What's the best way to monitor Terracotta's memory usage and GC performance?

Is the Dev Console the best way to do that?

Or should I be using a JMX console or should I simply monitor the log files (turn on GC verbose and print options)

Hi ,

Dev console is good for this , you can use the monitor section in dev-console to view these details.

I would recommend using verbose GC or jstat. The Dev console will show you the heap, but not how GC is performing.

How do you in general decide on the maximum memory configuration for the terracotta servers?

Is it just an estimate of the maximum amount of data that'll be cached?

I assume if cached data can't fit in memory, it'll save to the file system.
