Additional usage information is available in the usage guide in docs/USAGE.md and the help subcommand output.

ec2rl can be run with no options or special configuration:

ec2rl run

Some modules require sudo/root. If executing as a regular user, utilizing sudo is required in order to run these modules:

sudo ec2rl run

Many modules require arguments for their usage. For example, most performance metric collection modules require times (number of samples to take) and period (length of sample).

sudo ec2rl run --times=3 --period=5

Some modules may negatively impact system performance and will not run by default. These modules can be run by specifying the perfimpact argument.

sudo ec2rl run --times=3 --period=5 --perfimpact=true

Modules are YAML files containing either a BASH or a Python script as well as the necessary metadata. Examples are available in mod.d and the module development guide found in docs/MODULE.md

It is recommended the resulting data be reviewed prior to being uploaded in order to ensure that no confidential information is included.

SSL SNI (Server Name Indication) is required for the ec2rl's upload functionality, however, this wasn't added to Python 2.7 until 2.7.9. See PEP 466 for more information regarding the SSL changes in Python 2.7.9.

Python's curses module is normally built into its standard library, however, it is sometimes separated and included as a separate package. You will need to install it with the operating system's package manager. The package name in SUSE Linux Enterprise Server 12 is "python-curses".
