$ gem install riemann-dash $ riemann-dash
Then open http://localhost:4567 in a browser. Riemann-dash will connect to the local host (relative to your browser) by default, and show you a small manual. Change the IP address in the top right field to point to your Riemann server's websocket port.
Riemann-dash takes an optional config file, which you can specify as the first command-line argument. If none is given, it looks for a file in the local directory: config.rb. That file can override any configuration options on the Dash class, and hence, all Sinatra configuration. You'll find a few usage examples in "example/config.rb".
set :port, 6000 # HTTP server on port 6000 set :bind, "22.214.171.124" # Bind to a different interface config[:ws_config] = 'custom/config.json' # Specify custom workspace config
You can also specify the default config file to be used by setting the
RIEMANN_DASH_CONFIG environment variable. If set, this value will override
the default config file location of
config.rb when no config file is passed
on the command line.
Putting in production
If you expect more than a couple of simultaneous users, you should consider running Riemann-dash in a proper application server. The easiest way is to install thin or puma. Riemann-dash will automatically use one of them if they are present. You'll need the C/C++ compiler, as well as the ruby and openssl libraries and headers installed.
$ gem install riemann-dash thin $ riemann-dash
Riemann-dash can also run in a web server supporting the Rack interface. An example rackup app is found in "example/config.ru".
$ git clone git://github.com/riemann/riemann-dash.git $ cd riemann-dash $ bundle
