Example usage:
python analyze_reboot_time.py -l 12 --server cautotest --board daisy_spring
Usage: analyze_reboot_time.py [-h] [-l LAST] --server AUTOTEST_SERVER
[--board BOARD] [--pool POOL] [--start START]
[--end END] [--gte GTE] [--lte LTE] [-n SIZE]
[--hosts HOSTS [HOSTS ...]]
optional arguments:
-h, --help show this help message and exit
-l LAST last hours to search results across
--server AUTOTEST_SERVER
Enter Autotest instance name, e.g. "cautotest".
--board BOARD restrict query by board, not implemented yet
--pool POOL restrict query by pool, not implemented yet
--start START Enter start time as: yyyy-mm-dd hh-mm-ss,defualts to
24h ago.
--end END Enter end time as: yyyy-mm-dd hh-mm-ss,defualts to
current time.
--gte GTE Enter lower bound on reboot time for entries to
return.
--lte LTE Enter upper bound on reboot time for entries to
return.
-n SIZE Maximum number of entries to return.
--hosts HOSTS [HOSTS ...]
Enter space deliminated hostnames
