Monitor Global Manager memory usage

Monitor memory usage by the Global Manager to ensure that it does not exceed the operating system’s memory limit and as a way to detect possible performance issues.

Although monitoring memory usage should be part of a routine, these symptoms require immediate investigation:

• Fast memory growth after the Global Manager has reached a steady state, such as hundreds of megabytes of memory growth in a few hours. The steady state is typically reached sometime after startup: Be conservative and allow a few hours after startup before assuming that the Global Manager is in the steady state.

• Consistent memory growth over time, never reaching a plateau. This is relevant only if the overall growth of the Global Manager process is also hundreds of megabytes of memory, after reaching steady state.
