Reservation of hardware resources in a computer system based on utilization measurements during time ranges

A resource management computer node comprising:

• a network interface circuit configured to communicate with hardware resources of a computer system;
• a processor circuit coupled to the network interface circuit;
• and
• a memory circuit coupled to the processor circuit and storing program code which when executed by the processor circuit causes the processor circuit to perform operations comprising:
• obtain hardware utilization values measured for at least one of the hardware resources being used by a software application;
• for a set of the hardware utilization values that were measured during a same time-of-day range on a same day of week,
• determining a count value indicating a number of times the hardware utilization values in the set exceed a count threshold value,
• determining a count percentage value based on a ratio of the count value to a sum of count values determined for the same day of week,
• comparing the count percentage value to a busy threshold value,
• responsive to if the count percentage value is determined to exceed the busy threshold value,
• setting a busy indicator object at a location in a resource utilization data structure having a defined correspondence to the time-of-day range;
• and
• controlling reservation of the hardware resources for operational use by the software application during at least the time-of-day range responsive to whether the busy indicator object has been set at the location in the resource utilization data structure;
• and
• subsequent to the controlling reservation of hardware resources, running the software application on the reserved hardware resources during at least the time-of-day range.
