Exploring Cricket

Cricket is essentially an interpreted, rather than binary, package, but we strongly advise using prebuilt packages in whichever Linux distribution you choose. One option is to implement the Cricket home page's current TGZ (tarred and g-zipped) package--version 1.0.5, at this writing--but if you're a newbie, use an RPM with the up2date or yum command for Red Hat, apt-get for Debian, to install the latest and greatest Cricket image.



When installing Cricket on a Debian system, make sure the Apache Web server is loaded, then use the command apt-get install cricket. You shouldn't have to modify /etc/apt-get/sources.list--the default should work fine.

How It Works

Cricket polls devices at user-defined intervals, collecting pre-defined SNMP OIDs (object identifiers). It feeds that data to RRDTool, a "round-robin" database that keeps recent data and rolls up older data into averages over time, such as five-, 15- or 60-minute intervals. Cricket uses RRDTool's graphing functionality to display the graphs over the Web server on the host.
