1. A machine implemented method, comprising:
- collecting quality of service (QOS) data for a plurality of storage volumes from a storage operating system of a storage system;
wherein a processor executable performance manager collects the QOS data from the storage operating system and the QOS data includes a response time in which each of the plurality of storage volumes respond to an input/output (I/O) request;
generating an expected range for future QOS data based on the collected QOS data; and
monitoring QOS data for each storage volume for determining whether a current QOS data for each storage volume is within the expected range.

Abstract
Methods and systems for monitoring quality of service (QOS) data for a plurality of storage volumes from a storage operating system of a storage system are provided. A performance manager collects the QOS data from the storage operating system and the QOS data includes a response time in which each of the plurality of storage volumes respond to an input/output (I/O) request. An expected range for future QOS data is generated based on the collected QOS data. The QOS data is monitored for each storage volume for determining whether a current QOS data for each storage volume is within the expected range.

10. A non-transitory, machine readable storage medium storing executable instructions, which when executed by a machine, causes the machine to perform a method, the method comprising:
collecting quality of service (QOS) data for a plurality of storage volumes from a storage operating system of a storage system;
wherein a performance manager collects the QOS data from the storage operating system and the QOS data includes a response time in which each of the plurality of storage volumes respond to an input/output (I/O) request;generating an expected range for future QOS data based on the collected QOS data; and monitoring QOS data for each storage volume for determining whether a current QOS data for each storage volume is within the expected range. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system, comprising:
-
a processor of a storage system executing a storage operating system for managing access to a plurality of storage volumes for storing information at a plurality of storage devices; and a processor for a performance manager executing instructions out of a memory device for collecting quality of service (QOS) data for the plurality of storage volumes from the storage operating system;
generating an expected range for future QOS data based on the collected QOS data; and
monitoring QOS data for each storage volume for determining whether a current QOS data for each storage volume is within the expected range;wherein QOS data includes a response time in which each of the plurality of storage volumes respond to an input/output (I/O) request; and wherein the expected range provides a dynamic threshold value to the performance manager for predicting an incident associated with any of the plurality of storage volumes and determining if any of the resources is in contention between any of the plurality of storage volumes resulting in a storage volume becoming a victim due to overuse by another storage volume. - View Dependent Claims (20)
