当然，你可以使用Cacti做这样的事情。你可以用它来绘制任何东西。 http://docs.cacti.net/manual:087:3a_advanced_topics.1_data_input_methods# data_input_methods

Sure, you CAN use Cacti to do such things. You can graph just about anything with it. http://docs.cacti.net/manual:087:3a_advanced_topics.1_data_input_methods#data_input_methods

这听起来像你的问题，你想要一个监视和警报解决方案，而不只是一个图形解决方案。对于监视，警报和图形（虽然图表不像rrdtool和cacti那么有吸引力）我喜欢开源Hyperic产品（ http://www.hyperichq.com ）。还有Nagios，BigBrother和许多其他低成本/无成本选项。

It sounds though from your question that you want a monitoring and alerting solution, not just a graphing solution. For monitoring, alerting, and graphing (though the graphs are not nearly as attractive as rrdtool and cacti) I like the opensource Hyperic product(http://www.hyperichq.com). There is also Nagios, BigBrother and a host of other low cost / no cost options.
