I've been playing around with trying to make it as simple as possible to start logging a few metrics with as little effort in setup as possible.
As I was working on Papertrail I came up with a couple interesting ideas, some of which were inspired by OpenTSDB.
In this example we are pretending we're processing emails as background jobs and would like to track how many we've sent over time.
| Vagrant::Config.run do |config| | |
| # Use the Opscode box that we downloaded. | |
| config.vm.box = "chef-ubuntu" | |
| # Let's give the box an IP that is accessible by the other nodes we | |
| # will spin up. | |
| config.vm.network "33.33.33.11" | |
| # Forward the Riak HTTP and Protobufs ports so we can access them | |
| # locally. |
| Vagrant::Config.run do |global_config| | |
| aptdir = (ENV['APTCACHE'] or "#{ENV['HOME']}/aptcache/") | |
| checkout = (ENV['COOKBOOKS'] or "#{ENV['HOME']}/openstack-cookbooks") | |
| ip_prefix = (ENV['IP_PREFIX'] or "192.168.76.") | |
| mac_prefix = (ENV['MAC_PREFIX'] or "080027076") | |
| fixed = (ENV['FIXED'] or "10.0.76.0/24") | |
| global_config.vm.define :chef do |config| | |
| suffix = "100" | |
| ip = "#{ip_prefix}#{suffix}" | |
| config.vm.box = "base" |
| 15:15 <jiboumans> i just noticed somethign really strange: i do a get on a key, get a 404. | |
| this key was previously returned from a listkeys operation, so i know it's htere. I do the get *again* and it | |
| returns the object: http://pastebin.com/3T561WAF. what bizarre issue am i running into? | |
| 15:16 <jiboumans> the only thing I can think is special about this setup is that this node is normally | |
| in a cluster of 4, but the other 3 instances do not have riak running at the moment | |
| 15:16 <seancribbs> jiboumans: read-repair | |
| 15:16 <jiboumans> seancribbs: i dont know what that means. is this some riak-admin command? |
The best way to use this tool is to hook apt's use of dpkg to run it before doing any package installs.
In your apt.conf, put this:
DPkg::Pre-Install-Pkgs {"xargs -rL1 bash /path/to/stripdeb.sh 2>&1 | logger -t stripdeb"}
Then, a demo:
% sudo apt-get install mysql-server-5.1
| class Chef | |
| class Provider | |
| class RemoteS3File < Chef::Provider::RemoteFile | |
| def load_current_resource | |
| super | |
| %w{bucket object_name aws_access_key_id aws_secret_access_key}.map do |attribute| | |
| Chef::Application.fatal! "remote_s3_file: required attr: #{attribute} is nil", -92 if | |
| @new_resource.send(attribute.to_sym).nil? | |
| end |

| 15:51 <fujin> yo guys | |
| 15:52 <fujin> is there a way to automatically cluster Riak via similar method to rabbitmq_cluster.config? | |
| A list of node@sname terms, if I'm not mistaken. | |
| 15:52 <fujin> I'm levelling up benblack's shit. | |
| 15:54 <fujin> oh | |
| 15:54 <fujin> disregard |
