Available Memory
- Organization of this page
Overview
The Available Memory alarm monitors the size of the physical memory actually available to applications (in megabytes).
- In Windows:
-
The monitored value is the total size of zero memory, available memory, and standby memory (already cached) that can be allocated to processes or that can be used immediately by the system during collection.
- In Linux, AIX, or Solaris:
-
The monitored value is the free space of memory plus the amount of releasable areas assigned to the caches and buffers.
- In HP-UX:
-
The monitored value does not include the amount of releasable areas assigned to the caches and buffers.
This is the most recent monitored value, not an average value.

If the monitored host is a non-global zone environment of Solaris, do not use this alarm. If you want to monitor the free memory in a non-global zone environment, use an alarm that monitors the Free Mem Mbytes field.
