Log Manager

Log manager plugin allows to view and modify log levels of loggers using REST API.

API

• List all registered loggers:

  curl -X GET http://<host>:<port>/log/list

• Set log level for a registered logger: curl -X PUT http://<host>:<port>/log/<logger-name>/<log-level>

  <log-level> is one of debug,info,warning,error,fatal,panic

<host> and <port> are determined by configuration of rest.Plugin.

Types

type Conf

type Conf struct {
	DefaultLevel string
	Loggers      []ConfLogger
}

Conf is a binding that supports to define default log levels for multiple loggers

func NewConf

func NewConf() *Conf

NewConf creates default configuration with InfoLevel & empty loggers. Suitable also for usage in flavor to programmatically specify default behavior.

type ConfLogger

type ConfLogger struct {
	Name  string
	Level string //debug, info, warning, error, fatal, panic
}

ConfLogger is configuration of a particular logger. Currently we support only logger level.

type Deps

type Deps struct {
	Log                 logging.PluginLogger //inject
	PluginName          core.PluginName      //inject
	config.PluginConfig                      //inject

	LogRegistry logging.Registry  // inject
	HTTP        rest.HTTPHandlers // inject
}

Deps groups dependencies injected into the plugin so that they are logically separated from other plugin fields.

type LoggerData

type LoggerData struct {
	Logger string `json:"logger"`
	Level  string `json:"level"`
}

LoggerData encapsulates parameters of a logger represented as strings.

type Plugin

type Plugin struct {
	Deps
	*Conf
}

Plugin allows to manage log levels of the loggers using HTTP.

func (*Plugin) AfterInit

func (lm *Plugin) AfterInit() error

AfterInit is called at plugin initialization. It register the following handlers:

• List all registered loggers: > curl -X GET http://localhost:<port>/log/list
• Set log level for a registered logger: > curl -X PUT http://localhost:<port>/log/<logger-name>/<log-level>

func (*Plugin) Close

func (lm *Plugin) Close() error

Close is called at plugin cleanup phase.

func (*Plugin) Init

func (lm *Plugin) Init() error

Init does nothing
