Keep-It-Up (KIU) is a tool that keeps your Macintosh (server) apps up and running.
Keep It Up relaunches applications that crash or hang ("application not responding"), it can restart the Mac on a regular basis and it can monitor free disk space. It also allows you to remotely manage and monitor your Mac using a webbrowser. It works on MacOS X (Keep-It-Up-X) and MacOS 9 (Keep-It-Up Classic) and was written by Karl Pottie.
KIU has a tiny "embedded" webserver (running on a port of your choice) that allows you to remotely restart/shutdown the Macintosh ; view, kill or relaunch running applications;launch applications; run Applescripts; view logfiles generated by KIU or any other application; get some info about the system (free disk space, uptime, ...)
KIU can check if certain Network Services are still available by polling the network port and checking for a valid response. In case of failure, it can notify you via e-mail, relaunch the corresponding application or restart the Mac. This way you can monitor your webserver, ftpserver or application server (e.g. FileMaker Pro) and check if it is still serving data and doesn't hang.
KIU can send e-mail messages to you, actively alerting you of certain events.
KIU automounter will mount Appleshare volumes at startup and remount these volumes if your Mac gets disconnected from the Appleshare server is interrupted. An e-mail is sent when a volume is remounted or when the mount fails if the Appleshare server is unavailable. Read about the KIU features, the versions and the download sites here.
