How available memory is showing up on Centos?
by james000 from LinuxQuestions.org on (#6FAYR)
I am looking at my Centos VM and trying to understand memory. I know that cache + free memory is supposed to be available (for apps) memory. But here it is 431M + 2.1GB is free+cache. How 26gb is available ?
Code:[root@Centos-4444 ~]# free -h
total used free shared buff/cache available
Mem: 31G 28G 431M 97M 2.1G 26G
Swap: 15G 19M 15G
[root@Centos-4444 ~]#Problem is, monitoring tool is looking at free memory and creating ticket for us that free memory is only 431MB.
Please suggest. Thanks
