Hi,

In my cassandra logs, I see a lot of "StatusLogger" output lines. I'm
trying to understand why this is logged, and how to interpret the output.
Maybe someone can point me to some documentation on this particular logging
aspect?

I would like to know what is triggering the StatusLogger.java to start
logging? Sometimes it logs every few seconds, and sometimes it won't log
for hours.

Also, about the lines that log "Memtable ops, data" per ColumnFamily, what
do these figures mean? Is it number of operations and data size (bytes, MB,
...)? Are the ops counters reset every time they are logged, or e.g. every
x minutes?


Any help is greatly appreciated!
Thanks,
Tom
