Blindsight

Suffering in silence, you check the logs for fresh telemetry.

You think: That can’t be right.

Blindsight, Peter Watts

Blindsight is “observability through logging” where observability is defined as baked in high cardinality structured data with field types. The name is taken from Peter Watts’ excellent first contact novel, Blindsight.

Blindsight is a logging library written in Scala that wraps SLF4J to add useful features that solve several outstanding problems with logging:

The only hard dependency is the SLF4J API, but the DSL functionality is only implemented for Logback with logstash-logback-encoder.

Blindsight is a pure SLF4J wrapper: it delegates all logging through to the SLF4J API and does not configure or manage the SLF4J implementation at all.

Versions are published for Scala 2.11, 2.12, and 2.13.

It is heavily informed by the blog posts at tersesystems.com and the diagnostic logging showcase.
