Source note · CUCM CallManager SDL trace files
From Unified Communications Manager 8.0 onward the log compression feature compresses certain log files in gzip format, the file currently being written carries a .gzo extension, and CLI view and tail commands uncompress automatically.
Checked 2026-09-22
The compressed files have a .gz extension. The file that is being actively written to the disk will have a .gzo extension. All the CLI commands used to view and tail the files will work on the compressed files and will automatically uncompress them for viewing or tailing.
