Great Expectations : Observability in asynchronous systems using temporal logic
This talk will focus on building observability across microservices.
The main focus will be on
1. Challenges faced while monitoring flows in asynchronous systems
2. Building on temporal logic constructs to verify system objectives
3. The concept of an expectation applied to detect failures in critical flows
- 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
To get the most out of the talk, experience in the following will help
1. Basic understanding and use of monitoring tools (Any kind).
2. Understanding of event sourcing
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.
