worked, although I don't understand where the info went before, and the log
rotation option doesn't rotate anything but just truncates the log file on

Attaches to a local Java process and prints all minor and major GC's. Usually

what I'm doing wrong there?

Hi,
I have an application that often becomes laggy and shows slow responses almost
every day around 5 pm. The instance has daily scheduled restarts at 5 am, so it
occurs after 12 hours of use. When I restart it preemptively at 3 pm, the
