Collecting tracepoint data includes: maintaining, by a log handler, a list of a plurality of tracepoints and each tracepoint's parameters, the values of the parameters defining, for a tracepoint, information to be stored when an application encounters the tracepoint; encountering, by an application, a tracepoint; determining, responsive to the encounter by the log handler, whether the tracepoint is linked to a different tracepoint; and if the tracepoint is linked to a different tracepoint, determining, by the log handler, whether to modify values of the parameters for the different tracepoint and executing the different tracepoint.
