Abstract

Observability is a:

• monitoring
• logging (e.g. syslog)
• debuggers, profilers
• error handling systems (e.g. exception, call stack)
• tracing
• metricising (prometheus, micrometer)
• agent (e.g. JMX)

Telemetry:

• 3 Pillars of observability
  • traces
  • metrics
  • logs
• user activity
• call stacks
• custom protocols
