dog not god is a server health monitoring tool for *nix based servers. The focus is on simplicity and on a 100% ruby implementation.

gem sources -a http://gems.github.com
sudo gem install spoonsix-dognotgod
sudo gem install spoonsix-dognotgod-client

The server captures performance data, and presents it via a web based interface.

dognotgod start

This will kick off a thin server on port 4567. It will also create the folder ~/.dognotgod and store the SQLite database at this location.

The client sits on the target machine - the machine to be monitored - captures performance data and sends it to the server. Note that this works on the machine acting as the server as well.

crontab -e
*/1 * * * * /path/to/dognotgod-client -a server-address -p port >> /dev/null 2>&1

This will run the client every minute. By default, the server-address is 127.0.0.1 and the port is 4567.
