Providing utilization and cost insight of host servers

A data analyzer, comprising:

• a processor;
• and
• a memory having instructions stored thereon which, when executed by the processor, cause the processor to:
• collect, via respective agents running on respective host servers in a cloud computing environment, respective energy consumption data representing energy consumed by the respective host servers over a time period, wherein the agents communicate with hardware on each of the respective host servers using a unified application programming interface (API);
• determine respective energy costs over the time period for the respective host servers based on the respective energy consumption data;
• identify a subset of the respective host servers that are being underutilized based on the respective energy consumption data and the respective energy costs;
• determine an action to take with respect to the subset of the respective host servers that are being underutilized to reduce the energy costs;
• and
• initiate the action or present an alert identifying the subset of the respective host servers that are being underutilized.

A non-transitory computer readable medium comprising computer executable instructions stored thereon that, when executed by a processor, cause the processor to:

• collect, via respective agents running on respective host servers in a cloud computing environment, respective energy consumption data representing energy consumed by the respective host servers over repeating time periods, wherein the agents communicate with hardware on each of the respective host servers using a unified application programming interface (API);
• and
• for each time period:
• determine respective energy costs for the respective host servers based on the respective energy consumption data;
• identify a subset of the respective host servers that are being underutilized based on the respective energy consumption data and the respective energy costs;
• determine an action to take with respect to the subset of the respective host servers that are being underutilized to reduce the energy costs;
• and
• initiate the action or present an alert identifying the subset of the respective host servers that are being underutilized.
