Hi Suraj,

I just need to check/monitor the physical memory. Not any others.

It is not simple.

You need to take the buffer cache settings and usage into account.

I would argue that the better way of testing 2GB free is to test whether the UBC if free memory + the difference of current UBC usage ( kmeminfo) and the UBC max is less than 2GB.

You see, the UBC is allowed to eat into free memory, but ready to give it back when needed for process memory.

Amreek,

You can run the kmeminfo utility in loop and grep the physical memory usage.

For kmeminfo : check out: http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1125085


- Put one 'if-then' condition with meminfo output: if free memory less than 2GB , then execute mailx to send alert.


Hth,
Raj.
