A non-transitory, computer readable storage device includes software that, while being executed by a processor, causes the processor to choose, based on user activity, a plurality of candidate parameters to be monitored from a plurality of event messages. Further, the processor executes the software to estimate a level of similarity between the chosen plurality of candidate parameters by computing a similarity score for at least two of the chosen candidate parameters. Still further, the processor executes the software to determine a plurality of parameters from the chosen candidate parameters if the similarity score for the plurality of parameters is greater than a threshold.
