OpenAPC is an APC (Advanced Process Control) solution that is highly flexible and configurable and covers a wide range of automation, visualization, and process control tasks from home control up to industrial automation. Control applications created with the OpenAPC editor's visual interface can perform several tasks dependent on how the application is configured and used. The application is available for many different platforms, so OpenAPC projects can be switched over to a different platform easily.
downtimed is a program that monitors operating system downtime, uptime, shutdowns, and crashes and records such events. At OS startup it logs information about previous downtime. It then periodically updates a time stamp file on the disk, which is used to determine the approximate time when the system was last up and running. During a graceful system shutdown, it records a time stamp in another file. The downtimes(1) command line tool can be used to inspect records of past downtime.
