Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

• controller entry points with parameter values
• permanent information about the user, like user_id
• transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

##Instructions for downloading, compiling, and parsing KISSmetrics data exports by event

####Summary: The KISSmetrics data export feature does not allow users an easy way to analyze data by event. This Gist outlines instructions for downloading and parsing KISSmetrics data for event-level analysis.

#####Step 1: Export data from KISSmetrics

Set up AWS S3 bucket.

kivanio

km-export-processor gem

The purpose of this gem is to consume the JSON that KISSmetrics exports to an S3 bucket, and transform it in a variety of useful ways.

The core features are:

• JSON compiler : Aggregates all KISSmetrics JSON files in a directory, into a single (nonstandard) file.
• JSON to JSON converter : Converts a nonstandard JSON file into standard format.
• JSON to CSV converter : Converts a nonstandard JSON file into a CSV file, where each row is an event/property/alias.
• Reimporter : Takes a nonstandard JSON file, and an API key, and sends the data in the JSON file to the product using the KMTS gem.
