mod_measure_process: Report the enforced limit The soft limit is what the kernel actually enforces, while the hard limit is is how far you can change the soft limit without privileges. Unless the process dynamically adjusts the soft limit, knowing the hard limit is not as useful as knowing the soft limit. Reporting the soft limit and the number of in-use FDs allows placing alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

# Introduction

This module adds support for reading AWS IAM access credentials from EC2 instance metadata,
to allow Prosody modules to gain role-based access to AWS services.

# Configuring

``` {.lua}
modules_enabled = {
    "aws_profile";
}
```

There is no other configuration.

# Usage in other modules

Other modules can import the credentials as a shared table:

``` {.lua}
local aws_credentials = module:shared("/*/aws_profile/credentials");
do_something(aws_credentials.access_key, aws_credentials.secret_key);
```

Note that credentials are time-limited, and will change periodically. The
shared table will automatically be updated. If you need to know when this
happens, you can also hook the `'aws_profile/credentials-refreshed'` event:

``` {.lua}
module:hook_global("aws_profile/credentials-refreshed", function (new_credentials)
  -- do something with new_credentials.access_key/secret_key
end);
```

# Compatibility

Meant for use with Prosody 0.11.x, may work in older versions.
