每天轮换日志文件，日志文件名格式为 {label}-YYYY-MM-DD.log。
[!Important] Default retained log files
因为它供内部使用，所以默认日志会保留 60 天。

// log info
logger.info('detail blocklet', { did: 'z8iZpWP3gto8RWk9UHfvAaYtqX5wZ3Mz9BrHA' });
// [2020-08-12 17:26:28] [info] "detail blocklet" {"did":"z8iZpWP3gto8RWk9UHfvAaYtqX5wZ3Mz9BrHA"}
// log error: must pass an object
