OverCR

OverCR software is a powerful network daemon that uses a simple and easy-to-understand query language to collect important system metrics. System monitoring is an essential yet often expensive task, but with the availability of free tools like Big Brother, it has become more accessible than ever. However, these tools are not always free in the GNU sense, and the shell script format of Big Brother can be cumbersome and inefficient.

To address these issues, the developers of OverCR have created a GPL network monitoring software that is versatile, efficient, and easy to use. While it can be used in a variety of applications, it is most commonly used as a Netsaint (now Nagios) plugin.

Installation is simple and straightforward - all you need to do is add it to your initialization scripts so it starts on boot-up. For greater security, it is recommended that you run it as a non-root user via "su."

OverCR comes equipped with a range of useful commands that allow you to monitor various aspects of your system. For example, the "netstat" command enables you to monitor the number of connections to a specific TCP/IP port, while the "process" command allows you to track which processes are running. Other commands include "diskspace" (which allows you to monitor file system utilization), "uptime" (which reports on system uptime), "load" (which monitors system load over time), and "version" (which tells you which version of the OverCR collector you are running). Finally, the "postel" command pays tribute to Jon Postel, founder of the Internet, and reports his date of death.

Overall, OverCR is a reliable and versatile software program that is well suited to a wide range of system monitoring applications. Recent updates have fixed minor issues, making it an even more powerful and useful tool for IT professionals and enthusiasts alike.
