README.md

Install's a mini monitoring environment based on vagrant. Intended for development and monitoring of the monitoring infrastructure.

Usage

Get the Code

git clone https://git.hpcloud.net/mon/mini-mon.git

Setup Vagrant

Install Vagrant

Assumes you have home homebrew installed, if not download and install VirtualBox and Vagrant from their websites then continue with Setup Berkshelf.

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

Setup Berkshelf

vagrant plugin install vagrant-berkshelf
gem install berkshelf  or gem install --http-proxy <http://some-proxy.foo.com:8088> berkshelf

Using mini-mon

  • Your home dir is synced to /vagrant_home on each vm
  • Vms created
    • api at 192.168.10.4
    • kafka at 192.168.10.10 - mon-notification runs on this box also
    • mysql at 192.168.10.6
    • persister at 192.168.10.12
    • thresh at 192.168.10.14
    • vertica at 192.168.10.8
  • Run vagrant help for more info
  • Run vagrant ssh <vm name> to login to a particular vm
  • Can also run ssh vagrant@<ip address> to login
    • password is vagrant

Start mini-mon

Berkshelf will download some cookbooks from the community so http_proxy and https_proxy environment variables must be set if applicable. From within the mini-mon directory, to start all the vms run:

bin/vup

The standard vagrant commands can also be used, the vup script just starts things up in a dependency order using parallel startup.

Halt mini-mon

In some cases halting mini-mon can result in certain vms being left in an odd state, to avoid this a script has been made to halt boxes in the correct order

bin/vhalt

Updating a VM

When someone updates the config for a vm 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 vm

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. To install on a mac

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
