DESCRIPTION
You can use the wmi component to configure a custom monitor, or you can use the default WMI monitor that the
Global Traffic Manager provides. This type of monitor checks the performance of a pool, pool member, or
virtual server that is running the WMI data collection agent, and then dynamically load balances traffic
accordingly.
EXAMPLES
create wmi my_wmi defaults-from wmi
Creates a monitor named my_wmi that inherits properties from the default WMI monitor.
list wmi
Displays the properties of all of the WMI 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.
command
Specifies the command that the system uses to obtain the metrics from the resource. See the documentation
for this resource for information on available commands.
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The
default value is wmi.
description
User defined description.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
ignore-down-response
Specifies whether the monitor ignores a down response from the system it is monitoring. The default value
is disabled.
interval
Specifies the frequency at which the system issues the monitor check. The default value is 30 seconds.
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
LoadPercentage, DiskUsage, PhysicalMemoryUsage:1.5, VirtualMemoryUsage:2.0.
name Specifies a unique name for the component. This option is required for the commands create, delete, and
modify.
partition
Displays the administrative partition within which the component resides.
password
Specifies the password if the monitored target requires authentication. The default value is none.
post Specifies the mechanism that the monitor uses for posting. The default value is RespFormat=HTML. You
cannot change the post format for WMI monitors.
probe-timeout
Specifies the number of seconds after which the BIG-IP(r) system times out the probe request to the BIG-
IP system. The default value is 5 seconds.
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.
timeout
Specifies the number of seconds the target has in which to respond to the monitor request. The default
value is 120 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.
url Specifies the URL that the monitor uses. The default value is /scripts/f5Isapi.dll.
username
Specifies the user name if the monitored target requires authentication. The default value is none.
