Coverage model and measurements for partial instrumentation

A computerized apparatus having a processor coupled with a memory unit, the processor being adapted to perform the steps of:

• determining an instrumentation coverage model of a system having components, the instrumentation coverage model defining instrumentation tasks of the system, wherein each instrumentation task defines a subset of the components to be monitored;
• and
• monitoring the system, wherein during said monitoring applying a plurality of partial instrumentation tasks defining strict subsets of the components to be monitored.

A computer program product comprising a non-transitory computer readable medium retaining program instructions, which instructions when read by a processor, cause the processor to perform the steps of:

• determining an instrumentation coverage model of a system having components, the instrumentation coverage model defining instrumentation tasks of the system, wherein each instrumentation task defines a subset of the components to be monitored;
• and
• monitoring the system, wherein during said monitoring applying a plurality of partial instrumentation tasks defining strict subsets of the components to be monitored.
