README for Cricket version 1.0.5 ================================ 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. To use Cricket you need to do these things: * make a config tree * setup the collector to run on a regular basis * setup the grapher to let you look at the data Installing ---------- If you are a brand new Cricket user, you should read and closely follow the directions in doc/beginner.html. Upgrading ---------- (1) Read the CHANGES file to see what's new with this version. (2) Install this version to a separate directory from your existing version. (3) Copy subtree-sets and cricket-conf.pl from the existing version to this installation. Alternatively, rename this version cricket-conf.pl.sample to cricket-conf.pl and edit the file to match your settings from the cricket-conf.pl existing version. (4) Other potential pitfalls: If you use subtree timing info, you will need to edit collect-subtrees to set $subtreeTimes = 1. If you have placed custom images in cricket/images, you will need to copy these files from the existing version to this installation. (5) Cutover to this installation from your existing one by swapping the $HOME/cricket softlink to this version. (6) Recompile your config tree. (7) Run the collector or collect-subtrees by hand once to make certain it's still working. (8) Now you are ready to start experimenting with the new features described in the CHANGES file. Documentation ------------- Point your web browser at the doc/index.html file and choose the most appropriate document from there. Patches ------- If you manage to add a useful feature to the code (or need to make a bugfix just to get it running) please share a patch with the Cricket community, or consider becoming a Cricket developer and adding your code in to the next release. You can generate a patch like this: tar xvf cricket.tar mv cricket my-changes # make your changes to this this copy tar xvf cricket.tar gnudiff -u -r cricket my-changes This will create a unified context diff from the dist directory to the "my-changes" directory. It will allow people to apply your changes to their copies of Cricket.
