newbie question here…
looks like my system isn’t using swap…
root@testvm:~# free -m total used free shared buff/cache available Mem: 985 667 72 3 245 176 Swap: 0 0 0
a few questions
- do i have to enable swap? I realize it’s not a good thing and you want to avoid it, but i dont know if it’s something you have to turn on or if the OS creates it as needed? the fact that my server just shows "0" for everything kind of confuses me.
- is there a way to see if swap was ever used? i believe the "free -m" command shows current usage. but say for instance somethnig happens overnight that causes swap usage but the situation goes away and the swap is cleared out. is there a way that i could see it was used? (time/amount/etc would be great but i’ll settle for anything at this point).
