Monitoring a resource consumption of an application

A computer program product, comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a data processing system to implement a method for monitoring a resource consumption of an application running on a computer, said method comprising:

• performing, by the one or more processors, a wavelet analysis of a first function of time, wherein a first metric describes the resource consumption of the application as a first function of time;
• detecting, by the one or more processors, a discontinuity in the first function at a first time at which a coefficient determined from the wavelet analysis exceeds a specified threshold, said coefficient being indexed on a dilation parameter and a time offset parameter;
• calculating, by the one or more processors, a cross-correlation of the first metric and a second metric describing the resource consumption of the application as a second function of time;
• adjusting, by one or more processors, a diagnostic level associated with the discontinuity in the first function, said adjusting based on the calculated cross-correlation;
• and
• in response to adjusting the diagnostic level, starting, by the one or more processors, a debugging function on the application in response to the cross correlation having a value indicative of an anomaly within the application.
