Monitoring index screening method and system for IT resources and medium

The invention discloses an IT resource monitoring index screening method and system and a medium, and the method comprises the steps: determining a tag associated with a target IT resource, and recording the tag as a first tag; determining all directly belonging ancestor tags of the first tag based on a preset tag tree; and matching the first tag and the directly subordinate ancestor tag with a monitoring index, and screening out a target monitoring index which is used for collecting performance data corresponding to a target IT resource. According to the method and the device, through the indexes and the IT resources marked by the labels, the appropriate monitoring indexes can be automatically screened out through the labels to collect the performance data of the target IT resources; and the labels are stored through the tree structure, so that the label types can be flexibly expanded when new IT resource types appear, and the expansibility of index screening is improved. 本申请公开了一种IT资源的监控指标筛选方法、系统及介质，其中方法包括：确
