Retrieving muskie logs

These instructions are adapted from the comprehensive Manta Debugging Guide, with added clarification. See the debugging guide for more information on everything related to log-based debugging.

Log locations

Each zone maintains a log file for the current hour (a real-time log) at /var/log/muskie.log. At the top of every hour, the past hour's log file (now a historical log) is uploaded to the datacenter's manta at /poseidon/stor/logs/COMPONENT/YYYY/MM/DD/HH/SHORTZONE.log, where:

COMPONENT varies based on the component you’re looking for
YYYY, MM, DD, and HH represent the year, month, day, and hour for the entries in the log file
SHORTZONE is the first 8 characters of the zone’s uuid.
