Method, system, and program for monitoring system components

A method for implementing a state machine to monitor a system component, comprising:

• providing a state class and status object class;
• instantiating a status object from the status object class, wherein the status object includes a current state variable indicating a current state of the state machine;
• instantiating multiple states of the state machine from the state machine class, wherein each state is capable of having a state action and notification performed when transitioning to the state from another state;
• generating at least one evaluation function for each state, wherein each evaluation function determines whether an operation on a measured system component satisfies a condition;
• and
• associating a transition state with each evaluation function;
• updating the status object to indicate the transition state as the current state if the associated evaluation function determines that the condition is satisfied.

A system for deriving state information concerning a monitored system component, comprising:

• a computer readable memory including:
• (i) a status object including information on a current state of the monitored system component;
• (ii) information indicating a plurality of states associated with the monitored system component, wherein each state is capable of having a state action and at least one transition condition associated with a transition state;
• means for receiving a measured system parameter;
• means for determining whether the received measured system parameter satisfies one transition condition associated with the current state indicated in the status object;
• and
• means for performing, if the received system parameter satisfies one transition condition, the action associated with the transition state associated with the satisfied transition condition;
• and
• means for setting the current state to the transition state in the status object.
