ltm rule event RULE INIT

iRule(1)		      BIG-IP TMSH Manual		      iRule(1)



RULE_INIT
       Triggered when an iRule is added or is modified.

DESCRIPTION
       Use this event to initialize global or static variables used within
       iRules.

       Execution

	  This event is triggered under the following conditions;
	    * when an iRule using the event is saved.
	    * when the device starts up.
	    * when the software is restarted.

       Scope

	  The RULE_INIT event is global in scope and is triggered without the
	  context of a virtual server or client to virtual server connection.

       Namespace

	  Variables defined in this event are global across the F5 and share the
	  same namespace with any iRule that uses this event.

       Limitations

	  Global variables modified by an iRule will demote the execution of the
	  virtual to a single processor core. On a BIG-IP with a quad core
	  processor, the virtual will only be able to use one of them. See
	  CMP Compatibility for more details.

Examples
	when RULE_INIT {
	  set ::count 0
	}

	# static namespace is available in 10.0.0+
	when RULE_INIT {
	  set static::debug 1
	}
