I'm wondering if our system has lots of free RAM, or if its almost out. I read here regarding MemAvailable but I am wondering how it applies to VirtualBox as I am sure thats the reason the numbers I get from the following commands differ so much.
cat /proc/meminfo | grep Mem && free -lg MemTotal: 32771584 kB MemFree: 203372 kB MemAvailable: 27739104 kB total used free shared buffers cached Mem: 31 31 0 0 0 25 Low: 31 31 0 High: 0 0 0 -/+ buffers/cache: 5 25 Swap: 31 0 31
We have only allocated about 15GB of RAM to our VM's and the sytem has 32GB's. Does the above output seem normal, do we have 27 GB of free RAM to allocate? Or are we almost out? Or perhaps a memory leak? Any ideas are welcome! Thank you in advnace
