OverCR software is a network daemon that utilizes a condensed, simple, human-readable query language to gather system metrics. System Monitoring is an important and expensive task. Fortunately free tools such as Big Brother have become available. Unfortunately these tools are not free in the GNU sense.
In addition the shell script format of Big Brother leaves something to be desired in my opinion. Therefore I've started writing Over-CR, a GPL Network Monitoring software. OverCR is probably most commonly used as a Netsaint (now Nagios) plugin.
Simply add it to your initialization scripts so that it starts on boot-up.
