s3stat 1.0.2

S3 Stat
=======

This python module uses the really nice `goaccess <http://goaccess.prosoftcorp.com/>` utility
to provide you with an amazing Amazon log file analyser tool that is relatively easy to install, and is extremely
easy to extend.

Installation
-------------

::

pip install s3stat

This installs `s3stat.py` in your PYTHONPATH in case you would like to run it from the command line.

Quickstart
------------

Generating an AWS user
........................

First you should create a user that has approriate rights to read your log files, and you should have its AWS access keys ready.

# Log in to the `aws console <https://console.aws.amazon.com/iam/home?#users>`
# Create a new user and select the option to generate an access key for the user
# Save the access key and secure keys, as these will be needed soon
# Open the *Permissions* tab for the user, and attach a new user policy.
Select custom policy, and copy the following::

{
"Statement": [
{
"Sid": "Stmt1334764540928",
"Action": [
"s3:GetBucketAcl",
"s3:GetBucketLogging",
"s3:GetObject",
"s3:ListAllMyBuckets",
"s3:ListBucket",
"s3:PutBucketAcl",
"s3:PutBucketLogging",
"s3:PutObject",
"s3:PutObjectAcl"
],
"Effect": "Allow",
"Resource": [
"arn:aws:s3:::*"
]
},
{
"Sid": "Stmt1334764631669",
"Action": [
"cloudfront:GetDistribution",
"cloudfront:GetDistributionConfig",
"cloudfront:GetStreamingDistribution",
"cloudfront:GetStreamingDistributionConfig",
"cloudfront:ListDistributions",
"cloudfront:ListStreamingDistributions",
"cloudfront:UpdateDistribution",
"cloudfront:UpdateStreamingDistribution"
],
"Effect": "Allow",
"Resource": [
"*"
]
}
]
}

Set up logging in your buckets
...............................

First you should ask Amazon to generate logs for your buckets and cloudfront distributions.

Run this script
................

::

s3stat.py <aws key> <aws secret> <bucket> <log_path>

This will download all the log files for today, and start a goaccess instance in your console.

For further options you might run::

s3stat.py -h

Extending
----------

Actually s3stat was designed to be easy to add to your pythonic workflow, as a result it defines
a single class that you can subclass to process the results in json format.::

import s3stat

class MyS3Stat(s3stat.S3Stat):

def process(self, json):
print json

mytask = MyS3Stat(bukcet, log_path, for_date, (aws_key, aws_secret))
mytask.run()

Where the `aws_*` parameters are optional, if missing then they are taken from the environment variables as provided by boto.

ToDo
-----

* provide a command that adds logging to specified buckets and cloudfront distributions
