State Variable Update Operation Window

Allows you to add and edit a state variable update operation. For more information about accessing the State variables from a script, see State Object. The fields are defined as follows:

Operation
Specifies the type of operation to perform.
Number of occurrences
Specifies the number of state variables to store. This field is only available with the Store the last N occurrences operation.
State variable name
Specifies the state variable name to update. This field is not available with the Store the last N occurrences operation.
State variable root
Specifies the root variable name by which to store the occurrences of variables. This field is only available with the Store the last N occurrences operation. When storing the last N occurrences of a variable, Microsoft Operations Manager 2000 (MOM) creates several variables stored with the state variable root. You can access these variable from a script through the State object. MOM creates the following variables with the state variable root:
State_Variable_Root.size
Specifies the number of occurrences stored. This value is equal to the value specified in the Number of occurrences field.
State_Variable_Root.first
Specifies which State_Variable_Root.N variable contains the earliest occurrence of the variable. If State_Variable_Root.first equals 4, then the earliest occurrence of the variable is stored in State_Variable_Root.4.
State_Variable_Root.last
Specifies which State_Variable_Root.N variable contains the latest occurrence of the variable. If State_Variable_Root.last equals 2, then the latest occurrence of the variable is stored in State_Variable_Root.2.
State_Variable_Root.N
Specifies each of the occurrences of the variable. N can be 1 to the value specified in the Number of occurrences field. The occurrences cycle through the N variables overwriting the oldest occurrence. Use the .first and .last variables to keep track of the order of occurrences.
Property
Specifies the event or alert property to which to set the state variable. This field is only available with the Set variable value to property or Store the last N occurrences operation.
Text
Specifies the text to which to set the state variable. This field is only available with the Set variable value to text operation. You can specify the $State Variable$ variable in the Text field. The $State Variable$ variable represents the value of the variable before the state variable update operation is performed.
Number
Specifies the number to which to set the state variable. This field is only available with the Set variable value to number operation.
