Requirements

Platform:

• Ubuntu/Debian

Attributes

• node[:cw_mon][:user] - the user to run the script as. Created if necessary. Defaults to cw_monitoring.
• node[:cw_mon][:group] - the group the files should belong to. Defaults to cw_monitoring.
• node[:cw_mon][:home_dir] - the directory to install the scripts in. Defaults to /home/#{node[:cw_mon][:user]}
• node[:cw_mon][:version] - the version of the scripts to install. Defaults to 1.1.0
• node[:cw_mon][:release_url] - the URL to download from. Defaults to http://ec2-downloads.s3.amazonaws.com/cloudwatch-samples/CloudWatchMonitoringScripts-v1.1.0.zip
• node[:cw_mon][:aws_users_databag] - the encrypted databag containing the AWS key. See section below for details. Defaults to aws_users
• node[:cw_mon][:access_key_id] - the AWS access key id the script should authenticate with. See section below for details.
• node[:cw_mon][:secret_access_key] - the AWS access key the script should authenticate with. See section below for details.
• node[:cw_mon][:options] - the list of options to pass to the script. By default, all options are included: --disk-space-util --disk-path=/ --disk-space-used --disk-space-avail --swap-util --swap-used --mem-util --mem-used --mem-avail

Usage

Put recipe[cloudwatch_monitoring] in a run list, or include_recipe 'cloud_watch_monitoring' to ensure that the CloudWatch script is installed and cron'ed on your systems.

AWS authentication

with IAM role (recommended)

If your instance has an IAM role, then the script will use it to and you don't have to worry about setting keys.

Make sure that the role has permissions to perform the Amazon CloudWatch PutMetricData operation.

with a key

If your instance does not have a role, you need to specify a key. This can be done in 2 ways:

1. using the encrypted data bad specified by node[:cw_mon][:aws_users_databag]. That bag must contain an item for node[:cw_mon][:user] with 2 attributes: access_key_id and secret_access_key
2. using the node attributes: node[:cw_mon][:secret_access_key] and node[:cw_mon][:secret_access_key]

If the key get be loaded from the databag, the node attributes will be used.

Make sure that the user associated to the key has permissions to perform the Amazon CloudWatch PutMetricData operation.
