1. A method for performing an availability measurement on a networked system comprising:
identifying at least one measurement point in the system;
defining a measurement model configured to return a pass or fail result corresponding to a threshold sensed at said at least one measurement point and to a measurement function;
measuring said system using said measurement model, wherein said measuring said system comprises a plurality of measurements;
collecting a plurality of pass or fail results from said plurality of measurements, wherein each one of said plurality of pass or fail results corresponds to a measurement point and to a measurement function of one or more measurements; and
aggregating said plurality of pass or fail results to formulate a single availability value representing the availability of said system.
