1. A method for execution by a managing unit that includes a processor, the method comprises:
receiving log information from a plurality of entities of a distributed storage network (DSN) for storage in a vault of the DSN;
detecting an error condition with regards to at least one of the plurality of entities;
generating error correlation information that includes an identified at least one of the plurality of entities based on the error condition and the log information, wherein generating the error correlation information is based on:
retrieving the log information from the vault; and
identifying a pattern of the log information with a correlation factor greater than a correlation threshold level; and
issuing a message to the plurality of entities of the DSN that indicates a DSN configuration change based on the error correlation information.
