Great Expectations : Observability in asynchronous systems using temporal logic

Submitted Mar 5, 2019

Section: Full talk of 40 mins duration Technical level: Intermediate Category: Monitoring and logging Section: Full talk (40 mins)

This talk will focus on building observability across microservices.
The main focus will be on

Challenges faced while monitoring flows in asynchronous systems
Building on temporal logic constructs to verify system objectives
The concept of an expectation applied to detect failures in critical flows

Outline

Challenges of monitoring asynchronous systems
What is an expectation ?
- Parts of an expectation
- Basics of a state machine
- Basics of linear temporal logic
- How it all fits together
Instrumenting the Expectation engine - with a description of components and reason for choice
Variations of the basic expectation in context with real world examples
Success stories where other monitoring systems would be insufficient
Challenges faced and how we overcame them

Requirements

To get the most out of the talk, experience in the following will help

Basic understanding and use of monitoring tools (Any kind).
Understanding of event sourcing

Speaker bio

I work at Capillary as a Principal Engineer and am actively involved in scaling our platforms. For over a decade i’ve been working on systems at scale, watching many of them closely as they grow, trying to eliminate every last bit of inefficiency. In the process, i’ve built up a good understanding of systems and pros and cons of various monitoring tools and processes.
