/**
 * Describe the type of data that is to be collected. The typical type is "measurement" (i.e. numeric) data that
 * normally changes over time (see {@link NumericType} for further classification of this kind of data). A "trait" is
 * typically a value that changes rarely (e.g. number of CPUs on a platform, or an install path). "Complex" data is
 * tabular in nature with N columns of N rows of values. Call-time data is the min/max/avg call durations for each
 * destination (e.g. URL or session EJB method) in a set of destinations.
