package dela

import "go.dedis.ch/dela"

Package dela defines the logger.

Dela stands for DEDIS Ledger Architecture. It defines the modules that will be combined to deploy a distributed public ledger.

Dela is using a global logger with some default parameters. It is disabled by default and the level can be increased using a environment variable:

LLVL=trace go test ./...
LLVL=info go test ./...
LLVL=debug LOGF=$HOME/dela.log go test ./...

Constants ¶

const EnvLogFile = "LOGF"

EnvLogFile is the name of the environment variable to log in a given file.

const EnvLogLevel = "LLVL"

EnvLogLevel is the name of the environment variable to change the logging level.

Variables ¶

var Logger = zerolog.New(consoleOut).Level(defaultLevel).
	With().Timestamp().Logger().
	With().Caller().Logger().
	Hook(promHook{})

Logger is a globally available logger instance. By default, it only prints error level messages but it can be changed through a environment variable.

var PromCollectors []prometheus.Collector

PromCollectors exposes Prometheus collectors created in Dela. By default Dela doesn't register the metrics. It is left to the user to use the registry of its choice and register the collectors. For example with the default:

prometheus.DefaultRegisterer.MustRegister(PromCollectors...)

Note that the collectors can be registered only once and will panic otherwise. This slice is not thread-safe and should only be initialized in init() functions.
