Logger config

[ckanner]

Otelcol use zap to logger something. But now, I can only config my looger by set log-level and log-profile.

How can I config my logger custom? I want to set something like Encoding, OutputPaths, logrotate and so on.

Can you provide details how others do this? Also what are the configs you want to offer?

@bogdandrutu I think we could use Zap's config struct as-is (it has yaml and json tags)

https://github.com/uber-go/zap/blob/master/config.go#L58

This would allow the user to completely configure Zap to their liking.

Sounds good, it should probably be part of the "service" configuration :)

@bogdandrutu
I would like to work on it and make a pr for adding following configs, which just copied the zap config from the link above.
I am not going to add SamplingConfig and EncoderConfig which include interfaces for custom implementation.

// DisableCaller stops annotating logs with the calling function's file
// name and line number. By default, all logs are annotated.
DisableCaller bool `mapstructure:"disableCaller"`

// DisableStacktrace completely disables automatic stacktrace capturing. By
// default, stacktraces are captured for WarnLevel and above logs in
// development and ErrorLevel and above in production.
DisableStacktrace bool `mapstructure:"disableStacktrace"`

// OutputPaths is a list of URLs or file paths to write logging output to.
// See Open for details.
OutputPaths []string `mapstructure:"outputPaths"`

// ErrorOutputPaths is a list of URLs to write internal logger errors to.
// The default is standard error.
//
// Note that this setting only affects internal errors; for sample code that
// sends error-level logs to a different location from info- and debug-level
// logs, see the package-level AdvancedConfiguration example.
ErrorOutputPaths []string `mapstructure:"errorOutputPaths"`

// InitialFields is a collection of fields to add to the root logger.
InitialFields map[string]interface{} `mapstructure:"initialFields"``

@pureklkl - What are the options for logrotate in OTelCol? Could you please provide sample configuration?
