Here at AppNeta, we get to see a lot about how people build their web applications. From simple PHP scripts to heavily service-oriented Java clouds to monolithic Django apps, everybody’s product is architected a little differently. We’re still out to trace everything, and today I want to talk how to get visibility into an important component of any complex system: the messaging queue. Specifically, let’s look at how to trace a job from Rails using Resque. Messaging Queues If you haven’t used a messaging queue in your app, the idea is simple. Instead of forcing all the work to happen during the request, while the user is waiting, you can delay some of the more time-consuming tasks. You can do anything in these tasks, ranging from a simple insert to kicking off a series of user analytics that touch all parts of your infrastructure. The advantage is that you can retur... (more)

Caching: Up and Down the Stack

The other month I presented Caching Up and Down the Stack at the Boston Web Performance meetup. It was great to get the chance to present to the 60+ people who came out for the talk. Unsurprisingly, many of the people there knew a lot about caching in all of the different levels I touched on, and some great conversation developed. I covered six of the major areas of caching available to web devs today. On the HTML / JS / CSS side, you can use client asset caches, full-page HTTP caches (like Varnish) and partial template caches. On the back end, you can use generated code caches,... (more)

Tracing Python — An API

We’re pleased to announce a new Python instrumentation version — Oboeware 1.1! We’ve added a few new libraries recently, but we’re really excited about the new customization API we’ve introduced in this version. More than just a Python bump, this is the first package we’re releasing with an implementation of our new Oboe API. The Oboe API is a common set of idioms and metaphors for extending Tracelytics instrumentation or quickly writing your own from the ground up. We’re excited to get it out there, and we’re even more excited to see what you build with it! Conceptually, the O... (more)

TraceView Data API

I’m excited to announce a new feature to TraceView – the Data API! In a nutshell, the Data API exposes all of those high-level metrics you’re collecting in TraceView over REST, formatted as JSON. Now you can take that data, jam it into your own system and do whatever you need to make sure everybody in your organization sees what they need, when they need it. We’ve also wrapped our configuration API into the same place, so you can interact with all our services in one place. If you’re itching to get to it, head on over to the docs. If you’re still not convinced, read on! Let’s tak... (more)
