Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

ELK Build Status

ELK

This cookbook is the top level wrapper for the EverTrue ELK cookbook ecosystem

Requirements

  • et_elk Ties all the peices of an ELK cluster together
    • elk_forwarder Installs and Configures Logstash forwarder
    • elk_logstash Installs and Configures a central Logstash server
    • Leverages the logstash cookbook
    • elk_elasticsearch Installs and Configures an optimized Elasticsearch for use with Logstash
    • Leverages the elasticsearch cookbook
    • elk_kibana Installs and Configures Kibana for visualizing logs
    • Leverages the kibana cookbook

How do I actually use this system

1. Forwarders

You need to apply the client recipe to all your nodes. This will install and configure the Logstash Forwarder using elk_forwarder

2. Configure Forwarders

You then need to determine what logs you want to forward and you need to come up with a unique "type" to identify them. I.E. logs from rails app log files will have their type field set to rails_app.

From your Attributes

set['elk_forwarder']['config']['files']['myapp']['paths'] = ['/var/log/myapp.log']
set['elk_forwarder']['config']['files']['myapp']['fields']['type'] = 'myapp'
set['elk_forwarder']['config']['files']['myapp']['fields']['foo'] = 'bar'

Or from your recipe. This one loops through a list of apps

apps.each do |app|
  node.set['elk_forwarder']['config']['files']['myapp']['paths'] = ["/var/log/#{app}.log"]
  node.set['elk_forwarder']['config']['files']['myapp']['fields']['type'] = app
  node.set['elk_forwarder']['config']['files']['myapp']['fields']['foo'] = 'bar'
end

3. Write your pattern

We need to build a pattern(s) to add to evertrue_patterns.erb or another patterns template that you have setup. Grab a bunch of sample logs and use the Grok Constructor utility to construct a pattern that will match your logs. I usually find an existing pattern online and then tweak it to properly match the logs I am parsing.

Give your pattern a name like ET_PUPPIES_APP and add it to your patterns template.

4. Write your filter

This is pretty open ended, but here are the key requirements.

  • Checks the log's type field with an if condition
  • Groks the log with the pattern you just created
  • Parses a field containing some gross timestamp into the standard @timestamp field using the date filter. Note that the timestamp field is very different from @timestamp. timestamp is just a string extracted from the log which needs to be converted into a nice date/time.

Example:

filter {
  if [type] == "nginx_access" {
    grok {
      match => ["message", "%{ET_NGINXACCESS}"]
    }

    date {
      match => [ "timestamp", "dd/MMM/YYYY:HH:mm:ss Z" ]
      remove_field => [ "timestamp" ]
    }
  }
}

Once you have written your filter, save it to a new template and call the logstash_config resource with something like this in your cookbook's recipe

logstash_config 'nginx filter' do
  templates_cookbook 'yourcookbook'
  templates 'filter_nginx' => 'filter_nginx.erb'
  instance 'server'
end

And now you are shipping, recieving, groking, parsing, inspecting, mutating, indexing, and storing your logs!

Recipes

default

Installs everything on the node and configures it to be a central log server that recieves logs from the clients

  1. Install Elasticsearch, Logstash, and kibana
  2. Configure logstash with inputs and outputs using elk::server

client

Configures the node to be a client that ships logs to the central logstash server

  1. Install logstash-forwarder via elk_forwarder
  2. Configure logstash-forwarder to forward logs to central log servers
    • Central logstash servers are discovered via the node['et_elk']['logstash_discovery'] attribute
    • To Disable auto-discovery simply set node['et_elk']['logstash_discovery'] to ''

Usage

depends 'et_elk', '~> 1.0'
# To install and configure the forwarder

include_recipe 'et_elk::client'

# To install everything on the node

include_recipe 'et_elk::default'
