Application specific host grouping in Riemann-dash

It is generally desirable to group all the hosts for a specific service into a single dashboard view. For example, all the web servers are in single view while all the database servers are in another view.

This is usually not an issue when you are sending custom metrics using Riemann client. However, there are cases where you are using something that you do not control how the metrics are being sent. i.e., Riemann-tools.

Since Riemann-tools scripts are application agnostic, in order for the dashboard view to group hosts, we must inject some application specific information into the tags field. Tags is a collection of arbitrary strings. In the case of Riemann-tools scripts you can pass in arbitrary strings on the command line.

riemann-health --host 127.0.0.1 --tag "prod" --tag "webserver"

Unicorn memory usage improvement with Ruby 2.0.0

Here's a preliminary experiment to see how much memory is saved with the new copy-on-write friendly (bitmap marking) GC.

Calculated by memstats.rb https://gist.github.com/kenn/5105061 on Debian x86_64.

Master process:

# ./memstats.rb 20547

FunctioncallModule.java

private V8Function emit;
private V8Function gnee;

public FunctioncallModule() {
    super();
    System.loadLibrary("functioncall-utils");
    
    // create callback functions
    this.emit = new V8Function(createJSCallback("do_emit", "(Ljava/lang/Object;Ljava/lang/Object;)V"));

var debug = Debug.Debug

An addendum to CodeMirror's keyMap documentation, which unfortunately glosses over the 'connecting the wires' section.

CodeMirror.keyMap.tabSpace = {
    Tab: function(cm) {
        var spaces = Array(cm.getOption("indentUnit") + 1).join(" ");
        cm.replaceSelection(spaces, "end", "+input");
    },
    fallthrough: ['basic']
};
