Want to know whether enough memory is free on a linux machine to deploy a new application.

Question

I have got a linux machine whose memory snapshot when I do /proc/meminfo is :

MemTotal:     16413388 kB
**MemFree:         48296 kB**

HugePages_Free:      0
Hugepagesize:     2048 kB

This is a 16 GB machine and I have a Java application to deploy on this which will have 3 jvm instances and combined typical memory requirement for them will be close to 1 GB.

I wanted to know will it be safe to deploy that application without affecting other applications currently running on that machine. By looking at the above memory snapshot can we find out?

What other statistics will help me to decide that and how to collect those statistics?
