> We specify the logging pattern as "%-5level [%thread] %date{ISO8601} %F:%L - %msg%n".

> %F:%L is intended to print the Filename:Line Number. For performance reasons logback
(like log4j2) disables tracking line numbers as it requires the entire stack to be materialized
every time.
> This causes logs to look like:
> WARN  [main] 2017-03-09 13:27:11,272 ?:? - Protocol Version 5/v5-beta not supported by
java driver
> INFO  [main] 2017-03-09 13:27:11,813 ?:? - No commitlog files found; skipping replay
> INFO  [main] 2017-03-09 13:27:12,477 ?:? - Initialized prepared statement caches with
14 MB
> INFO  [main] 2017-03-09 13:27:12,727 ?:? - Initializing system.IndexInfo
> When instead you'd expect something like:
> INFO  [main] 2017-03-09 13:23:44,204 ColumnFamilyStore.java:419 - Initializing system.available_ranges
> INFO  [main] 2017-03-09 13:23:44,210 ColumnFamilyStore.java:419 - Initializing system.transferred_ranges
> INFO  [main] 2017-03-09 13:23:44,215 ColumnFamilyStore.java:419 - Initializing system.views_builds_in_progress
> The fix is to add "<includeCallerData>true</includeCallerData>" to the appender
config to enable the line number and stack tracing.
