Creating a dynamic site-to-site VPN with OpenSwan on Ubuntu 10.04 on EC2

Wes Winham [email protected]

There are many tutorials floating around the web that almost get you a dynamic VPN in EC2. The goal of this tutorial is to be a one-stop-shop for this specific setup.

logstash queries graphed with graphite.

Operation: Decouple whisper from graphite.

Method: Create a graphite function that does a date histogram facet query against elasticsearch for a given query string for the time period viewed in the current graph.

Reason: graphite has some awesome math functions. Wouldn't it be cool if we could use those on logstash results?

The screenshot below is using logstash to watch the twitter stream of keywords "iphone" "apple" and "samsung" - then I graph them each, so we get an idea of popularity. As a bonus, I also do a movingAverage() on the iphone curve to show you why this is awesome.

Sensu Scheduled Downtime Event Annotation

As part of helping a customer develop their proof of concept monitoring system with Sensu Enterprise, I worked up a mutator which uses stash data to determine if an event occurred within a pre-defined maintenance window.

The idea here is that event data needs to be annotated to indicate whether an event occurred during a scheduled maintenance window for SLA reporting purposes. With this added downtime context, events logged to an external source (e.g. greylog, elasticsearch) via Sensu Enterprise event bridge should provide enough information to determine whether or not a client's check result matches a scheduled downtime window.

Please note that I have done very little in the way of testing so this plugin is not likely to be very robust. Since this mutator probably needs to be applied to every event, it should probably be implemented as an extension before being put into a production system.
