The Importance of Tracking Exceptions

As a solo founder and app developer, launching and maintaining an app – any app – can be a significant undertaking. It may not seem like much at first but there is a lot of information that you need to keep track of and questions that need to be answered. Here are some questions I needed to have answered when building and launching my app, Scheduling:

  • Are my servers still up and doing what they’re supposed to do?
  • Are my users getting emails from the application?
  • Are my users experiencing any errors?

For the purposes of this article, I’m going to concentrate on the last question: Are my users experiencing errors? As you may have gathered from the fact that you’re reading this on the Exceptional blog, I use Exceptional to track errors in the application. There’s a lot you can extrapolate from simple exception tracking, though.

Even with a strict TDD methodology, errors happen in an application. In my experience working on both large and small scale applications, developers always miss a few possibilities for behavior of an application. This can happen for many reasons: apps run differently with a lot of data compared to a little data in development, users figure out new and interesting ways to use (read: break) your application, and more. Keeping track of, and responding to, these errors helps to give you something that’s difficult to come by in this day and age: focus.

During beta, Exceptional was my to-do list: I would keep track of and (separately) prioritize bugs that needed to be fixed based on the information in Exceptional. Closing the error in Exceptional would mean, for me, it was done and the affected users were contacted. I still occasionally use Exceptional as my to-do list, though the app is, at this point, stable enough that I don’t much need to.

If you’re a developer, exception tracking is useful for keeping track of regressions with a twist. I had one particular error that popped up in a few places. I fixed it three times in the course of a few days in different spots in the app. This was a sure sign that I needed to devote some time to refactoring.

Finally, quickly being informed of errors helps in customer service. You can pass in custom information to Exceptional and see it in the dashboard. I find this most useful with information such as passing an account name or user name/email. This can make proactive customer responses very easy and surprising. I had an issue early on in the official launch of Scheduling which resulted in a user seeing an error page. This is a bad thing™. I was able to proactively email the affected user within minutes letting them know that I was aware of the error and it was being fixed, along with apologizing for what happened. This goes a long way towards fostering good will.

Send Exceptions to GitHub Issues.

Last week we introduced a new service to Exceptional.  Account administrators can add  GitHub integration.  Our first GitHub integration lets users send exceptions to GitHub creating a GitHub Issue. 

We will be adding more features to the GitHub service in the coming months, if you have a suggestion a feature, send them to support@getexceptional.com .

Step 1. Goto Account -> Services.  Add GitHub. 

2. Add the github username / organisation name and it’s repro. 

— NOTE. You have to add your organization + repro name/repo.  e.g. exceptional/exceptional-app

3. Authorise the Exceptional to access your GitHub account. 

4. At the bottom of an individual exception you will see a link to ‘Send to GitHub’.  You can edit the Issue title and content, but it will be based on the Exception detail information. 

5. You can now view the exception on GitHub. Our roadmap includes  automatically closing the exception on Exceptional once it’s closed on GitHub.

iOS, Coldfusion, Flask, Pylons, and more

The Exceptional community has been prolific of late, producing many new Exceptional clients meaning that Exceptional is far from being a Rails only web application. Let’s take a run through what’s available…

iOS

Jörg Polakowski has created an excellent iOS client meaning that Exceptional can now catch and aggregate errors thrown by iPhone and iPad apps. You can find his client here on Github.

Coldfusion

Brian Lambert created a Coldfusion client for Exceptional, which is available again on Github.

Pylons

The guys at DataDog wrote their own Pylons client for Exceptional. Guess where you’ll find it? Github.

Flask

Jonathan Zempel wrote a client for the Python microframework Flask.

11 Supported envrionments

These 4 new clients means Exceptional can now catch errors in Rails 3, Rails 2, Rack, Ruby, Javascript, PHP, Django, iOS, Coldfusion, Pylons, and Flask. If you see a framework missing and are willing to help us out, have a look at our API  and drop us a line (des at getexceptional dot com) and we’ll talk further.

Meet our Customers 9

There are some very cool Exceptional customers featured in this round, from ticket tracking to HTML5 & audio all the way to health & fitness classes in Atlanta. 

Sifter

In Contrast, we’ve been using Sifter heavily for about a year. It’s a fantastic tool for tracking issues during software development. Obviously this is a competitive space, and it takes a lot to stand out. Sifter has a beautifully clean UI and crucially the “Create a ticket” workflow is so simple that your whole team will get onboard using it. A good measure of the quality of a web application is the amount of people who end up using it after a recommendation. For me Sifter is scoring very highly there.

Sounds good

Sounds good  is a online video sound editor, using the latest HTML5 technologies. You can upload any video, add any sound from their extensive sample gallery, or add your own sounds from your computer and experiment with the result right away in your browser. Once you are happy with the results, Sounds good renders the video for you. The most recent feature added is YouTube support letting you send your video straight to YouTube, but even cooler, add your own soundtrack to a YouTube video!. 

Sounds good is a great example of what’s possible using HTML5, try their simple demo to see how impressive it is. 

Cooleaf

Cooleaf is a marketplace for health & fitness instructors, and would-be students. Their beta roll-out covers Atlanta,  Georgia,  where they’ve secured partnerships with Atlanta’s leading providers of health/wellness services including Yoga Studios, Health Clubs, and Personal Trainers. 

As always, we’re happy to feature all Exceptional customers on our blog, if you’re interested in this, simply send a message to des at getexceptional.com

Exceptional engineer required

Exceptional tracks errors in Ruby apps. It’s wildly popular. It now processes a few hundred million errors per month for over 10,000 apps—including some very big and popular ones. Every day, new people add Exceptional to their apps. And increasingly, these apps are not even Ruby. They’re PHP, Javascript, Python and more.

Our rapid rate of growth requires some serious help. We’re looking for an excellent software engineer to manage and improve the product.

You must have:

  1. many years of Ruby (and Rails) experience and
  2. many years of database admin experience.

It would be nice if you also had:

  1. a computer science (or equivalent) education,
  2. great social skills and the right attitude to give our customers appropriately warm, fuzzy feelings.

Your responsibilities will include working with us to implement brand new features, dealing with technical enquiries from our customers, making fixes to the app, liaising with developers to help them build plugins for their technology of choice. You’ll work remotely.

In return, we’ll:

  1. retain you on contract for a fixed amount of days each week (starting with 3, growing to 5 before the end of the year),
  2. give you a cut of the profit.

This is a big deal. Exceptional has been run entirely by the Contrast team to-date and we’re ready to take it to the next level and give one talented and very able programmer a tonne of responsibility and control over the product. We’re doing this because we feel that Exceptional’s future will be brightest if driven by someone with fresh ideas and energy and not distracted by the other goings on in our team.

Please get in touch if you’re interested.

Recent Performance Issues

This e-mail was sent to all of our active users on 3 Feb 2011.

OUR RECENT PERFORMANCE ISSUES

Exceptional has had some severe performance issues over the past 5 days. For this we are incredibly sorry. We know Exceptional is a part of your workflow, and this past week we haven’t delivered a good service. We have fixed the problems that occurred, and we’ve now made many changes to speed Exceptional up. 

Nonetheless, developers to developers, we owe you an explanation…

WE EXCEEDED RDS STORAGE LIMITS

On the 28 January our main database ran out of storage space due to a truly massive, unprecedented spike in new exceptions—despite our API rate limiting. It hit the 1TB storage limit imposed by Amazon RDS on a single database instance. We attacked the problem in two ways: firstly implementing a sharding strategy, and secondly reclaiming space on the database.

WE NOW SHARD OUR DATA

Exception data is now sharded by app, meaning that the load on our most frequently accessed data (occurrence data) is now distributed across our database cluster. We’re also working hard to clean out extraneous data. The web app may have some short periods of downtime as a result of this improvement work, however, we’ll schedule it for the off-peak hours. As always, no exception data will be lost.

WE’RE SPEEDING UP THE WEB APP

We have improved the performance of the web application. You’ll notice that occurrence data is now loaded via AJAX, and is cached by the browser. This makes it easier to get straight to your exception data, and also speeds up all subsequent page loads. We’re quite pleased with the results of this, and we’re looking for ways to speed up the web app further.

API and web app performance should be better than ever before. We’ll aggressively monitor our storage capacities in the future, though our new architecture will give us much more scaleability and flexibility.

WE’RE GRATEFUL FOR YOUR SUPPORT

Thank you so much, for your time, patience, and custom.

Sincerely,

Ciarán, Wal, Eoghan, Des and David.
