This cookbook provides an easy way to install the Server Density agent.

Requirements

Cookbooks:

This cookbook has dependencies on the following cookbooks:

• apt
• yum::epel

Platforms:

• Ubuntu
• Debian
• RHEL
• CentOS
• Fedora

Attributes

Basic config

• node['serverdensity']['sd_url'] - Your Server Density subdomain, prefixed with either http:// or https://, required
• node['serverdensity']['agent_key'] - Your Server Density agent key (don't set this if you want to use the API to handle querying nodes/creating nodes)

API v1 config

If your account URL ends in .com you are using v1

Use this if you're still on Server Density v1 and wish to use the API to create nodes (rather than auto-copy templates):

• node['serverdensity']['api_version'] - Server Density API version to use (if agent_key isn't set), default: 1.4
• node['serverdensity']['api_v1_base_url'] - Base URL for the API (if agent_key isn't set), only override for testing API calls, default: https://api.serverdensity.com/
• node['serverdensity']['api_username'] - Username for authenticating with the v1 API (if agent_key isn't set)
• node['serverdensity']['api_password'] - Password for authenticating with the v1 API (if agent_key isn't set)

Optional API v2 config

If your account URL ends in .io you are using v2

If you don't set agent_key then set these parameters and new servers will be automatically created in your account.

• node['serverdensity']['api_version'] - Set to 2.0
• node['serverdensity']['api_v2_token'] - Your API token from Preferences > Security in Server Density.

Optional advanced config

• node['serverdensity']['device_group'] - Sets the group for the device to be created in, to inherit alerts automatically.
• node['serverdensity']['plugin_dir'] - Sets the directory the agent looks for plugins, if left blank it is ignored
• node['serverdensity']['apache_status_url'] - URL to get the Apache2 status page from (e.g. mod_status), disabled if not set
• node['serverdensity']['apache_status_user'] - Username to authenticate to the Apache2 status page, required if apache_status_url is set
• node['serverdensity']['apache_status_pass'] - Password to authenticate to the Apache2 status page, required if apache_status_url is set
• node['serverdensity']['mongodb_server'] - Server to get MongoDB status monitoring from, this takes a full MongoDB connection URI so you can set username/password etc. details here if needed, disabled if not set
• node['serverdensity']['mongodb_dbstats'] - Enables MongoDB stats if true and mongodb_server is set, default: false
• node['serverdensity']['mongodb_replset'] - Enables MongoDB replset stats if true and mongodb_server is set, default: false
• node['serverdensity']['mysql_server'] - Server to get MySQL status monitoring from, disabled if not set
• node['serverdensity']['mysql_user'] - Username to authenticate to MySQL, required if mysql_server is set
• node['serverdensity']['mysql_pass'] - Password to authenticate to MySQL, required if mysql_server is set
• node['serverdensity']['nginx_status_url'] - URL to get th Nginx status page from, disabled if not set
• node['serverdensity']['rabbitmq_status_url'] - URL to get the RabbitMQ status from via HTTP management API, disabled if not set
• node['serverdensity']['rabbitmq_user'] - Username to authenticate to the RabbitMQ management API, required if rabbitmq_status_url is set
• node['serverdensity']['rabbitmq_pass'] - Password to authenticate to the RabbitMQ management API, required if rabbitmq_status_url is set
• node['serverdensity']['tmp_directory'] - Override where the agent stores temporary files, system default tmp will be used if not set
• node['serverdensity']['pidfile_directory'] - Override where the agent stores it's PID file, temp dir (above or system default) is used if not set
• node['serverdensity']['plugin_options'] - A hash of optional named plugin options if you have agent plugins you want to configure, simple key-values will be added to the [Main] section of the config while sub-hashes will be generated into sections e.g. {"Beanstalk"=>{"host"=>"localhost"}} becomes:

[Beanstalk]
host = localhost

Usage

1. Include recipe[serverdensity] in a run list to implicly run recipe[serverdensity::install]

2. Then:

• Override the node['serverdensity']['agent_key'] attribute on a higher level. recommended
• or use the API to query for devices matching the node's hostname or create a new one if not found, by setting the config options.

3. As this cookbook depends on a few other cookbooks it's recommended you use a library like Berkshelf, librarian-chef or knife-github-cookbooks to automatically manage and install them.
