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"

Introduction

This script lets you set up and use a temporary DigitalOcean droplet to download torrent files.
Once downloaded, they can be streamed down to your local machine.
This uses transmission-cli for the torrent client, and nginx to serve files.

Setup on Local Machine

This assumes that you have a DigitalOcean account and tugboat set up, as well as seedbox-setup.sh present in the current directory.

Usage: ./docker.sh [base-image-name]

This is a temporary workaround to have etcd listening on all interfaces so you can access it from docker containers.

Add a local etcd unit file

Create a file called /media/state/units/etcd-local.service that has the following contents:

[Unit]
Description=etcd local

	{ "path": "/content/geometrixx/my-first-jinja-page",
	"properties": [
	{ "name": "jcr:primaryType",
	"value": "cq:Page" }],

	"nodes": [
	{ "path": "jcr:content",
	"properties": [
	{ "name": "jcr:primaryType",
	"value": "cq:PageContent"},

	<!DOCTYPE html>
	<meta charset="utf-8">
