor checks the performance of a pool, pool
member, or virtual server that is running the RealServer data collection agent, and then dynamically load
balances traffic accordingly.
EXAMPLES
create real-server my_real-server defaults-from real_server
Creates a monitor named my_real-server that inherits properties from the default RealServer monitor.
list real-server
Displays the properties of all of the RealServer monitors.
OPTIONS
agent
Displays the agent for the monitor. The default agent is Mozilla/4.0 (compatible: MSIE 5.0; Windows NT).
You cannot modify the agent.
app-service
Specifies the name of the application service to which the monitor belongs. The default value is none.
Note: If the strict-updates option is enabled on the application service that owns the object, you cannot
modify or delete the monitor. Only the application service can modify or delete the monitor.
command
Displays the command that the system uses to obtain the metrics from the resource. See the documentation
for this resource for information on available commands. You cannot modify the command.
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The
default value is real-server.
description
User defined description.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
interval
Specifies the frequency at which the system issues the monitor check. The default value is 5 seconds.
name Specifies a unique name for the component. This option is required for the commands create, delete, and
modify.
method
Displays the GET method. You cannot modify the method.
metrics
Specifies the performance metrics that the commands collect from the target. The default value is
ServerBandwidth:1.5, CPUPercentUsage, MemoryUsage, TotalClientCount.
partition
Displays the administrative partition within which the component resides.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at
sign (@[regular expression]) to indicate that the identifier is a regular expression. See help regex for
a description of regular expression syntax.
time-until-up
Specifies the amount of time, in seconds, after the first successful response before a node is marked up.
A value of 0 (zero) causes a node to be marked up immediately after a valid response is received from the
node. The default value is 0 (zero).
timeout
Specifies the number of seconds the target has in which to respond to the monitor request. The default
value is 16 seconds.
If the target responds within the set time period, it is considered up. If the target does not respond
within the set time period, it is considered down. Also, if the target responds with a RESET packet, the
system immediately flags the target as down without waiting for the timeout interval to expire.
