Metric subset selection for dynamic performance monitoring

A computer program product comprising:

• one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media to perform operations comprising:
• receiving observability metrics associated with a system;
• quantifying the observability metrics by determining an entropy value associated with the respective observability metrics;
• for a subset of the observability metrics having respective entropy values that are in a first predetermined range, comparing mutual information measures between pairs of the observability metrics in the subset;
• and
• in response to determining differences between the mutual information measures of a given one of the pairs of the observability metrics are outside a second predetermined range:
• selecting one of the observability metrics in the given pair to maintain, and
• discarding the remaining one of the observability metrics in the given pair.

A computer system comprising:

• a processor set;
• one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media to cause the processor set to perform operations comprising:
• receiving observability metrics associated with a system;
• quantifying the observability metrics by determining an entropy value associated with the respective observability metrics;
• for a subset of the observability metrics having respective entropy values that are in a first predetermined range, comparing mutual information measures between pairs of the observability metrics in the subset;
• and
• in response to determining differences between the mutual information measures of a given one of the pairs of the observability metrics are outside a second predetermined range:
• selecting one of the observability metrics in the given pair to maintain, and
• discarding the remaining one of the observability metrics in the given pair.
