Logger

The Logger capability provides WASM functions with the ability to log arbitrary data. Much like a traditional logger framework, this capability offers multiple log levels.

By default Debug and Trace level logs are disabled. To enable these log levels to consult the configuration options for Tarmac.

Error

Critical errors within the system.

_, err := wapc.HostCall("tarmac", "logger", "error", []byte("This is the data that should be logged"))

Warn

Non-critical errors within the system.

_, err := wapc.HostCall("tarmac", "logger", "warn", []byte("This is the data that should be logged"))

Info

Informational logs.

_, err := wapc.HostCall("tarmac", "logger", "info", []byte("This is the data that should be logged"))

Debug

Request level errors & informational logs. Disabled by default, calls to Debug logging are ignored unless debug is enabled for the Tarmac host.

_, err := wapc.HostCall("tarmac", "logger", "debug", []byte("This is the data that should be logged"))

Trace

Low-level details of execution. Disabled by default, calls to Trace logging are ignored unless trace is enabled for the Tarmac host.

_, err := wapc.HostCall("tarmac", "logger", "trace", []byte("This is the data that should be logged"))
