PROGRAM: mttf.c
|
|
|
|
AUTHOR: Lars Opstad (LarsOp) 3/16/93
|
|
|
|
PURPOSE: NT Mean-time-to-failure reporting tool.
|
|
|
|
FUNCTIONS:
|
|
|
|
WinMain() - check for local file, read ini file and display dialogs
|
|
SignonDlgProc() - processes messages for signon dialog
|
|
EventDlgProc() - processes messages for event (other problem) dialog
|
|
|
|
COMMENTS:
|
|
|
|
This program displays 2 dialog boxes to prompt the user for
|
|
what type of problem occurred.
|
|
|
|
Every polling period, the time in the mttf data file is updated
|
|
(as either busy or idle based on percent of cpu usage). If a machine
|
|
is idle for more than 4 hrs, the "gone" field is increased by the time
|
|
gone. Whenever the program starts, the user is prompted for why they
|
|
rebooted or logged off. Other problems should be logged as they happen.
|
|
|
|
If any machine can not access the server file for some reason, the
|
|
data is stored in c:\mttf.dat until the next time the server file is
|
|
opened. At such a time, the server file is updated and the local file
|
|
is deleted.

Increment the specified stat. For MTTF_TIME, check if it is busy

local data file. If server opened and local file also exists,

open local file also for transfer.

Search through data file for matching build number, add all values
