Episode 1 - What is Open Telemetry?

Hi. This is Tamimi. A developer advocate at Solace and welcome  to Tamimi’s Tidbits where we present short videos explaining technical concepts. Today we are  starting a new series that talks about Distributed Tracing in Event-Driven Architecture. Let’s start  with the basics and talk about Open Telemetry. Open Telemetry, or what is known  as OTEL is simply an observability framework to collect and export telemetry data. Observability is broken down  into three main components: We got metrics -

and these are numeric  measurements such as percent CPU usage, or aggregated measurements over time  such as a count to the number of events. Logs - and you can think of this telemetry data as timestamped records which could  either be structured or unstructured. And finally traces - focuses on the big picture of what happened to an event made  by an Application, user, or API Now if we want to look at a bigger picture of the  whole system, this is where Distributed Tracing comes in. It shows the

journey an event takes  through multiple hops in a distributed system. This is done through a process where  the context of an event that occurred is propagated between services and processes. It is important to note that OpenTelmetery  is an industry standard and Vendor agnostic. Now that we covered the basic  principles of open telemetry. Next, we will delve into how does Opentelemetery work
