Does enabling SPSS_LOG_LEVEL=DEBUG consolidate fatal SPSS deployment errors into a single log message?

The goal is to determine whether enabling verbose logging via the SPSS_LOG_LEVEL=DEBUG environment variable changes the way fatal deployment errors are recorded in SPSS installation logs. Default logs contain timestamps, component names and error codes but lack a consolidated summary, forcing administrators to collect scattered warnings to diagnose a failure.

Constraints include the unknown impact of DEBUG level on log size and performance, which IBM documentation notes is not standardized across SPSS versions, and the fact that log file locations differ between SPSS Statistics client and SPSS Server deployments, so a single path cannot be assumed. Does SPSS_LOG_LEVEL=DEBUG produce a single, actionable error message for failed deployments? Is the additional diagnostic detail worth the potential log size increase across versions?
