AWS CloudWatch Client Package

aws.cloudwatch is a simple client package for the Amazon Web Services AWS CloudWatch REST API, which can be used to monitor use of AWS web services.

To use the package, you will need an AWS account and enter your credentials into R. Your keypair can be generated on the IAM Management Console under the heading Access Keys. Note that you only have access to your secret key once. After it is generated, you need to save it in a secure location. New keypairs can be generated at any time if yours has been lost, stolen, or forgotten.

By default, all cloudyr packages look for the access key ID and secret access key in environment variables. You can also use this to specify a default region or a temporary "session token". For example:

Sys.setenv("AWS_ACCESS_KEY_ID" = "mykey",
           "AWS_SECRET_ACCESS_KEY" = "mysecretkey",
           "AWS_DEFAULT_REGION" = "us-east-1",
           "AWS_SESSION_TOKEN" = "mytoken")

These can alternatively be set on the command line prior to starting R or via an Renviron.site or .Renviron file, which are used to set environment variables in R during startup (see ? Startup).

If you work with multiple AWS accounts, another option that is consistent with other Amazon SDKs is to create a centralized ~/.aws/credentials file, containing credentials for multiple accounts. You can then use credentials from this file on-the-fly by simply doing:

# use your 'default' account credentials
aws.signature::use_credentials()

# use an alternative credentials profile
aws.signature::use_credentials(profile = "bob")

Temporary session tokens are stored in environment variable AWS_SESSION_TOKEN (and will be stored there by the use_credentials() function). The aws.iam package provides an R interface to IAM roles and the generation of temporary session tokens via the security token service (STS).
