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.
