Installs a mini monitoring environment based on Vagrant. Intended for development and monitoring of the monitoring infrastructure.

Installation

Get the Code

git clone https://github.com/hpcloud-mon/mon-vagrant

Vertica must be downloaded from the Vertica site. Download these packages and place in the root of this repository.

• vertica_7.0.1-0_amd64.deb
• vertica-r-lang_7.0.1-0_amd64.deb

The vertica::console recipe is not enabled by default, but if it is added, this package is also needed.

• vertica-console_7.0.1-0_amd64.deb

Install Vagrant

Install VirtualBox and Vagrant

Note: Vagrant version 1.5.0 or higher is required.

MacOS

The following steps assume you have Homebrew installed. Otherwise, install VirtualBox and Vagrant manually from their websites, then continue with Set Up Berkshelf below.

brew tap phinze/cask
brew install brew-cask
brew cask install virtualbox 
brew cask install vagrant

Linux (Ubuntu)

# For Ubuntu 12.04, you may need to install ruby 1.9 first
sudo apt-get install ruby1.9.3
sudo update-alternatives --set ruby /usr/bin/ruby1.9.1

sudo apt-get install virtualbox
latest=`curl -s http://www.vagrantup.com/downloads.html |tr " " "\n" |grep 'x86_64.deb' |cut -d'"' -f2`
wget $latest && sudo dpkg -i `basename $latest`

Set Up Berkshelf

MacOS

vagrant plugin install vagrant-berkshelf --plugin-version '>= 2.0.1'
gem install berkshelf

Linux (Ubuntu)

sudo vagrant plugin install vagrant-berkshelf --plugin-version '>= 2.0.1'
sudo gem install berkshelf

Using mini-mon

• Your host OS home dir is synced to /vagrant_home on the VM.
• The root dir of the mon-vagrant repo on your host OS is synced to /vagrant on the VM.
• The main VM will have an IP of 192.168.10.4 that can be access from other services running on the host.
• An additional VM running DevStack will be created at 192.168.10.5
• Run vagrant ssh <host> to log in, where <host> is either mini-mon or devstack
• Run vagrant help for more info

Updating

When someone updates the config, this process should allow you to bring up an updated VM.

• git pull
• berks update
• vagrant destroy <vm> Where <vm> is the name of the VM being updated, for example 'vertica'
• vagrant up

Improving Provisioning Speed

The slowest part of the provisioning process is the downloading of deb packages. To speed this up a local apt-cacher-ng can be used.

Linux (Ubuntu)

sudo apt-get install apt-cacher-ng

MacOS

brew install apt-cacher-ng

Run apt-cacher-ng -c /usr/local/etc/apt-cacher-ng/ or optionally follow the instructions from brew to start up the cache automatically. That is all that is needed. From now on, the cache will be used.

A report from the cache is found at http://localhost:3142/acng-report.html

Cookbook Development

To develop cookbook changes with Vagrant:

• Edit Berksfile, changing the appropriate cookbook line to a local path. For example:

cookbook 'zookeeper', path: '/Users/kuhlmant/src/mon/cookbooks/zookeeper'

• Edit your local cookbook as needed
• Run berks update <cookbook_name>
• If the Vagrant VM is already up, run vagrant provision. Otherwise, run vagrant up
• When finish testing commit and upload your cookbook as normal but don't forget to bump the cookbook version in the metadata.rb.

Running behind a Web Proxy

If you are behind a proxy you can install the vagrant-proxyconf pluging to have Vagrant honor standard proxy-related environment variables and set the VM to use them also.

vagrant plugin install vagrant-proxyconf

Alternate Vagrant Configurations

To run any of these alternate configs, simply run the Vagrant commands from within the subdir. Note that the Vertica debs must be copied (not symlinked) into the subdir as well. See the README.md in the subdir for more details.

• HPCloud subdir - Runs a VM in the HP Public Cloud rather than using VirtualBox
• split subdir - The various monitoring components split into their own VMs
• Baremetal - Actually not using Vagrant at all; see the baremetal fabric task in the utils directory
