System statistics provide information about overall performance and status of the Online system. Some identically named statistics might also be available on the user, file, subsystem, or task level. Generally, an identically named statistic for a different context will have a similar meaning to the system context.

In RKWeb, you can display all the system statistics and view their descriptions by selecting Performance > Custom from the Monitor tab, then clicking the System radio button.
