NAME
       custom-stat - Provides derived statistics for iStats.

MODULE
       sys application

SYNTAX
       Configure the custom-stat component within the sys application module using the syntax in the following
       sections.

   EDIT
	create custom-stat [key]
	modify custom-stat [key]
	 options:
	   app-service [[string] | none]
	   keyspace [string]
	   formula [string]
	   measure [string]
	edit custom-stat [ [ [key] | [glob] | [regex] ] ... ]
	 options:
	  all-properties

   DISPLAY
	list custom-stat
	list custom-stat [ [ [key] | [glob] | [regex] ] ... ]

   DELETE
	delete custom-stat [key]

DESCRIPTION
       Statistics are derived for objects in the given keyspace based on the given formula, producing the given
       measure.

EXAMPLES
       create sys application custom-stat myKey
	    keyspace sys.application.service
	    measure conns_per_min
	    formula "rate counter conns 60"

       Creates a derived iStat.

OPTIONS
       You can use these options with the custom-stat component:

       app-service
	    Specifies the name of the application service to which the object 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 object. Only the application service can modify or delete the object.

       formula
	    Specifies the first token in the formula indicates the computation to be made. Currently only rates are
	    supported.

	     rate  
		  

	    rate computes the rate of change of the source measure over the last  seconds.
	    This is applicable only to numeric measures. The derived measure is of type gauge.

       keyspace
	    Specifies that a derived iStat will be computed for all objects in the given keyspace for which the
	    formula is computable (the source measure of the correct type exists).

       measure
	    Specifies the name of the derived measure to be created. The type of the derived measure is dependent on
	    the formula.
