I've been noticing that my server has been using swap a quite more often now but I can't seem to figure out why. The munin graph shows that the apps memory usage is about 0.7G out of the 1.5G. The concern I have is the green line (committed memory). What is committed memory? Is it normal that the committed memory is high compared to the other memory stats, such as apps?
I want to know if I can optimize my apps a bit more or do I really need to just get more RAM for the server.
Currently running daemon apps on this one little server:
- Node JS
