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 QOS data for a storage volume from among the plurality of storage volumes and the QOS data includes a response time in which the storage volume responds to an input/output (I/O) request; determines that the collected QOS data is noisy by comparing an average number of I/O requests processed within a time duration for the storage volume with a first threshold value; uses comparable QOS data of another storage volume for generating an expected range for future QOS data; and monitors QOS data for the storage volume for determining whether a current QOS data for the storage volume is within the expected range.

Abstract translation: 提供了用于从存储系统的存储操作系统监测多个存储卷的服务质量（QOS）数据的方法和系统。 性能管理器从多个存储卷中收集存储卷的QOS数据，并且QOS数据包括存储卷响应于输入/输出（I / O）请求的响应时间; 通过将在存储卷的持续时间内处理的平均I / O请求数与第一阈值进行比较来确定所收集的QOS数据是嘈杂的; 使用另一个存储卷的可比较的QOS数据来产生未来QOS数据的预期范围; 并监视存储卷的QOS数据，以确定存储卷的当前QOS数据是否在预期范围内。
