Host device providing automated prediction of change intervals to reduce adverse impacts on applications

An apparatus comprising:

• a host device comprising a processor coupled to a memory;
• the host device being configured to communicate with a storage system;
• wherein the host device is further configured:
• to monitor host device operating parameters relating to its interaction with the storage system over a plurality of intervals;
• for each of the intervals, to aggregate threshold-based assessments of respective ones of the monitored host device operating parameters and to classify the interval based at least in part on the aggregated threshold-based assessments;
• and
• to identify a particular future interval for use as a change interval for changing one or more characteristics of an operating environment of the host device based at least in part on the classified intervals;
• wherein aggregating threshold-based assessments of respective ones of the monitored host device operating parameters for a given interval and classifying the interval based at least in part on the aggregated threshold-based assessments comprises:
• responsive to all of the threshold-based assessments of respective ones of the monitored host device operating parameters for the given interval indicating that the interval is designated as preferred, classifying the interval as preferred across the monitored host device operating parameters;
• and
• responsive to at least one of the threshold-based assessments of respective ones of the monitored host device operating parameters for the given interval indicating that the interval is designated as non-preferred, classifying the interval as non-preferred across the monitored host device operating parameters.

A method performed by a host device comprising a processor coupled to a memory, the host device being configured to communicate with a storage system, the method comprising:

• monitoring host device operating parameters relating to its interaction with the storage system over a plurality of intervals;
• for each of the intervals, aggregating threshold-based assessments of respective ones of the monitored host device operating parameters and classifying the intervals based at least in part on the aggregated threshold-based assessments;
• and
• identifying a particular future interval for use as a change interval for changing one or more characteristics of an operating environment of the host device based at least in part on the classified intervals;
• wherein aggregating threshold-based assessments of respective ones of the monitored host device operating parameters for a given interval and classifying the interval based at least in part on the aggregated threshold-based assessments comprises:
• computing a value for the given interval as a function of the aggregated threshold-based assessments;
• and
• updating at least one data structure to include the computed value in an entry corresponding to the given interval.

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code, when executed by a host device comprising a processor coupled to a memory, the host device being configured to communicate with the storage system, causes the host device:

• to monitor host device operating parameters relating to its interaction with the storage system over a plurality of intervals;
• for each of the intervals, to aggregate threshold-based assessments of respective ones of the monitored host device operating parameters and to classify the intervals based at least in part on the aggregated threshold-based assessments;
• and
• to identify a particular future interval for use as a change interval for changing one or more characteristics of an operating environment of the host device based at least in part on the classified intervals;
• wherein aggregating threshold-based assessments of respective ones of the monitored host device operating parameters for a given interval and classifying the interval based at least in part on the aggregated threshold-based assessments comprises:
• computing a value for the given interval as a function of the aggregated threshold-based assessments;
• and
• updating at least one data structure to include the computed value in an entry corresponding to the given interval.
