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. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Build Status

Datadog Cookbook

Chef recipes to deploy Datadog's components and configuration automatically.

Requirements

  • python >= 2.6
  • chef >= 10.12

Platform

  • Debian, Ubuntu, RedHat, CentOS

Cookbooks

The following Opscode cookbooks are dependencies:

  • apt
  • chef_handler
  • yum::epel

Attributes

  • node['datadog']['api_key'] = This needs to be retrieved from your Account Settings page.
  • node['datadog']['application_key'] = There are none by default. Visit the Account Settings page to create a new Application Key, to be used in conjunction with your API key.
  • node['datadog']['url'] = The location of where Datadog is hosted. Should never change.
  • node['datadog']['repo'] = Where the Datadog-maintained packages are located. Should never change.
  • node['datadog']['debug'] = Will trigger heavy logging to /tmp/dd-agent.log
  • node['datadog']['use_ec2_instance_id'] = Whether to use the instance-id in lieu of hostname when running on EC2. No effect on non-EC2 servers.
  • node['datadog']['use_mount'] = Whether to use the mount point instead of the device name for all I/O metrics.
  • node['datadog']['tags'] = List of Datadog tags you want to apply to this host
  • node['datadog']['dogstreams'] = List of Dogstreams (see Guide to Log Parsing for details).

apache

ganglia

  • node['ganglia']['url'] = Ganglia host where gmetad is running
  • node['ganglia']['port'] = Ganglia port where gmetad is running

graphite

  • node['datadog']['graphite'] = Turns the agent into a Graphite carbon relay.
  • node['datadog']['graphite_port'] = Port that the carbon relay will listen on.

haproxy

  • node['datadog']['haproxy']['stats_url'] = URL for haproxy stats
  • node['datadog']['haproxy']['stats_user'] = Optional HTTP Basic Auth user to access haproxy stats
  • node['datadog']['haproxy']['stats_password'] = Optional HTTP Basic Auth password to access haproxy stats

mysql

  • node['mysql']['server'] = MySQL host
  • node['mysql']['user'] = MySQL user. It only runs "SHOW STATUS" queries, which doesn't require any privileges, so you should consider creating a separate, unprivileged user.
  • node['mysql']['pass'] = MySQL user's password

postgres

  • node['postgres']['server'] = PostgreSQL host
  • node['postgres']['port'] = 5432 by default
  • node['postgres']['user'] = user that the agent will use to connect, "datadog" by default
  • node['postgres']['password'] = password to connect the datadog agent

Do not forget to update you pg_hba.conf and SIGHUP postgres in case your postgres access control requires it.

nginx

rabbitmq

mongodb

  • node['mongodb']['server'] = MongoDB uri. For example: mongodb://my_user:my_pass@localhost/my_db

couchdb

  • node['couchdb']['server'] = CouchDB host

jenkins

  • node['jenkins']['home_dir'] = Path to Jenkins's home directory

nagios

  • node['nagios']['log_dir'] = Path to Nagios's event log file
  • node['nagios']['conf_dir'] = If you use perfdata, dd-agent can import automatically and in real-time performance data collected by nagios. For more information on perfdata configuration, please refer to http://nagios.sourceforge.net/docs/3_0/perfdata.html. Path to Nagios' configuration file where the properties host|service_perfdata_file and host|service_perfdata_file_template are defined.

cassandra

  • node['cassandra']['host'] = Cassandra host
  • node['cassandra']['port'] = Cassandra port
  • node['cassandra']['nodetool'] = Path to nodetool

java

  • node['jvm_jmx']['server'] = JMX server:port to connect to
  • node['jvm_jmx']['user'] = JMX user to log in with, if needed
  • node['jvm_jmx']['pass'] = Password for the configured JMX user
  • node['jvm_jmx']['name'] = Name to report the statistics for this java VM. This will allow to monitor several JVMs running on the same machine.

tomcat

  • node['tomcat_jmx']['server'] = host:port to connect to. Must be configured in tomcat setenv.sh or similar
  • node['tomcat_jmx']['user'] = JMX user to log in with, if needed
  • node['tomcat_jmx']['pass'] = Password for the configured JMX user

varnish

  • node['varnish'] = if true, will invoke varnishstat on the server to gather varnish metrics.

memcached

  • node['memcached']['listen'] = memcached address; if 0.0.0.0 dd-agent will connect via the loopback address.
  • node['memcached']['port'] = memcached port

redis

  • node['redis']['server']['addr'] = redis server address
  • node['redis']['server']['port'] = redis server port

Recipes

default

Just a placeholder for now, when we have more shared components they will probably live there.

dd-agent

Installs the Datadog agent on the target system, sets the API key, and start the service to report on the local system metrics

dd-handler

Installs the chef-handler-datadog gem and invokes the handler at the end of a chef run to report the details back to the newsfeed.

Usage

  1. Add this cookbook to your Chef Server, either by installing with knife or downloading and uploading to your chef-server with knife.
  2. Add your API Key, either to attributes/default.rb, or by using the inheritance model and placing it on the node/
  3. Upload the new recipe via: knife cookbook upload datadog
  4. Associate the recipes with the desired roles, i.e. "role:chef-client" should contain "datadog::dd-handler" and a "role:somethingelse" should start the dd-agent with "datadog::dd-agent".
  5. Wait until chef-client runs on the target node (or trigger chef-client if you're impatient)

We are not making use of data_bags in this recipe at this time, as it is unlikely that you will have more than 1 API key.
