GSLB_Monitor (object)¶

Declares a monitor that verifies the availability and/or performance status of a particular protocol, service, or application

Properties (* = required):

name	type(s)	default	allowed values	description
/*/
class*	string		“GSLB_Monitor”
ignoreDownResponseEnabled	boolean	false	true, false	Specifies whether the monitor immediately marks an object down when it receives a down response. If enabled, the monitor ignores the down response for the duration of timeout. The default is false (disabled)
interval	integer	30	0 - 86399	Specifies, in seconds, the frequency at which the system issues the monitor check when either the resource is down or the status of the resource is unknown
label	string		“^[^x00-x1fx22#&<>?x5b-x5d`x7f]$”	Optional friendly name for this object. Allows 0-64 chars, excluding a few likely to cause trouble with string searching, JS, TCL, or HTML
monitorType*	string		“http”, “https”, “gateway-icmp”, “tcp”, “udp”, “external”	Specifies the type of monitor
probeTimeout	integer	5	0 - ∞	Specifies the number of seconds after which the system times out the probe request to the system
remark	string		“^[^x00-x1fx22x5cx7f]*$”	Arbitrary (brief) text pertaining to this object. Allows 0-64 chars, excluding only control characters, double-quote, and backslash. This is permissive enough that you should worry about XSS attacks
target	string	“:”		Specifies the IP address and service port of the resource that is the destination of this monitor. Format is ip:port
timeout	integer	120	0 - 86400	Specifies the number of seconds the target has in which to respond to the monitor request

GSLB_Monitor_External (object)¶

Additional Monitor class properties available when monitorType = external

Properties (* = required):

name	type(s)	default	allowed values	description
/*/
arguments	string	“”		Arguments to specified external monitor (will be backquote-expanded)
environmentVariables	object	{}		Specifies user defined command line parameters that the external program requires.
expand	boolean	true	true, false	If true (default), expand backquoted variables in script
pathname	string			Tmsh object path name of an imported existing external monitor (e.g. /Common/arg_example)
script				Bash(1) script which implements external monitor,String value optionally in base64 or from URL or BIG-IP AS3 pointer

Specifies user defined command line parameters that the external program requires.

Default: {}

Additional Monitor class properties available when monitorType = http

Properties (* = required):

name	type(s)	default	allowed values	description
/*/
receive	string	“HTTP/1.”		Specifies the text string that the monitor looks for in the returned resource. If you do not specify a value for both the send and receive options, the monitor performs a simple service check and connect only
receiveStatusCodes	array			Specifies the status codes that the monitor looks for in the returned resource
reverseEnabled	boolean	false	true, false	When enabled, a successful check marks the monitored object down instead of up. You can use the Reverse mode only if you configure both the send and receive options
send	string	“HEAD / HTTP/1.0rnrn”		Specifies the text string that the monitor sends to the target object. If you do not specify a value for both the send and receive options, the monitor performs a simple service check and connect only
transparent	boolean	false	true, false	Enables monitoring of pool members through firewalls. The default value is false (disabled)

clientCertificate	string			BIG-IP AS3 pointer to client Certificate declaration, for TLS authentication (optional)
receive	string	“HTTP/1.”		Specifies the text string that the monitor looks for in the returned resource. If you do not specify a value for both the send and receive options, the monitor performs a simple service check and connect only
