• extra: extra information, depending on the source of the event

2.  Private memory threshold exceeded

Event: E_CORE_PKG_THRESHOLD

• threshold: the event_pkg_threshold specified in the script.
• used: the amount of private memory used.
• size: the total amount of private memory.
• pid: the pid of the process that raises the event.

3.  Shared memory threshold exceeded

Event: E_CORE_SHM_THRESHOLD

This event is triggered when the shared memory usage goes above a threshold limit, specified by the event_shm_threshold the core parameter. It warns external applications about low values of free shared memory.

Parameters:

• usage: the percentage of private memory usage. Can have values between event_shm_threshold and 100.
