A system comprising a memory heap generated dynamically by useful software and a data acquisition engine. The memory heap comprises a plurality of event structures, each including at least one each of pointers into memory external to the event structure, event operators, and arguments. The data acquisition engine is configured to look into the memory heap, evaluate event conditions as true or false based on the at least one each of the pointers, operators, and arguments, and generate a notification message when a true condition is found.
