comment IIS applications appear in appcmd but not in IIS manager tree view
I may have partially answered my own question. The app BaseMetals has a physical path of D:\fm_websites\BM\MyDesk. The three apps above have virtual paths Basemetals/_testing_/... but there is no VDIR or app that maps to Basemetals/_testing_ itself, and no D:\fm_websites\BM\MyDesk_testing_ directory exists in the filesystem. If I create a directory there, the apps appear when I refresh the tree. This does still leave open the question of how to scan the configuration for this problem!

comment Move IP from one server to another without disruption
I actually do have two DNS servers placed on two subnets, but from what I've read the idea of primary and secondary DNS is bogus and multiple DNS servers were originally for load balancing, not failover. That means clients are free to hit any DNS in the list first, not just the first one. Also I see in practice it takes clients 5 seconds or more to time-out their DNS request and try another server, which creates serious problems.

I think you've nailed it! I confess I never paid much attention to how VMWare memory allocation worked, but having just read up on it I think you are exactly right. I use open-vm-tools, so the process was /usr/bin/vmtoolsd and the module is vmw_balloon. Looking at it now, vCenter shows a balloon of 2452880kb for that machine, which is certainly about the right size to explain the discrepancy. root@betacms1:/var/log/nginx# vmware-toolbox-cmd stat balloon 1945 MB

Thanks for the reply. I like htop, and I'm using it on the servers - it was through it that I first noticed the discrepancy. But htop alone doesn't show the problem, since it's not a program that is using the memory (as far as I can tell).

Based on that equation, I get these figures:- sum(RSS) = 30612 Memfree = 506576 Slab = 94516 Pagetables = 1012 VmallocUsed = 281340 Buffers = 242252 Cached = 486796 From that, I'd expect a usage without cache and buffers of 914056k and a total usage of 1643104kb.

I came across the formula MemTotal = MemFree + Slab + PageTables + VmallocUsed + Buffers + Cached + sum(RSS) ( on blog.thewebsitepeople.org/2011/03/linux-memory-leak-detection ). In this case, the numbers just don't add up.
