How to install Graphite on Vagrant with Chef

Here are some quick notes on installing Graphite on a Vagrant virtual machine using Chef recipes from GitHub. This more or less assumes you know what you're doing with Vagrant and Chef.

Notes

  • I used the "lucid32" Ubuntu base box you see in most Vagrant examples (http://files.vagrantup.com/lucid32.box)
  • Where possible, I used the cookbooks from Opscode. I was forced to use alternatives for Python (did not work for me) and for Graphite (no Opscode cookbook as of now).
  • The Graphite recipe depends on the Python, Apache2, and runit recipes.
  • I'm running the apt recipe first to update the Ubuntu package manager. The out-of-date manager that ships with the lucid32 box errored out for me when running the Python recipe.

Cookbooks Used

# Before we start, make sure you have Essex support in Fog
#
# Essex support has not been merged into upstream Fog so you'll need
# a custom ruby fog build to run through the examples

Tuning Nginx for heavy loading with nodejs as upstream. Short requests and a lot of concurrence.
# This number should be, at maximum, the number of CPU cores on your system.
# (since nginx doesn't benefit from more than one worker per CPU.)
worker_processes 8;
# Determines how many clients will be served by each worker process.
# (Max clients = worker_connections * worker_processes)
# "Max clients" is also limited by the number of socket connections available on the system (~64k)
# run ss -s and u'll see a timewait param
# The reason for TIMED_WAIT is to handle the case of packets arriving after the socket is closed.

Logstash Mapping 说明
curl -XPUT 'http://localhost:9200/_template/logstash_default' -d @/<path>/xxxx.json
# template的mapping和普通mapping略有不同
# 需要在settings前面增加一行
# 非常适合logstash的场景,所以本例中以logstash做sample。
