1. Program for collection and display of time-series data This is Cricket. It is a configuration, polling, and data-display engine wrapped around the RRD tool by Tobias Oetiker. There are three user-visible pieces to Cricket: the collector, the grapher, and the config tree. The collector runs from cron and fetches data from a number of devices according to the info it finds in the config tree. The grapher is a CGI application that allows users to traverse the config tree from a web browser and see the data that the collector recorded. From Debian 3.0r0 APT
