Updating of troubleshooting assistants

摘要

Methods and arrangements for providing assistance with troubleshooting for system updates. There is sent, to a first database, a feature log associated with an update event at a first location. The feature log is pooled in the first database with feature logs associated with update events at other locations. A signature is created of at least one update from the first database, and the signature is added to a signature database. The signature database is employed to identify one or more deviations, when the at least one update fails in at least one location. The one or more deviations are ranked with respect to at least one other deviation. Other variants and embodiments are broadly contemplated herein.

主权项

1. A method of providing assistance with troubleshooting for system updates, the method comprising:
utilizing at least one processor to execute computer code configured to perform the steps of: creating a feature log associated with introduction of a system update at a first location; pooling the feature log with feature logs associated with introduction of the system update at other locations; based on said pooling, creating a signature of the system update wherein the signature conveys values of features contributing to different execution sequences for the system update, and wherein the creating comprises identifying features across trace logs from different locations where an update follows the same execution sequence before accessing a feature; and identifying one or more deviations from the signature when the system update fails in at least one location.
