Predictive monitoring with wavelet analysis

A computer program product for monitoring a plurality of hardware or software system resources for identifying hidden trends in the behavior of the system resources, the computer program product comprising:

• a computer readable memory device having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code configured to:
• collect metrics of at least one system resource indicative of the behavior of at least one system resource;
• for each of the at least one system resource, determine a spectrum representative of a time-based signal of the collected metrics;
• perform a wavelet transform on each of the at least one spectrum;
• analyze the result of the wavelet transform to identify possible linear trends in the behavior of the at least one system resource;
• assign to each identified linear trend a severity value indicative of a criticality of the related behavior wherein the criticality of behaviors comprises an indication of how fast a predetermined threshold of the related system resource will be reached;
• and
• rank the severity value with respect to at least one other severity value to identify an order in which to address the behavior of the at least one system resource.

A system, comprising:

• a plurality of system resources, comprising hardware or software system resources;
• and
• a computer for monitoring the plurality of system resources, wherein the computer:
• collects metrics of at least one system resource indicative of the behavior of at least one system resource;
• for each of the at least one system resource, determines a spectrum representative of a time-based signal of the collected metrics;
• performs a wavelet transform on each of the at least one spectrum;
