DESCRIPTION
You can use the gateway-icmp component to configure a custom monitor, or you can use the default Gateway ICMP monitor that
the Global Traffic Manager provides. You can use a Gateway ICMP type of monitor for a virtual server, a server (that is,
all of the virtuals on a specified server), a pool member, a pool (that is, all of the pool members of a specified pool),
or a link.
EXAMPLES
create gateway-icmp my_imcp defaults-from gateway_icmp
Creates a monitor named my_icmp that inherits properties from the default Gateway ICMP monitor.
list gateway-icmp
Displays the properties of all of the Gateway ICMP monitors.
OPTIONS
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The default value is
gateway_icmp.
description
User defined description.
destination
Specifies the IP address and service port of the resource that is the destination of this monitor. The default value
is *:*.
Possible values are:
*:* Specifies to perform a health check on the IP address and port supplied by a pool member.
*:port
Specifies to perform a health check on the server with the IP address supplied by the pool member and the port
you specify.
IP address:port
Specifies to mark a pool member up or down based on the response of the server at the IP address and port you
specify.
IP address:port (with the transparent option enabled)
Specifies to perform a health check on the server at the IP address and port specified in the monitor, routing
the check through the IP address and port supplied by the pool member. The pool member (the gateway) is marked up
or down accordingly.
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.
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.
probe-attempts
Specifies the number of times the BIG-IP(r) system attempts to probe the host server, after which the BIG-IP system
considers the host server down or unavailable. The default value is 3 attempts.
probe-interval
Specifies the frequency at which the BIG-IP system probes the host server. The default value is 1 second.
probe-timeout
Specifies the number of seconds after which the BIG-IP 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.
transparent
Specifies whether the monitor operates in transparent mode. Monitors in transparent mode can monitor pool members
through firewalls. The default value is disabled.
