Customized updates are generated for instances of storage management software running on storage management servers in different storage systems. The filenames of class files used by each instance of the storage management software are stored in respective databases associated with those storage management software instances. Thread dumps are created and searched for class files of the storage management software to create a baseline. The baseline is updated by comparing class files used in response to UI actions and REST API calls and storing names of class files that are not already in the database. To update an instance of the storage management software, the class files of a general update are compared with the filenames in the database associated with the instance and non-matching files are omitted from the customized update foe that instance.

Targeted updates of storage management software based on class file usage

Storage array health scores based on alerts are auto-corrected by using alert validation and alert matching to identify missed, stale, and redundant alerts. In response to restoration of an event daemon or reboot of a storage management server, each alert associated with each storage array is validated to determine whether current state of storage array hardware or a logical object differs from the state indicated in the alert. Alerts that differ from current state are updated or invalidated and the health score is recalculated. Responsive to receipt of a new alert, existing alerts associated with the same storage array hardware or logical object are identified and Jaro-Winkler distance between the identified alerts and the new alert is calculated. Any existing alert for which the Jaro-Winkler distance relative to the new alert is greater than or equal to 0.9 is deleted and the health score is recalculated.
