This script convert_dmesg_time.sh may help us correlate system events occurred in dmesg with other ES events by converting system time to human readable local time in dmesg.

Disclaimer, the human readable output in dmesg may be off by few seconds.

Usage:

cd diagnostics-%datetime%
convert_dmesg_time.sh

Prerequisite: It reads files collected from ES support diagnostics tool. The following files must be present for it to work.

• dmesg.txt (with system timestamp)
• top.txt
• manifest.json

Example input: (dmesg.txt)
