Default console observable plugin for logging output

core observable default console

observable-default

observable-default is the built-in observable plugin for BSB.

It provides baseline logging and trace-aware output to stdout/stderr.

What It Provides

Debug/info/warn/error logging
Trace-aware message formatting
Lightweight diagnostics for development

Minimal Example

default:
  observable:
    observable-default:
      plugin: observable-default
      enabled: true
      config: {}

Behavior Notes

Debug logs are typically suppressed in production mode
Output is console-based (no external collector by default)
No plugin-specific config fields are required for observable-default

When To Replace

Use a dedicated observable plugin (observable-pino, observable-winston, observable-opentelemetry, observable-graylog, syslog) when you need centralized logs, metrics, and tracing pipelines.

Observable-Default In Production

observable-default is intentionally lightweight. It is good for local and baseline runtime logs, but it is not a full external observability backend.

Behavior

Console output only
Trace metadata formatting
Debug logs suppressed in production mode
No external transport, retention, or aggregation

Recommended Migration Path

For production-grade operations, switch to one of:

observable-pino
observable-winston
observable-opentelemetry
observable-graylog
syslog

Default Plugin Config Example

default:
  observable:
    observable-default:
      plugin: observable-default
      enabled: true
      config: {}

observable-default itself has no required plugin-specific options.

Why Replace

Centralized log search
Long-term retention
Distributed trace export
Metrics dashboards/alerts
