Hello,
Recently I've noticed that the system information page in Virtualmin is displaying:
188 MB total, 149.97 MB used
whereas free -m shows the following:
total used free shared buffers cached
Mem: 752 340 411 0 0 0
-/+ buffers/cache: 340 411
Swap: 8192 0 8192
Anyone got any ideas?
Many thanks, Martin
That's rather odd... Both that Virtualmin is so off for "total memory", and your "free" output looks strange too. "cached" should never be higher than "used", because "used" includes "cached". What distribution are you using there? For me (Ubuntu 12.04 x64), the "free" output looks like so:
Generally, Virtualmin's "used" display is "used minus cached" in free, because memory used as file system cache is "semi-free", i.e. it can be assigned to applications at any time.
EDIT: Sorry, I got confused by your linebreak-less output! :D I overlooked that your shared, buffers and cached is all at 0.
So yeah, Virtualmin indeed seems to be detecting the memory completely wrong there. WHat happens when you click the "Refresh information" link on top of the page? I'm not sure which command Webmin uses to determine memory stats, I suppose Eric or Jamie could fill us in there.
Thanks Locotus. Sorry about the confusion with the output of free!
I'm running Centos 5.9.
The output on the system information page is still wrong when I refresh...
It's not a big problem - just something I noticed and wondered if anyone else had the same problem...
Thanks, Martin
Howdy,
Hmm, are you using a VPS of some sort? If so, what kind of VPS is it?
Also, can you paste in the contents of /proc/meminfo?
Thanks!
