comment Do I have an under-voltage issue in my data room I need to address?
About your last paragraph: If you have two 750W/110V servers on a 15A breaker, and add a third, that's ~20A. That doesn't cause a brown-out (well, maybe for a fraction of a second), instead that causes your breaker to trip. Or, if not, potentially causes a fire.

@TessellatingHeckler Hah, yep. Coming from a Unix background, I definitely understand that!

See also Getting the currently logged-in user to a Windows XP Pro system for a related (much newer) question which can also be used to do this.

comment How to find files affected by reallocated sectors?
@Nick If you want to ensure data integrity, you need to keep checksums of your files. Then you can use the checksums to answer "has anything been corrupted?" (And replace with another copy, which you can confirm is correct using the checksum)

comment With virtualization, does it still make sense to use multiple mount points?
Why do you have to reboot to increase the size of a mount point? I think all the common filesystems support online expand at this point.

comment Getting the currently logged-in user to a Windows XP Pro system
Trying the queries in your PowerShell script quickly by hand as administrator shows they work. Thank you! I'll figure out the permissions needed Monday.

comment Getting the currently logged-in user to a Windows XP Pro system
Actually, with more testing, it only works if the querying account is the same as the logged in account. Otherwise, it always returns null. This is weird—and maybe a config error somewhere—but good enough to get this monitored...

comment Getting the currently logged-in user to a Windows XP Pro system
That query seems to give me the user that is logging in to do the WMI query, not the desktop user... select username from Win32_ComputerSystem seems to work, but only if run as an administrator (must be a permission I have to set somewhere)... it's giving null as non-admin.

comment Getting the currently logged-in user to a Windows XP Pro system
Hmmm... none of these seem easily doable from the non-Windows monitoring server. Though looking for WMI stuff, after looking at your second link, looks like there is a WMI client for Linux... Will see if that works. No idea if WMI is even supported on XP.

comment Is it possible that just one bit switches so my file shows me a letter “Q” instead of a “S”
@psusi Not impossible, as you just need enough bit-flips in the sector to make the ECC come out right. Unlikely, but possible, and disk manufacturers quote high enough error rates that you really ought to expect to see some. I've heard rumors that ZFS folks see them (due to ZFS-level data checksums)...
