The meetup will be held in person (finally!!) at Logz.io Offices, 28 Ha'arba'a street, Tel-Aviv - Hagag Northern Tower, 30th floor 

Agenda:

Mingling from 17:30, talks will start 18:00.

On this meetup we'll focus on Observability, with great talks

- Observability overview – Dotan Horovits, Logz.io

- Improving Observability of Distributed Systems – David Ostrovsky, Proofpoint

- OpenTelemetry, Not Only for Production – Michael Haberman, Aspecto

Talk details:

Observability Overview

What is Observability? how is that different than monitoring? how can it serve DevOps when using containers and microservices environments?
Dotan will set the stage with common terms and concepts to set the stage for this meetup's excellent talks.

Dotan Horovits 

Dotan is an avid advocate of open source software and communities. Dotan runs the OpenObservability Talks podcast, he co-organizes the CNCF Tel Aviv meetup group, the Developer Community TLV event and other local communities. Currently working as a developer advocate at Logz.io, Dotan evangelizes on Observability in IT systems using popular open source projects such as ELK stack, Prometheus, Grafana, Jaeger and OpenTelemetry.

Improving Observability of Distributed Systems

Tell me if this sounds familiar: you have a web service, that calls another service, that sends a Kafka message to a third service, that writes something to a database. Except sometimes it doesn’t. Where did the message go? Did the client not send it? Or did Kafka eat it? You don’t know. You look in the logs, but there are so many logs! You try to reproduce the problem but, annoyingly, everything works fine. What to do?

In this talk we’ll explore mechanisms for observing and debugging distributed systems with an eye towards taking an existing codebase that lacks observability and evolving it over time. We’ll discuss various technologies and tools that can help us solve specific business problems around stability, latency, and uptime. We’ll look at various examples of how Proofpoint tackled issues with observability in its cloud security product over the past 3 years, what worked well, and what didn’t.

David Ostrovsky

At age 9 little David found a book in Russian called “Electronic Computational Machines” at the library and, after reading it in a single weekend, decided that this was what he wanted to do with his life. Three years later he finally got to touch a computer for the first time and discovered that it was totally worth the wait. One thing led to another and now he’s an architect at Proofpoint. David is a software developer with over 20 years of industry experience, speaker, trainer, blogger and co-author of “Pro Couchbase Server”. He specializes in distributed system architectures and exotic databases.

OpenTelemetry, Not Only for Production Troubleshooting: How to Prevent Downtime as Early as Local Dev

OpenTelemetry is a great tool for observability and debugging in production. It provides you with data that empowers you to understand what is slow or broken and what you can do to solve it.
What if we could leverage OpenTelemetry capabilities during pre-production? What if you could use it during development and testing phases to prevent your next downtime?
In this talk, we’ll show you how to leverage OpenTelemetry to gather and analyze data from production and how to use it in pre-production workflows to help developers troubleshoot microservices, validate their changes, and prevent issues before they get to production. After this session, you’ll know how to use OpenTelemetry data to become proactive rather than reactive.

Michael Haberman

Michael is the Co-Founder and CTO of Aspecto. After serving as a software developer in an elite unit in the Israeli Intelligence branch, Michael worked with a few startups on building and scaling their microservices infrastructure. Prior to co-founding Aspecto, he was the Chief Architect at Playbuzz. In his free time, Michael also lectures and conducts workshops on microservices at conferences.

Meetup will be held in Hebrew.
