name	golem-logging-scala
description	Adding logging to a Scala Golem agent. Use when the user asks about logging, log messages, log levels, wasi:logging, golem.wasi.Logging, or printing debug/info/error output from a Scala agent.

Logging from a Scala Agent

The Scala SDK provides golem.wasi.Logging — a typed facade over wasi:logging/logging with convenience methods for each log level and an optional context parameter.

Quick Start

Import and use the Logging object directly — no initialization needed:

import golem.wasi.Logging

Logging.info("order created: " + orderId)
Logging.debug("processing item: " + itemId)
Logging.warn("retry attempt " + attempt + " for request " + reqId)
Logging.error("failed to connect: " + err.getMessage)

Log Levels

Method	WASI Level	Use for
Logging.trace(msg)	trace	Fine-grained control flow
Logging.debug(msg)	debug	Debugging information
Logging.info(msg)	info	Monitoring, normal operations
Logging.warn(msg)	warn	Hazardous situations
Logging.error(msg)	error	Serious errors
Logging.critical(msg)	critical	Fatal errors

Context Strings

Every method accepts an optional context parameter (defaults to ""). Use it to scope log entries to a subsystem or request:
