📙 Observability Notebook

A single source of truth of my learning journey of topics regarding observability engineering and SRE

📍 Repo Structure

In a nutshell, there are two main folders with different goals:

• notes: Notes that I took throughout my study routine, in which others can read for their own study purposes
• practice: Hands-on applications from what I learned throughout my study sessions

✏️ Notes Structure

Here's a concise summary of what you can expect from each notes subfolder

• observability: General concepts of observability, such as: definition, key areas, monitoring vs observability, cardinality
• logging: Specific notes around logging with code snippets of tools like Winston
• monitoring: Specific notes around monitoring, covering topics such as: Monitoring antipatterns, principles of monitoring design
• tracing: Specific notes around tracing, with code implementations and examples of using tools like Open Telemetry
