downtimed is a program for monitoring operating system downtime, uptime, shutdowns and crashes and for keeping record of such events.
downtimed(8) is a daemon process which is intended to be started automatically from system boot scripts every time when the operating system of a server starts. First the daemon logs its findings about the previous downtime to a specified logging destination as well as in a database file which can be displayed with downtimes(1) command.
Thereafter the downtimed(8) daemon just keeps waiting in the background and periodically updates a time stamp file on the disk. The time stamp is used to determine the approximate time when the system was last up and running. In case of a graceful system shutdown it records a stamp to another file on the disk. These files are used for reporting the next time the daemon starts.
downtimes(1) is a command-line tool which can be used to inspect previous downtime records recorded in the downtime database file.
This sofware works on GNU/Linux, FreeBSD, NetBSD, OpenBSD, Mac OS X and Solaris based operating system distributions. It can be ported to other modern UNIX-like operating systems relatively easily. The software is available under Simplified BSD license.
