Tyler Hobbs commented on CASSANDRA-11352:
-----------------------------------------
Thanks for the patch!
I've started CI test runs here:
||branch||testall||dtest||
|[CASSANDRA-11352-trunk|https://github.com/thobbs/cassandra/tree/CASSANDRA-11352-trunk]|[testall|http://cassci.datastax.com/view/Dev/view/thobbs/job/thobbs-CASSANDRA-11352-trunk-testall]|[dtest|http://cassci.datastax.com/view/Dev/view/thobbs/job/thobbs-CASSANDRA-11352-trunk-dtest]|
I made a couple of minor changes to the output for improved readability:
* Lowered the amount of padding to handle the max numbers that we could
reasonably see
* Added spaces in between numbers and units. I know that we don't use a space
in log messages, but considering how dense the information is in stress output,
I think it's better to maximize readability.
bq. Total GC time is in seconds while other GC measures are in milliseconds.
This could be misleading, I'm waiting reviewer comment on this
I think this is fine. I changed the unit to be "seconds" instead of just "s"
to make sure this is clear.
