Coding Blocks

Coding Blocks

The world of computer programming is vast in scope. There are literally thousands of topics to cover and no one person could ever reach them all. One of the goals of the Coding Blocks podcast is to introduce a number of these topics to the audience so they can learn during their commute or while cutting the grass. We will cover topics such as best programming practices, design patterns, coding for performance, object oriented coding, database design and implementation, tips, tricks and a whole lot of other things. You'll be exposed to broad areas of information as well as deep dives into the guts of a programming language. While Microsoft.NET is the development platform we're using, most topics discussed are relevant in any number of Object Oriented programming languages. We are all web and database programmers and will be providing useful information on a full spectrum of technologies and are open to any suggestions anyone might have for a topic. So please join us, subscribe, and invite your computer programming friends to come along for the ride.... Show More

We’re using telemetry to fill in the gaps and anticipate problems while discussing The DevOps Handbook, while Michael is still weird about LinkedIn, Joe knows who’s your favorite JZ, and Allen might have gone on vacation.

    Once we have telemetry in place, we can identify any gaps in our metrics, especially in the following levels of our application:

  • Business level – These are metrics on business items, such as sales transactions, signups, etc.
  • Application level – This includes metrics such as timing metrics, errors, etc.
  • Infrastructure level – Metrics at this level cover things like databases, OS’s, networking, storage, CPU, etc.
  • Client software level – These metrics include data like errors, crashes, timings, etc.
  • Deployment pipeline level – This level includes metrics for data points like test suite status, deployment lead times, frequencies, etc.
  • Application and Business Metrics
  • Gather telemetry not just for technical bits, but also organizational goals, i.e. things like new users, login events, session lengths, active users, abandoned carts, etc.
  • Have every business metric be actionable. And if they’re not actionable, they’re “vanity metrics”.
  • By radiating these metrics, you enable fast feedback with feature teams to identify what’s working and what isn’t within their business unit.
  • Infrastructure Metrics
  • Need enough telemetry to identify what part of the infrastructure is having problems.
  • Graphing telemetry across infrastructure and application allows you to detect when things are going wrong.
  • Using business metrics along with infrastructure metrics allows development and operations teams to work quickly to resolve problems.
  • Need the same telemetry in pre-production environments so you can catch problems before they make it to production.
  • Overlaying other Relevant Information onto Our Metrics
  • In addition to our business and infrastructure telemetry graphing, you also want to graph your deployments so you can quickly correlate if a release caused a deviation from normal.
  • There may even be a “settling period” after a deployment where things spike (good or bad) and then return to normal. This is good information to have to see if deployments are acting as expected.
  • Same thing goes for maintenance. Graphing when maintenance occurs helps you correlate infrastructure and application issues at the time they’re deployed.
