sg_collect does not package archived log files (*.log.gz)

I have run Sync Gateway system test for 3 days. when test completes, Sync Gateway is stopped by test framework.

I went to /opt/couchbase-sync-gateway/tools/ run sg_collect by pointing an output location, and leave everything else default

The sg_collect output package (attached) only contains the most current log files in the sync gateway home directory, archived logs *.log.gz are not included in the package.

system test installs Sync Gateway on CentOS 7 VM. Sync Gateway version used is 2.8.2-1
