Profile clustering for homogenous instance analysis

A system comprising:

• a memory having computer readable instructions;
• and
• one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
• collecting for each of a plurality of homogenous instances in a cloud computing environment, respective profiling information, the profiling information comprising counter data;
• generating a map based on the collected profiling information, wherein the map comprises associations between process identifiers, code modules, and effective address ranges;
• identifying a code unit for analysis;
• aggregating counters corresponding to the code unit for each of the plurality of homogenous instances from the respective profiling information, wherein aggregating the counter data corresponding to the code unit comprises looking up an effective address of sampled code in the code unit, and process identifier of the code unit, in the map;
• and
• determining a cluster comprising a subset of the plurality of homogenous instances based on the aggregated counters.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:

• collecting for each of a plurality of homogenous instances in a cloud computing environment, respective profiling information, the profiling information comprising counter data;
• generating a map based on the collected profiling information, wherein the map comprises associations between process identifiers, code modules, and effective address ranges;
• identifying a code unit for analysis;
• aggregating counters corresponding to the code unit for each of the plurality of homogenous instances from the respective profiling information, wherein aggregating the counter data corresponding to the code unit comprises looking an effective address of sampled code in the code unit, and process identifier of the code unit, in the map;
• and
• determining a cluster comprising a subset of the plurality of homogenous instances based on the aggregated counters.
